Cruise Control Switch Circuit
CRUISE CONTROL: CRUISE CONTROL SYSTEM: Cruise Control Switch Circuit
- Cruise Control Switch Circuit
DESCRIPTION
This circuit sends a signal to the ECM depending on the cruise control main switch condition. The battery supplies positive (+) battery voltage to the circuit control switch. Then terminal CCS of the ECM receives the voltage according to the switch condition.

INSPECTION 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 are the same as above.
NG -- INSPECT CRUISE CONTROL SWITCH
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE Cruise Control System
2. INSPECT CRUISE CONTROL SWITCH
(a) Remove the cruise control switch.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPLACE CRUISE CONTROL SWITCH Removal
OK -- Continue to next step.
3. INSPECT SPIRAL CABLE SUB-ASSEMBLY
(a) Disconnect the z2 cruise control switch wire connector.
(b) Disconnect the L134 cable connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPLACE SPIRAL CABLE SUB-ASSEMBLY Removal
OK -- Continue to next step.
4. INSPECT CRUISE CONTROL SWITCH WIRE
(a) Disconnect the z2 spiral cable connector.
(b) Disconnect the A cruise control switch connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPLACE CRUISE CONTROL SWITCH WIRE
OK -- Continue to next step.
5. CHECK HARNESS AND CONNECTOR (SPIRAL CABLE - ECM AND BODY GROUND)
(a) Disconnect the L134 cable connector.
(b) Disconnect the A13 ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- REPLACE ECM Removal
