Clutch Switch Circuit

CRUISE CONTROL SYSTEM: Clutch Switch Circuit

Clutch Switch Circuit

DESCRIPTION

Clutch switch circuit inspection is necessary for M/T vehicles.
When the clutch pedal is released, the ECM receives the positive (+) battery voltage through the IG1 No.2 fuse and ignition switch. While the clutch pedal is depressed, the clutch switch assembly sends a signal to terminal D of the ECM. The ECM cancels cruise control when terminal D receives the signal (voltage of below 1 V).

INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (ECM - BATTERY)





(a) Turn the ignition switch OFF.
(b) Disconnect the E7 ECM connector.
(c) Turn the ignition switch to the ON position.
(d) Measure the voltage according to the value(s) in the table below.
Standard Voltage:





(e) Reconnect the ECM connector.
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
NG -- Continue to next step.
2. INSPECT CLUTCH SWITCH ASSEMBLY





(a) Turn the ignition switch off.
(b) Disconnect the clutch switch C14 connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:





(d) Reconnect the clutch switch connector.
NG -- REPLACE CLUTCH SWITCH ASSEMBLY
OK -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (CLUTCH SWITCH ASSEMBLY - BODY GROUND)





(a) Disconnect the E7 ECM connector.
(b) Disconnect the C14 clutch switch connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:





(d) Reconnect the clutch switch connector.
(e) Reconnect the ECM connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (CLUTCH SWITCH ASSEMBLY - ECM)
OK -- CHECK AND REPAIR HARNESS OR CONNECTOR (CLUTCH SWITCH ASSEMBLY - BATTERY)
