Clutch Pedal Safety Switch | Applied/Released | Applied | Released | -- |
Circuit/System Description
The clutch safety switch is a normally open switch. When the ignition is ON, the engine control module (ECM) supplies B+ on the signal circuit to the clutch safety switch. A wire from the clutch safety switch to chassis ground completes the electrical circuit. The ECM senses B+ on the signal circuit with the clutch pedal released, and zero volts with the clutch pedal depressed.
Conditions for Running the DTC
| • | The ignition is ON. |
| • | DTC P0500 is not set. |
Conditions for Setting the DTC
The ECM detects changes in vehicle greater than 38 km/h (24 mph) without the ECM detecting a clutch pedal transition.
Action Taken When the DTC Sets
DTC P0833 is a Type B DTC.
Conditions for Clearing the DTC
DTC P0833 is a Type B DTC.
Diagnostic Aids
This test procedure requires that the battery is completely charged. Refer to Battery Inspection/Test.

Circuit/System Verification
- Start the engine, with the clutch pedal depressed. The engine should start and run.
- Operate the vehicle within the conditions for running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records.
Circuit/System Testing
- Ignition OFF, disconnect the clutch safety switch harness connector.
- Test for less than 5 ohms between the clutch safety switch harness connector terminal B and the negative battery post.
- Ignition ON, test for 11-13 volts on the clutch safety switch harness connector terminal A and ground.
- If all circuits test normal, replace the clutch safety switch.
| ⇒ | If greater than the specified range, test the ground circuit for an open/high resistance. |
| ⇒ | If not within the specified range, test the signal circuit for a short to ground, or an open/high resistance. If the circuit tests normal, replace the ECM. |
Component Testing
- Ignition OFF, disconnect the clutch safety switch harness connector.
- Test for less than 5 ohms between terminals A and B on the clutch safety switch.
| ⇒ | If greater than the specified value, replace the clutch safety switch. |
Repair Verification
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
