INSPECTION PROCEDURE

PROCEDURE

1. CHECK FOR ANY FOREIGN OBJECT
(a) Check that no foreign object is in the steering pad switch cover.
OK:
No foreign object.
NG -- REMOVE FOREIGN OBJECT
OK -- Continue to next step.
2. CHECK WIRE HARNESS (INSTRUMENT CLUSTER FINISH PANEL CENTER - SPIRAL CABLE)




(a) Disconnect the M6 panel connector.
(b) Disconnect the C10 cable connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
OK -- Continue to next step.
3. CHECK STEERING PAD SWITCH MODULATOR (TEL 2 VOLTAGE)




(a) Measure the voltage of the switch.
Standard voltage:






NG -- REPLACE STEERING PAD SWITCH MODULATOR
OK -- Continue to next step.
4. CHECK CRUISE CONTROL MAIN SWITCH ASSEMBLY




(a) Disconnect the switch connectors.
(b) Measure the resistance of the switch.
Standard resistance:






NG -- REPLACE CRUISE CONTROL MAIN SWITCH ASSEMBLY
OK -- Continue to next step.
5. INSPECT SPIRAL CABLE SUB-ASSEMBLY




(a) Disconnect the cable connectors.
(b) Measure the resistance of the cable.
Standard resistance:






NG -- REPLACE SPIRAL CABLE SUB-ASSEMBLY
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
