Diagnosis Procedure
INSPECTION PROCEDURE
1.CONNECTOR INSPECTION
1. Disconnect the ABS actuator and electric unit (control unit) connector E125 and stop lamp switch connector E38.
2. Check the terminals for deformation, disconnection, looseness or damage.
Is the inspection result normal?
YES >> GO TO 2
NO >> Repair or replace as necessary.
2.STOP LAMP SWITCH INSPECTION
Check the voltage between the ABS actuator and electric unit (control unit) harness connector E125 terminal 41 and body ground.
Brake pedal depressed: Battery voltage (approx. 12V)
Brake pedal not depressed: Approx. 0V
Is the inspection result normal?
YES >> Perform self-diagnosis again. If the same results appear, replace ABS actuator and electric unit (control unit).
NO >> GO TO 3
3.STOP LAMP RELAY CIRCUIT INSPECTION
1. Disconnect the stop lamp relay harness connector E12.
2. Check the continuity between the ABS actuator and electric unit (control unit) harness connector E125 (B) terminal 41 and stop lamp relay harness connector E12 (A) terminal 4.
Continuity should exist.
Is the inspection result normal?
YES >> Refer to EXL-4, "Work Flow". Diagnosis and Repair Workflow
NO >> Repair or replace malfunctioning components.
Special Repair Requirement
