P0830-CLUTCH PEDAL SWITCH CIRCUIT

For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
While driving the vehicle and shifting gears.

- Set Condition:
The Powertrain Control Module (PCM) does not detect changes in the (T141) Clutch Interlock Switch Signal circuit voltage while CAN messages from the Transmission Control Module indicate transmission gear changes.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure.

1. DTC IS ACTIVE
1. Ignition on, engine not running.
2. With the scan tool, clear DTCs in the PCM.
3. Press and release the clutch pedal several times.
4. With the scan tool, select View DTCs.

Is the status Active for this DTC?

Yes

- Go To 2

No

- Perform the INTERMITTENT DTC diagnostic procedure. .

2. CHECK THE (T141) CLUTCH INTERLOCK SWITCH SIGNAL CIRCUIT VOLTAGE
1. Turn the ignition off.
2. Disconnect the Clutch Interlock Switch harness connector.
3. Turn the ignition on.
4. Measure the voltage of the (T141) Clutch Interlock Switch Signal circuit in the Clutch Interlock Switch harness connector.

Is the voltage above 10.0 Volts?

Yes

- Go To 3

No

- Go To 5

3. CHECK THE (Z905) GROUND CIRCUIT FOR AN OPEN/HIGH RESISTANCE
1. Using a 12-volt test light connected to 12 Volts, check the (Z905) Ground circuit in the Clutch Interlock Switch harness connector.

NOTE: The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.

Is the test light illuminated and bright?

Yes

- Go To 4

No

- Repair the (Z905) Ground for an open or high resistance.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

4. CHECK THE CLUTCH INTERLOCK SWITCH
1. Turn the ignition off.
2. Connect a jumper wire between the (Z904) Ground circuit and the (T141) Clutch Interlock Switch Signal circuit in the Clutch Interlock Switch harness connector.
3. Turn the ignition on.
4. With the scan tool, monitor the Clutch Interlock status.

NOTE: The scan tool should display the Clutch Interlock status as pressed with the jumper wire in place and not pressed with the jumper wire removed.

Does the scan tool display the status as described above?

Yes

- Replace the Clutch Interlock Switch.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

No

- Go To 7

5. CHECK THE (T141) CLUTCH INTERLOCK SWITCH SIGNAL CIRCUIT FOR A SHORT TO GROUND
1. Turn the ignition off.
2. Remove the jumper.
3. Reinstall the ASD Relay.
4. Measure the resistance between ground and the (T141) Clutch Interlock Switch Signal circuit in the Clutch Interlock Switch harness connector.

Is the resistance above 10k Ohms?

Yes

- Go To 6

No

- Repair the (T141) Clutch Interlock Switch Signal circuit for a short to ground.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

6. CHECK THE (T141) CLUTCH INTERLOCK SWITCH SIGNAL CIRCUIT FOR AN OPEN/HIGH RESISTANCE
1. Measure the resistance of the (T141) Clutch Interlock Switch Signal circuit between the Clutch Interlock Switch harness connector and the PCM C2 harness connector.

Is the resistance below 5.0 Ohms?

Yes

- Go To 7

No

- Repair the (T141) Clutch Interlock Switch Signal circuit for an open or high resistance.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

7. POWERTRAIN CONTROL MODULE
1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Clutch Interlock Switch and the Powertrain Control Module (PCM).
2. Look for any chafed, pierced, pinched or partially broken wires.
3. Look for broken, bent, pushed out or corroded terminals.
4. Perform any Technical Service Bulletins that may apply.

Were any problems found?

Yes

- Repair as necessary.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.

No

- Replace the Powertrain Control Module.
- Perform the POWERTRAIN VERIFICATION TEST. Powertrain Verification Test.
