P0830 Clutch Pedal Switch ''A'' Circuit

P0830 code - This diagnostic runs continuously while driving the vehicle and shifting gears. The Powertrain Control Module (PCM) does not detect changes in the clutch interlock switch signal circuit voltage or the clutch upstop signal circuit voltage while CAN messages from the Transmission Control Module indicate transmission gear changes. Default action the MIL light will illuminate.

Possible causes P0830 code

- Clutch interlock switch signal circuit shorted to ground
- Clutch upstop signal circuit shorted to ground
- Clutch interlock switch signal circuit open/high resistance
- Clutch upstop signal circuit open/high resistance
- Ground circuit open/high resistance
- Clutch switch
- Powertrain Control Module (PCM)

Diagnostic test P0830 code

Step 1. Check for an active DTC
Turn the ignition on, with the scan tool erase DTCs in the PCM. Press and release the clutch pedal several times, with the scan tool read DTCs.

Is the DTC active or pending?

Yes, go to step 2.
No, perform the PCM intermittent condition.

Step 2. Check the clutch interlock switch signal circuit voltage
Turn the ignition off, disconnect the clutch interlock switch harness connector. Turn the ignition on, measure the voltage on the clutch interlock switch signal circuit in the clutch interlock switch harness connector.

Is the voltage above 10.0 volts?

Yes, go to step 3.
No, go to step 5.

Step 3. Check the ground circuit for an open/high resistance
Using a 12-volt test light connected to 12 volts, probe the ground at the clutch interlock switch harness connector. Test light should be illuminated and bright. Compare the brightness to that of direct connection to the battery.

Is the test light illuminated and bright?

Yes, go to step 4.
No, repair the ground for an open or high resistance.

Step 4. Check the clutch interlock switch
Turn the ignition off, connect a jumper between the ground circuit and the clutch interlock switch signal circuit at the clutch interlock switch harness connector. Turn the ignition on, with the scan tool monitor the clutch interlock status. The scan tool should display the clutch interlock status as pressed with the jumper in place and not pressed with the jumper removed.

Does the scan tool display the status as described above?

Yes, replace the clutch interlock switch.
No, go to step 5.

Step 5. Check the clutch interlock switch signal circuit for a short to ground
Turn the ignition off, disconnect the PCM harness connector. check for continuity between ground and the clutch interlock switch signal circuit at the clutch interlock switch harness connector.

Is there continuity between ground and the clutch interlock switch signal circuit?

Yes, repair the clutch interlock switch signal circuit for a short to ground.
No, go to step 6.

Step 6. Check the clutch upstop switch signal circuit for a short to ground
Turn the ignition off, disconnect the clutch switch harness connector. Check for continuity between ground and the clutch upstop switch signal circuit at the clutch switch harness connector.

Is there continuity between ground and the clutch upstop switch signal circuit?

Yes, repair the clutch upstop switch signal circuit for a short to ground.
No, go to step 7.

Step 7. Check the clutch interlock switch signal circuit for an open/high resistance
Measure the resistance of the clutch interlock switch signal circuit between the clutch interlock switch harness connector and PCM harness connector.

Is the resistance below 3.0 Ohms?

Yes, go to step 8.
No, repair the clutch interlock switch signal circuit for an open or high resistance.

Step 8. Check the clutch upstop switch signal circuit for an open/high resistance
Measure the resistance of the clutch upstop switch signal circuit between the clutch switch harness connector and the PCM harness connector.

Is the resistance below 3.0 Ohms?

Yes, go to step 9.
No, repair the slutch upstop switch signal circuit for an open or high resistance.

Step 9. Check related PCM and component connections
