CIRCUIT OPERATION
Refer to
COMMENT ON TROUBLE SYMPTOM
The cause is probably the ABS-ECU malfunction.
PROBABLE CAUSES
The most likely causes for this case are:
• Damaged wiring harness or connector
• Malfunction of the brake modulator hydraulic unit
(integrated with ABS-ECU)
DIAGNOSIS
STEP 1. Check the following connectors.
•
Combination meter connector C-01
• Intermediate connector C-122
•
ABS-ECU connector B-118
Check the connectors for loose, corroded or dam-
aged terminals, or terminals pushed back in the con-
nector.
Q: Are the connectors and terminals in good
condition?
