TROUBLE DIAGNOSIS
Symptom 7: SLIP Indicator Lamp Does Not Illuminate
EFS001AY
Inspection procedure
1.SLIP INDICATOR LAMP BURNED-OUT BULB INSPECTION
Check for continuity between the power supply terminal of meter and terminal of ABS warning lamp.
Is inspection result OK?
OK >> GO TO 2.
NG >> Circuit malfunction in SLIP indicator lamp or combination meter
2.SLIP INDICATOR LAMP POWER CIRCUIT INSPECTION
Disconnect the meter connector. Check that the voltage between the vehicle-side harness terminal and body
ground is battery voltage (Approx. 12V).
Is inspection result OK?
YES >> GO TO 3.
NO >>
lFuse inspection
lInspection for harness and connectors between fuse block and meter
lCheck the power supply circuit (battery and ignition switch circuit).
3.SLIP INDICATOR LAMP HARNESS INSPECTION
1. Disconnect connectors for the ESP/TCS/ABS control unit and meter vehicle-side harness.
2. Check the harness between the meter and the ESP/TCS/ABS control unit for an open/shorted circuit.
Is inspection result OK?
OK >> GO TO 4.
NG >> Repair or replace the disconnected harness.
4.SLIP INDICATOR LAMP CONNECTOR INSPECTION
Check connectors for the ESP/TCS/ABS control unit and meter vehicle-side harness.
Is inspection result OK?
YES >> Connect connectors, and perform the self-diagnosis. The vehicle harness has the intermediate
connector. Refer to the vehicle wiring diagram, always check it.
NG >> 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
Perform²DATA MONITOR²with 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.
NO >> GO TO 3.
