TROUBLE DIAGNOSES
CONSULT (Cont'd)
REAL TlME DIAGNOSIS IN DATA MONITOR MODE
CONSULT has two kinds of triggers and they can be selected by touching "SETTINGJy in "DATA MONITOR"
mode.
1. "AUTO TRIG" (Automatic trigger):
The malfunction will be identified on the CONSULT screen in real time.
In other words, malfunction item will be displayed at the moment the malfunction is detected by ECM. GI
DATA MONITOR can be performed continuously until a malfunction is detected. However, DATA MONI-
TOR cannot continue any longer after the malfunction detection.
2. "MANU TRIG" (Manual trigger):
Malfunction item will not be displayed automatically on CONSULT screen even though a malfunction
is detected by ECM.
DATA MONITOR can be performed continuously even though a malfunction is detected. I
AT
Use these triggers as follows: . 1. "AUTO TRIG"
While trying to detect the DTC by performing the "DTC CONFIRMATION PROCEDURE", be sure to BR
select to "DATA MONITOR (AUTO TRIG)" mode. You can confirm the malfunction at the moment it is
detected.
While narrowing down the possible causes, CONSULT should be set in "DATA MONITOR (AUTO ST
TRIG)" mode, especially in case the incident is intermittent.
When you are inspecting the circuit by gently shaking (or twisting) the suspicious connectors, compo-
Rs
nents and harness in the "DTC CONFIRMATION PROCEDURE, the moment a malfunction is found
the malfunction item will be displayed. (Refer to GI section,
"Incident
Simulation Tests" in
"HOW TO
PERFORM EFFICIENT DIAGNOSIS
FOR AN ELECTRICAL INCIDENT'.) HA
2. "MANU TRIG"
If the malfunction is displayed as soon as "DATA MONITOR" is selected, reset CONSULT to "MANU
TRIG".
By selecting "MANU TRIG" you can monitor and store the data. The data can be utilized for
further diagnosis, such as a comparison with the value for the normal operating condition.

HOW TO ERASE SELF-DIAGNOSTIC RESULTS
To facilitate cause investigation of malfunction that is less likely to
reappear, the TCM always stores self-diagnostic results during cus-
tomer operation. This memory cannot be erased even if ignition
switch
is turned ON and OFF repeatedly. To erase the seif-diag-
nostic
results, turn ignition switch
OFF after self-diagnosis has
been performed, or use
"ERASE" function of CONSULT.

TCSlABS SYSTEM
Precautions for Trouble
Diagnosis
After performing trouble diagnosis, be sure to erase trouble stored in memory.
Refer to "CONSULT for
TCS/ABS Control Unit Control System"
(BR-27), "Self-diagnosis for TCSIABS
Control Unit Control System"
(BR-34), "CONSULT for Throttle Control Unit Control System" (BR-37) or
"Self-diagnosis for Throttle Control Unit Control System"
(BR-41).
The concerns that are difficult to duplicate may be caused by faulty electrical connections. Move harnesses
or harness connectors by hand to check if there is any poor mating of connector halves or faulty connec-
tion. Do not force to open a connector terminal when using a circuit tester for inspection.
Read GI section thoroughly in advance and make sure of all the general precautions.
Basic Inspection
BASIC INSPECTION 1 - Brake fluid level and leakage
1. Check brake fluid level in reservoir tank. Replenish brake fluid if necessary.
2. Check for leakage at or around brake piping and ABS actuator. If leakage or seepage is noted, proceed
as follows:
If ABS actuator connectors are loose, tighten to specified torque. Recheck to ensure that leakage is no
longer present.
If flare nut threads at piping connectors or actuator threads are damaged, replace faulty parts with new
ones. Recheck to ensure that leakage is no longer present.
If brake fluid leaks through areas other than actuator connectors, wipe off using a clean cloth. Recheck
for leakage or seepage. If necessary, replace faulty parts with new ones.
If brake fluid leaks at or seeps through ABS actuator, wipe off using a clean cloth.
Recheck for leakage or seepage. If necessary, replace ABS actuator with new one.
CAUTION:
ABS actuator cannot be disassembled. Do not attempt to disassemble it.
3. Check brake disc rotors and pads for proper operation.
BASIC INSPECTION 2 - Loose power line terminal
Check battery terminals (positive and negative) and battery mounting (ground) for looseness. If necessary,
tighten to specified torque. Check the battery for lower voltage.
BASIC INSPECTION 3 - SLlP indicator lamp, TCS OFF indicator lamp and ABS warning
lamp
Turn ignition switch "ON" to ensure that TCS OFF indicator lamp lights up. If TCS OFF indicator lamp does
not light, check TCS OFF indicator lamp circuit.
Turn ignition switch
"ON" to ensure that SLlP indicator lamp lights
up. If SLlP indicator lamp does not light,
check SLlP indicator lamp circuit.
Turn ignition switch "ON" to ensure that ABS warning lamp lights up. If ABS warning lamp does not light,
check ABS warning lamp circuit.
Check that the SLlP indicator lamp and the ABS warning lamp go off approx.
1 second after the engine
has started. If either of the lamps still remains on, perform the self-diagnosis for TCSIABS control unit
control system and the self-diagnosis for throttle control unit control system.
After driving vehicle at approx. 30
km/h
for approx.
1 minute, check to ensure that the SLlP indicator lamp
and the ABS warning lamp are off. If either of the lamps still remains on, perform the self-diagnosis for
TCS/ABS
control unit control system and the self-diagnosis for throttle control unit control system.
Check that the TCS OFF indicator lamp turns ON and OFF when the TCS OFF switch is turned to
ON
and OFF respectively, with the engine running. If the lamp status does not correspond to the switch
position, check the TCS OFF switch circuit.
Check that the TCS OFF indicator lamp goes off when the engine has started with the TCS OFF switch
OFF. If the TCS
OFF indicator lamp does not go off even 10 seconds after the engine has started, per-
form the self-diagnosis for TCSIABS control unit control system and the self-diagnosis for throttle control
unit control system.
After driving vehicle at approx.
30 kmlh for approx. 1 minute with the TCS OFF switch OFF, check to ensure
that the TCS OFF indicator lamp is off. If the TCS OFF indicator lamp lights up, perform the
self-diagno-
sis for
TCS/ABS
control unit control system and the self-diagnosis for throttle control unit control system.
After performing self-diagnosis procedures, be sure to erase trouble stored in memory.
