INSPECTION PROCEDURE
INSPECT ECM (CLSW TERMINAL)
INSPECT CLUTCH SWITCH
CHECK HARNESS AND CONNECTOR (ECM - CLUTCH SWITCH)
CRUISE CONTROL SYSTEM - 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 LH-IG fuse. While depressing the clutch pedal, the clutch switch sends a signal to terminal CLSW of the ECM. The ECM cancels cruise control drive when terminal CLSW receives the signal.

INSPECTION PROCEDURE
| 1.INSPECT ECM (CLSW TERMINAL) |
Disconnect the A49 connector from the ECM.
Turn the engine switch on (IG).
Measure the voltage according to the value(s) in the table below.
- Standard voltage:
| Tester Connection | Condition | Specified Condition |
| A49-42 (CLSW) - Body ground | Clutch pedal depressed | Below 1 V |
| Clutch pedal released | 10 to 14 V |
| | PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE |
|
|
Turn the engine switch off.
Disconnect the A21 connector from the clutch switch.
Remove the clutch switch .
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
| Tester Connection | Condition | Specified Condition |
| 1 - 2 | Switch pin free
(Clutch pedal depressed) | 10 kΩ or higher |
Switch pin pushed in
(Clutch pedal released) | Below 1 Ω |
| 3.CHECK HARNESS AND CONNECTOR (ECM - CLUTCH SWITCH) |
Measure the resistance according to the value(s) in the table below.
- Standard resistance:
| Tester Connection | Condition | Specified Condition |
| A49-42 (CLSW) - A21-2 | Always | Below 1 Ω |
| A49-42 (CLSW) - Body ground | Always | 10 kΩ or higher |
| | REPAIR OR REPLACE HARNESS OR CONNECTOR |
