- INSPECT ECM
- Disconnect the ECM connector.
- Turn the ignition switch to ON.
- Measure the voltage according to the value(s) in the table below.
Standard Resistance (2AZ-FE)
Tester Connection Condition Specified Condition B31-56 (D) - Body ground Clutch pedal depressed Below 1 V Clutch pedal released 11 to 14 V Standard Resistance (2GR-FE)
Tester Connection Condition Specified Condition B31-47 (D) - Body ground Clutch pedal depressed Below 1 V Clutch pedal released 11 to 14 V - Reconnect the ECM connector.
NG → See step 2
OK → See step 4
- INSPECT CLUTCH SWITCH ASSEMBLY
- Turn the ignition switch off.
- Remove the clutch switch assembly. Refer to COMPONENTS .
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Switch Condition Specified Condition 1 - 2 Switch pin free 10 kΩ or higher Switch pin pushed in Below 1 Ω - Install the clutch switch assembly. Refer to INSTALLATION .
NG → See step 5
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (ECM - CLUTCH SWITCH ASSEMBLY)
- Measure the resistance according to the value(s) in the table below.
Standard Resistance (2AZ-FE)
Tester Connection Condition Specified Condition B31-56 (D) - A4-2 Always Below 1 Ω B31-56 (D) - Body ground Always 10 kΩ or higher Standard Resistance (2ZR-FE)
Tester Connection Condition Specified Condition B31-47 (D) - A4-2 Always Below 1 Ω B31-47 (D) - Body ground Always 10 kΩ or higher
NG → REPAIR OR REPLACE HARNESS OR CONNECTOR (ECM - CLUTCH SWITCH ASSEMBLY)
OK → REPAIR OR REPLACE HARNESS OR CONNECTOR (BATTERY - CLUTCH SWITCH ASSEMBLY)
- Measure the resistance according to the value(s) in the table below.
- PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE. Refer to PROBLEM SYMPTOMS TABLE
- REPLACE CLUTCH SWITCH ASSEMBLY. Refer to COMPONENTS
