registration of all NATS ignition key IDs must be carried out
with CONSULT-II using NATS program card.
Therefore, be sure to receive all keys from vehicle owner.
Regarding the procedures of NATS initialization and NATS
ignition key ID registration, refer to CONSULT-II operation
manual, NATS.
Malfunction Indicator (MI)
DESCRIPTION
The MI is located on the instrument panel.
1. The MI will light up when the ignition switch is turned ON with-
out the engine running. This is a bulb check.
I If the MI does not light up, refer to EL section (ªWARNING
LAMPS AND CHIMEº) or see EC-310.
2. When the engine is started, the MI should go off. If the MI remains on, the on board diagnostic system has
detected an engine system malfunction.

Diagnostic test mode I Ð Bulb check
In this mode, the MI on the instrument panel should stay ON. If it remains OFF, check the bulb. Refer to EL
section, ªWARNING LAMPS AND CHIMEº or see EC-310.
Diagnostic test mode I Ð Malfunction warning
MICondition
ON When the malfunction is detected or the ECM's CPU is malfunctioning.
OFF No malfunction.
Diagnostic test mode II Ð Self-diagnostic results
In this mode, DTC is indicated by the number of blinks of the MI as shown below.
Long (0.6 second) blinking indicates the two LH digits of number and short (0.3 second) blinking indicates the
two RH digits of number. For example, the MI blinks 10 times for 6 seconds (0.6 sec x 10 times) and then it
blinks three times for about 1 second (0.3 sec x 3 times). This indicates the DTC ª1003º.
In this way, all the detected malfunctions are classified by their DTC numbers. The DTC ª0505º refers to no
malfunction. (See TROUBLE DIAGNOSIS Ð INDEX, EC-7.)
How to erase diagnostic test mode II (Self-diagnostic results)
The DTC can be erased from the backup memory in the ECM when the diagnostic test mode is changed from
Diagnostic Test Mode II to Diagnostic Test Mode I. (Refer to ªHow to Switch Diagnostic Test Modesº, EC-36.)
I If the battery terminal is disconnected, the DTC will be lost from the backup memory within 24
hours.
I Be careful not to erase the stored memory before starting trouble diagnoses.

Ignition switch ON
After ignition switch has turned to ON, the glow relay turns ON
for a certain period of time in relation to engine coolant
temperature, allowing current to flow through glow plug.
I Cranking
The glow relay turns ON, allowing current to flow through glow
plug.
I Starting
After engine has started, current continues to flow through glow
plug (after-glow mode) for a certain period in relation to engine
coolant temperature.
When engine speed exceeds approximately 4,800 rpm, current
flow through glow plug is interrupted.
The glow indicator lamp turns ON for a certain period of time in
relation to engine coolant temperature at the time glow relay is
turned ON.
COMPONENT DESCRIPTION
Glow plug
I The glow plug is provided with a ceramic heating element to
obtain a high-temperature resistance. It glows in response to a
signal sent from the ECM, allowing current to flow through the
glow plug via the glow relay.
I This engine uses two types of glow plugs.
Type A has a blue or yellow paint mark.
Type B has no paint mark.
The location of the paint mark is shown in the figure.

Component Description
Engine oil pressure switches that monitor oil pressure at high
engine speed (switch-2) and oil pressure at low engine speed
(switch-1) are located on oil passage.
For detection of oil pressure at low engine speed, engine oil pres-
sure switch-1 turns oil pressure warning lamp ON if oil pressure
drops too low under normal engine running speed (below specified
pressure of engine oil pressure switch-1 at low engine speed).
For detection of oil pressure at high engine speed, engine oil pres-
sure switch-2 sends an ON signal to the ECM if oil pressure drops
lower than specified value when engine is running at high speed or
under high loading. Then the ECM turns oil pressure warning lamp
ON.
