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 cruise control main switch. Terminal 40 (CCS) of the ECM receives the voltage which varies according to the switch condition.

INSPECTION PROCEDURE

PROCEDURE

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

(a) Using the Techstream, read the Data List Scan Tool Testing and Procedures.

Cruise Control





OK:

The display is as specified in the normal condition column.

NG -- INSPECT CRUISE CONTROL MAIN SWITCH

OK -- PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE Symptom Related Diagnostic Procedures

2. INSPECT CRUISE CONTROL MAIN SWITCH

(a) Remove the cruise control main switch Removal.





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

Standard Resistance:





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

3. INSPECT CRUISE CONTROL SWITCH WIRE

(a) Remove the cruise control switch wire.





(b) 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.

4. INSPECT SPIRAL CABLE WITH SENSOR SUB-ASSEMBLY

(a) Remove the spiral cable with sensor Removal.





(b) If there are any defects as follows, replace the spiral cable with sensor with a new one: scratches, cracks, dents or chips on the connector or spiral cable with sensor.

(c) Check the spiral cable with sensor.

(1) Set the spiral cable with sensor to the center position Installation.

(2) Rotate the spiral cable with sensor 2.5 times clockwise and measure the resistance according to the value(s) in the table below. Then rotate the spiral cable with sensor 5 times counterclockwise and measure the resistance according to the value(s) in the table below.

NOTICE:
As the spiral cable with sensor may break, do not rotate the spiral cable with sensor more than the specified amount.

Standard Resistance:





(3) Set the spiral cable with sensor to the center position and rotate the spiral cable with sensor 2.5 times clockwise. Then, while rotating the spiral cable with sensor 5 times counterclockwise, measure the resistance according to the value(s) in the table below.

Standard Resistance:





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

5. CHECK HARNESS AND CONNECTOR (SPIRAL CABLE WITH SENSOR - ECM AND BODY GROUND)

(a) Disconnect the C8 spiral cable with sensor connector.

(b) Disconnect the A35 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
