STANDARD FLOW OF DIAGNOSTIC TROUBLESHOOTING
Refer to GROUP 00 ± How to Use Troubleshooting/Inspection Service Points.
NOTES WITH REGARD TO DIAGNOSIS
The phenomena listed in the following table are not abnormal.
PhenomenonExplanation of phenomenon
System check soundWhen starting the engine, a thudding sound can sometimes be heard coming from inside
the engine compartment, but this is because the system operation check is being
performed, and is not an abnormality.
ABS operation sound1. Sound of the motor inside the ABS hydraulic unit operation. (whine)
2. Sound is the generated along with vibration of the brake pedal. (scraping)
3. When ABS operates, sound is generated from the vehicle chassis due to repeated
brake application and release.
(Thump: suspension; squeak: tyres)
ABS operation
(Long braking distance)For road surfaces such as snow-covered roads and gravel roads, the braking distance for
vehicles with ABS can sometimes be longer than that for other vehicles. Accordingly, advise
the customer to drive safely on such roads by lowering the vehicle speed and not being too
overconfident.
Shock during system
operation checkShock may be felt when the brake pedal is depressed slightly at a low driving speed. This
occurs due to ABS operation check (initial check at a vehicle speed of 8 km/h), and does
not indicate any malfunction.
Diagnosis detection condition can vary depending on the diagnosis code.
Make sure that checking requirements listed in the ªCommentº are satisfied when checking the trouble
symptom again.

diagnosis line.Malfunction of connector
Malfunction of harness wire
Refer to GROUP 13A ± Troubleshoot-
ing.
Inspection Procedure 2
Communication with MUT-II is impossible. (Communica-
tion with the one-shot pulse input signal only is

Probable cause
The cause is probably a defective one-shot pulse input circuit system of the diagnosis
line.Malfunction of connector
Malfunction of harness wire
Malfunction of ETACS-ECU
Check the harness wire between the
diagnosis connector and ETACS-ECU.OKCheck the following connectors:
C-35, C-90NG
Repair
NG
RepairOK
Check trouble symptom.NGReplace the ETACS-ECU.
Inspection Procedure 3
The ignition switch is turned to the OFF position and the
driver's side door is opened while the tail lamps or
headlamps are operating, but the light reminder warning
buzzer does not sound.
Probable cause
The cause is probably a defective lighting switch input circuit system or a defective
driver's side door switch input circuit system.Malfunction of driver's side door switch
Malfunction of harness or connector
Malfunction of buzzer-ECU or ETACS-ECU
Driver's side door switch input circuit
