Clutch Switch Circuit

DESCRIPTION

Clutch switch circuit inspection is necessary for manual transmission 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) Disconnect the E9 or E7 ECM connector.
(b) Turn the ignition switch to the ON position.
(c) Measure the voltage according to the value(s) in the table below.
Standard Voltage:





- *1: for 1GR-FE
- *2: for 2TR-FE
(d) Reconnect the ECM connector.
OK -- PROCEED TO PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE
NG -- Continue to next step.

2. INSPECT CLUTCH SWITCH ASSEMBLY




(a) Remove the clutch switch Removal.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:





(c) Reinstall the clutch switch.
NG -- REPLACE CLUTCH SWITCH ASSEMBLY
OK -- Continue to next step.

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




(a) Disconnect the E7 or E9 ECM connector.
(b) Disconnect the C14 clutch switch connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:





- *1: for 1GR-FE
- *2: for 2TR-FE
(d) Reconnect the clutch switch connector.
(e) Reconnect the ECM connector.
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR (CLUTCH SWITCH ASSEMBLY - ECM)
OK -- REPAIR OR REPLACE HARNESS OR CONNECTOR (CLUTCH SWITCH ASSEMBLY - BATTERY)
