Clutch Switch Circuit

CRUISE CONTROL: CRUISE CONTROL SYSTEM: Clutch Switch Circuit
- Clutch Switch Circuit

DESCRIPTION

Clutch switch circuit inspection is necessary for manual transaxle vehicles.

When the clutch pedal is released, the ECM receives positive (+) battery voltage through the ECU- IG fuse. While depressing the clutch pedal, the clutch switch sends a signal to terminal D of the ECM. The ECM cancels cruise control drive when terminal D receives the signal.

INSPECTION PROCEDURE

PROCEDURE

1. INSPECT ECM

(a) Disconnect the B33 ECM connector.





(b) Turn the ignition switch ON.

(c) Measure the voltage according to the value(s) in the table below.

Standard voltage:





NG -- INSPECT CLUTCH SWITCH

OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE Symptom Related Diagnostic Procedures

2. INSPECT CLUTCH SWITCH

(a) Turn the ignition switch OFF.





(b) Disconnect the A3 clutch switch connector.

(c) Remove the clutch switch. Removal

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

Standard resistance:





(e) Install the clutch switch.

(f) Reconnect the clutch switch connector.

NG -- REPLACE CLUTCH SWITCH Removal
OK -- Continue to next step.

3. CHECK HARNESS AND CONNECTOR (ECM - CLUTCH SWITCH)

(a) Disconnect the B33 ECM connector.

(b) Disconnect the A3 clutch switch connector.

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





Standard resistance:





(d) Reconnect the ECM connector.

(e) Reconnect the clutch switch connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR (BATTERY - CLUTCH SWITCH)
