Cruise Control

Pinpoint Test E: DTC P0833

Normal Operation

Vehicles equipped with a manual transaxle have an additional clutch pedal cruise control deactivator switch. The clutch pedal cruise control deactivator switch is a normally open switch with the clutch pedal released. When the clutch pedal is pressed, the clutch pedal cruise control deactivator switch moves to the closed position, which routes the ground signal to the Instrument Panel Cluster (IPC). The IPC (Instrument Panel Cluster) sends a network message over the High Speed Controller Area Network (HS-CAN) to the PCM, deactivating the cruise control system.

- DTC P0833 (Clutch Pedal Switch B Circuit)- this is a logic based DTC that sets when the PCM receives the vehicle speed input, indicating vehicle movement and does not detect the switching input signal from the Clutch Pedal Position (CPP) switch or clutch pedal cruise control deactivator switch. This condition disables cruise control.

This pinpoint test is intended to diagnose the following:

- Wiring, terminals or connectors

- PCM

PINPOINT TEST E : DTC P0833

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

E1 CHECK THE CLUTCH PEDAL PIDs

- Ignition ON.

- Enter the following diagnostic mode on the scan tool: PCM DataLogger.

- Monitor the PCM PID CPP_TOP and CPP_BOT while pressing and releasing the clutch pedal.

Does the PID values agree with the clutch pedal position?

Yes
GO to E2.

No
For an incorrect CPP_TOP PID GO to Pinpoint Test D Pinpoint Test D: The Cruise Control Does Not Disengage When The Clutch Pedal Is Pressed.

For an incorrect CPP_BOT PID Starting System to diagnose the CPP (Clutch Pedal Position) switch.

E2 CHECK FOR CORRECT PCM OPERATION

- Connect: All Disconnected Connectors.

- Disconnect all the PCM connectors.

- Check for:
- corrosion

- damaged pins

- pushed-out pins


- Connect all the PCM connectors and make sure they seat correctly.

- Operate the system and verify the concern is still present.

Is the concern still present?

Yes
INSTALL a new PCM.

No
The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
