Cruise Control Switch Circuit

CRUISE CONTROL: CRUISE CONTROL SYSTEM: Cruise Control Switch Circuit
- Cruise Control Switch Circuit

DESCRIPTION

This circuit sends signals to the ECM depending on the cruise control main switch condition.

The battery supplies positive (+) battery voltage to the cruise control main switch. Then terminal CCS of the ECM receives the voltage according to the switch condition.

INSEPCTION PROCEDURE

PROCEDURE

1. READ VALUE USING TECHSTREAM (CRUISE CONTROL MAIN SWITCH)

(a) Check the Data List for proper functioning of the cruise control main switch.

Cruise Control





OK:

When cruise control main switch operation is performed, the results will be same as above.

OK -- REPLACE ECM
NG -- Continue to next step.

2. INSPECT CRUISE CONTROL MAIN SWITCH





(a) Measure the resistance of the switch.

Standard resistance:





NG -- REPLACE CRUISE CONTROL MAIN SWITCH
OK -- Continue to next step.

3. INSPECT SPIRAL CABLE SUB-ASSEMBLY





(a) Measure the resistance of the spiral cable.

Standard resistance:





NG -- REPLACE SPIRAL CABLE SUB-ASSEMBLY
OK -- Continue to next step.

4. CHECK WIRE HARNESS (SPIRAL CABLE - ECM AND BODY GROUND)





(a) Disconnect the E5 ECM connector.

(b) Disconnect the A spiral cable connector.

(c) Measure the resistance of the wire harness side connectors.

Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
