Cruise Control Switch Circuit

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

INSPECTION PROCEDURE

PROCEDURE

1. INSPECT CRUISE CONTROL MAIN SWITCH





(a) Turn the ignition switch off.
(b) Disconnect the cruise control main switch connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:





(d) Reconnect the cruise control main switch connector.
NG -- REPLACE CRUISE CONTROL MAIN SWITCH
OK -- Continue to next step.
2. CHECK HARNESS AND CONNECTOR (CRUISE CONTROL MAIN SWITCH - SPIRAL CABLE SUB-ASSEMBLY)
(a) Disconnect the spiral cable side connector.





(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:





(c) Reconnect the spiral cable side connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
3. INSPECT SPIRAL CABLE SUB-ASSEMBLY





(a) Disconnect the spiral cable connector on the ECM side.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:





NG -- REPLACE SPIRAL CABLE SUB-ASSEMBLY
OK -- Continue to next step.
4. CHECK HARNESS AND CONNECTOR (SPIRAL CABLE SUB-ASSEMBLY - BODY GROUND)





(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (SPIRAL CABLE SUB-ASSEMBLY - BODY GROUND)
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (SPIRAL CABLE SUB-ASSEMBLY - ECM)





(a) Disconnect the E7 ECM connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance (1GR-FE):





Standard Resistance (2TR-FE):





(c) Reconnect the ECM connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (SPIRAL CABLE SUB-ASSEMBLY - ECM)
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
