YES >> Connect connectors, and perform the self-diagnosis. The vehicle harness has the intermediate
connector. Refer to the vehicle wiring diagram, always check it.
NO >> Repair or replace the disconnected connector.
Symptom 8: During ESP/TCS/ABS Control, Vehicle Behavior is Jerky.EFS001AZ
Inspection procedure
1. ENGINE SPEED SIGNAL INSPECTION
Perform “DATA MONITOR” with CONSULT-II for the ESP/TCS/ABS control unit.
Is the engine speed at idle 400 rpm or higher?
YES >> Normal
NO >> GO TO 2.
2. SELF-DIAGNOSIS RESULT CHECK 1
Perform the ESP/TCS/ABS control unit self-diagnosis.
Is the self-diagnosis results displayed?
YES >> After checking and repairing the applicable item, perform the ESP/TCS/ABS control unit self-
diagnosis again.
