Clutch Switch Circuit

DESCRIPTION

Clutch switch circuit inspection is necessary for M/T vehicles.
When the clutch pedal is released, the ECM receives positive (+) battery voltage through the ECU-IG No. 1 fuse. While depressing the clutch pedal, the clutch switch sends a signal to terminal D of the ECM. The ECM cancels cruise control when terminal D receives the signal.

INSPECTION PROCEDURE

PROCEDURE

1. INSPECT ECM




(a) Disconnect the B31 connector from the ECM.
(b) Turn the ignition switch to ON.
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:






NG -- INSPECT CLUTCH SWITCH ASSEMBLY
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
2. INSPECT CLUTCH SWITCH ASSEMBLY
(a) Turn the ignition switch off.
(b) Disconnect the A4 connector from the clutch switch assembly.




(c) Remove the clutch switch assembly Components.
(d) Measure the resistance according to the value(s) in the table below.
Standard Resistance:






NG -- REPLACE CLUTCH SWITCH ASSEMBLY
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (ECM - CLUTCH SWITCH ASSEMBLY)




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






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