Clutch Switch Circuit

DESCRIPTION

Clutch switch circuit inspection is necessary for manual transaxle vehicles.
When the clutch pedal is released, the ECM receives battery voltage through the IG1 relay and ECU-IG fuse. When the clutch pedal is depressed, the clutch switch for the cruise control opens, and voltage is no longer sent to terminal D of the ECM. The ECM cancels cruise control operation when the battery voltage to terminal D is interrupted.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK WIRE HARNESS (ECM - BATTERY)




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





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




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





(c) Reconnect the clutch switch connector.
NG -- REPLACE CLUTCH SWITCH ASSEMBLY
OK -- Continue to next step.
3. CHECK WIRE HARNESS (CLUTCH SWITCH - ECM)




(a) Disconnect the clutch switch connector.
(b) Disconnect the ECM 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 (CLUTCH SWITCH - BATTERY)
