The procedure for fabricating an LED test lamp is
fully described in the El ectrical System section.
If a conventional test lamp with a filament type
bulb is to be used, ensure that the current draw of the
test lamp does not exceed 0.3 amp to avoid damage to
the electronic components.
To check the current draw connect an accurate
ammeter, such as the multimeter described previ-
ously, in series with the test lamp and a battery.
If the ammeter reads less than 0.3 amp the test
lamp is suitable.
Tachometer
(1) Disconnect the resistor from the tachometer
pick-up wiring connector which is located on the
ignition coil wiring harness, and connect the positive
lead of an accurate tachometer to the brown wire
terminal in the wiring connector. (2) Connect the negative lead to a good earthing
point.
View showing the location of the tachometer pickup
wiring connector with the resistor installed.
Timing Light
(1) Connect the timing light to the engine fol-
lowing the instrument manufacturers instructions.
NOTE: Do not connect or disconnect the
timing light with the engine running as
voltage surges could damage the alternator
or control unit. Do not allow the high
tension leads to open circuit with the engine
running as damage to the engine manage-
ment system could result.
(2) Do not connect the timing light positive lead
to the alternator output terminal. Where possible,
connect the power leads of the timing light to an
external power source to prevent possible transient
voltages damaging the alternator or control unit.
4. SYSTEM DIAGNOSIS AND ADJUSTMENTS
NOTE: Due to the use of complex electronic
components in the engine management sys-
tem, the diagnosis and testing procedures
described in this section should not be
carried out by persons lacking an under-
standing of electronics and the precautions
associated with the servicing of electronic
components. It is rec ommended that should
a fault arise in the system, the vehicle be
referred to an authorized workshop.
The control unit can be damaged by
component faults not indicated by the self
diagnosis codes and the renewal of the
control unit without lo cating the cause of
the failure will result in the failure of the
replacement unit. It is for this reason that
the practice of substituting components to
isolate faults is not recommended.
Prior to performing any of the follow-
ing operations, refer to the Service Pre-
cautions and Procedures heading.
PRELIMINARY CHECKS
Prior to performing the Self Diagnosis Test Pro-
cedures, perform the following preliminary checks and
rectify any problems as necessary.
(1) Check for an adequate supply of fuel in the
fuel tank. (2) Check the wiring connectors and earth points
of all engine management components for clean,
secure connections. To prevent damage to the control
unit, disconnect the negative battery terminal before
disconnecting any engine ma nagement wiring connec-
tors. (3) Check the condition of the battery. Refer to
the Electrical System sectio n for checking procedures.
Rectify any faults as necessary. (4) Check the air cleaner element for restriction.
(5) Check for air leaks at the throttle body, inlet
manifold and all related hoses. (6) Check the fuel pump pr essure as described
later in this section. (7) Ensure that the engine is in a satisfactory
mechanical condition and is in tune. Refer to the
Engine and Engine Tune-up sections as necessary.
SELF DIAGNOSIS
This function is very useful in locating system
faults particularly intermittent problems. However,
the self diagnosis mode does not provide comprehen-
sive testing of the engine management system, and
therefore should always be used in conjunction with
the other test procedures described later, in order to
accurately locate system faults.
To Interpret Self Diagnosis Codes
Once the self diagnosis mode is activated, various
fault codes will be displayed as a series of flashes by
the ECM warning lamp on the instrument cluster.
Page 90 of 238
90 Fuel and Engine Management
To identify the code number, count the number of
times the ECM warning lamp flashes. Each fault code
comprises two groups of flashes separated by a 1.2
second pause. The first group represents tens and the
second group represents single units. For example 1
flash followed by a 1.2 second pause followed by 4
flashes would be code number 14. Similarly 4 flashes
followed by a 1.2 second pause followed by 2 flashes
would be code number 42.
The code will be displayed three times. If more
than one fault code is present, the self diagnosis
system will indicate each one in numerical order, with
a 3.2 second pause between each code, and then
repeat the sequence.
The fault codes can be identified as follows:
CODE NUMBER FAULT AREA
12 Satisfactory operation
13 Oxygen sensor open circuit
14 Coolant temperature sensor circuit (voltage low)
15 Coolant temperature sensor circuit (voltage high)

If code 55 is displayed, refer to the Control Unit
heading, perform the circuit test procedure and rectify
the cause of the code before proceeding.
If the ECM warning lamp flashes codes other than
code 55, check the wiring harness between the diag-
nostic link connector terminal B and the control unit
wiring connector terminal A9 for shorts. Repair or
renew the wiring harness as necessary.
If no fault can be found, renew the control unit.
If the ECM warning lamp does not illuminate,
proceed as follows:
(a) Check the METER fuse located in the fuse
panel adjacent to the steering column and the fusible
links located in the fusible link connecting block at the
rear of the battery. Renew the fuse or fusible links as
necessary. (b) Check the wiring harness to the instrument
cluster. Repair or renew the harness. (c) Check the Check Engine lamp bulb. Renew if
necessary. (d) Check the EGI relay. Renew as necessary.
(3) Connect a jumper lead across terminals A
and B on the diagnostic link connector located under
the front passengers seat above the control unit.
(4) Note the codes indicated by the flashing
ECM warning lamp.
If code 12 is displayed, the system is operating
correctly.
If codes other than code 12 are displayed, refer to
the component or circuit test procedure under the
appropriate heading as indicated by the code number.
If more than one code is being displayed, test each
indicated fault working in the order of display of the
code numbers.

5. TEST EQUIPMENT AND SOME APPLICATIONS
Special Equipment Required:
To Make Test Lamp or Jumper Lead — Soldering
iron
When working on the electrical system, a test
lamp and jumper leads can be very useful to check
circuits.
TO MAKE A JUMPER LEAD
The minimum materials required to make a
jumper lead are one length of 4 mm wire and two
small alligator clips.
Grouping of materials to construct jumper leads of
various sizes.
Bare both ends of a suitable length of 4 mm
wire. Connect a small alligato r clip to each end of
the wire. Solder and tape the connections. Test the jumper lead for continuity by re-
moving one battery cable and connecting the lead
between the cable and the battery terminal. Turn the
ignition On and the dashboard warning lamps should
operate indicating a completed circuit through the
jumper lead. Remove the jumper lead from the circuit and
reconnect the battery.
NOTE: Make a few jumper leads of various
lengths using different sizes and types of
alligator and battery clips.
TO MAKE A TEST LAMP
Due to the extensive use of electronic components
in the electrical system, an LED (light emitting diode)
test lamp can be made from a suitable length of 3 mm
wire, an alligator clip, an LED, a 1/4 watt 560 ohm
resistor, a suitable case such as an old ball point pen
case and a length of rod or wire sharpened to form a
probe.
(1) Solder the length of wire to the K (cathode)
Page 194 of 238
194 Electrical System
Schematic of LED test lamp. Ensure that the connec-
tions to the K (cathode) lead and A (anode) lead of the LED are as illustrated.
lead of the LED. The K lead is the shorter of the two
leads and is adjacent to the flat on the LED.
Solder the 560 ohm resister to the A (anode)
lead of the LED. Solder a short length of wire to the other lead
of the resistor and to the probe. Drill a hole in the side of the case to accept
the wire attached to the K lead of the LED. Mount the probe in the case. If using a pen
case, push the probe through the lower end of the pen
after removing the refill. Push the lead attached to the K lead of the
LED through the hole made in the side of the case and
solder the alligator clip to the lead.
Mount the LED to the case. If using a pen
case, the LED may be mounted in the plug at the top
of the pen after drilling the plug to accept the LED. Suitably attach the probe to the case using
adhesive or tape.
TO TEST SWITCHES
Disconnect the wires from the switch.
Using a test lamp, test each wire to locate the
power wire. It may be nec essary to turn the ignition
On as the switch may be wired through the ignition
circuit. Disconnect the test lamp and connect a jumper lead between the power wire and the wire
from the other side of the switch.
If the circuit functions, the switch can be consid-
ered faulty and should be renewed. Refer to the
heading Switches and Controls.
TO TEST BULBS
Remove the bulb from the bulb holder.
Connect a jumper lead between the positive
terminal of a battery a nd the base of the bulb.
Connect another jumper lead between the
negative battery terminal and the contact on the base
of the bulb. The bulb should illuminate. If the bulb has two filaments, connect the jumper
lead to the second contact on the base of the bulb. The
second filament should illuminate.
If the bulb fails to illuminate, it should be
renewed with a bulb of the correct voltage and
wattage.
TO TEST CIRCUITS
Turn the circuit switch On.
Using a test lamp, check for power at one of
the circuit connections. A fuse is a good starting point.
If power is available, reconnect the connector and
continue checking towards the motor or bulb end of
the circuit.
If power is not available, continue checking
towards the battery or switch end of the circuit.
6. BATTERY
Special Equipment Required: To Test — Hydrometer

internally, while a high reading indicates an open
circuit or high resistance in the windings. In both
cases a new rotor assembly will have to be installed.
Stator Windings
The stator test is carried out using a test lamp.
The stator leads must be detached from the
diode pack.
Connect a jumper lead from the negative
terminal of a charged 12 volt battery to the stator
winding frame. Connect one en d of a test lamp to the
battery positive terminal, the other end of the test
lamp to the stator lead, one at a time. Should the test lamp illuminate, however
dimly, a short circuit is indicated and the stator
assembly must be renewed.
Diodes
On some models the diod es may be tested after
disconnection. Testing can be done by using a 12 volt
battery and a 1.5 watt bulb in series with a jumper
lead.
Connect a jumper lead from the negative
terminal of a charged battery to the carrier/bracket
holding the diode to be tested. Connect one end of a test lamp to the battery
positive terminal and the other end of the lamp to the
diode lead. Note whether the lamp is illuminated and
then reverse the connections on the battery. If the lamp was illuminated in both direc-
tions or was not illuminated at all, the diode is faulty
and the diode pack/heat sink must be renewed.
Brush Springs and Brushes
Check the brush spring s for overheating and
distortion, check for binding in the brush holder.
Check the brush length and renew as neces-
sary. Refer to Specifications for the correct dimen-
sions. TO ASSEMBLE
