Possible Causes

• Wiring, terminals or connectors
• Clutch pedal switch
• Network communication concern
• PCM

Visual Inspection and Diagnostic Pre-checks 

• Make sure the clutch pedal switch electrical connector is connected and free of corrosion and other contaminants.
• Make sure the clutch pedal switch is installed correctly.
• Make sure the clutch pedal switch operates correctly.

1. BO1: CHECK THE CLUTCH PEDAL SWITCH AND CLUTCH PEDAL ASSEMBLY INSTALLATION 
   • Inspect the clutch pedal switch and brake pedal assembly. Verify the clutch pedal is not unintentionally applied due to incorrect clutch pedal switch or clutch pedal installation.
     • To verify clutch pedal switch (cruise control deactivator switch) installation, refer to the Cruise Control article.
     • To verify clutch pedal installation, refer to the appropriate Manual Transmission article.
   • Are the clutch pedal switch and clutch pedal assembly installed correctly? 

   Yes	No
   Go to  BO2.	REINSTALL the clutch pedal switch or clutch pedal assembly correctly. REFER to the appropriate Manual Transmission article or Cruise Control article.

2. BO2: CHECK THE PCM BPP (BOO1) PID 
   • Ignition ON, engine OFF.
   • Using a diagnostic scan tool, monitor the PCM clutch pedal PID.
   • Apply and release the clutch pedal.
   • Does the PID reflect the clutch pedal movement? 

   Yes	No
   Go to  BO3.	DIAGNOSE the clutch pedal switch (also known as the cruise control deactivator switch). REFER to the Cruise Control article.

3. BO3: CHECK FOR ABS MODULE DTCS 

   Carry out the ABS self-test.

   • Is DTC U0100:00 or U0401:00 present in the ABS module? 

   Yes	No
   For DTC U0401:00, GO to the ABS module DTC Chart. For DTC U0100:00, GO to PINPOINT TEST AI .	Go to  BO4.

4. BO4: CHECK THE PCM FOR DTCS 

   Carry out the PCM KOEO self-test.

   • Are any DTCs present? 

   Yes	No
   DIAGNOSE the PCM DTC. REFER to the appropriate Electronic Engine Controls article.	Go to  BO5.

5. BO5: VERIFY ALL WIRING CONNECTIONS 
   • Ignition OFF.
   • ABS Module connector disconnected. (C135)
   • PCM_E connector disconnected.
   • Disconnect the clutch pedal switch electrical connector.
   • Disconnect all in-line electrical connectors between the ABS module, the PCM and the clutch pedal switch.
   • Using a good light source, inspect all disconnected electrical connectors for the following:
     • corrosion - install new connector or terminal and clean the module pins
     • damaged or bent pins - install new terminals or pins
     • pushed-out pins - install new pins as necessary
     • spread terminals - install new terminals as necessary
   • Are the connectors free of corrosion, damaged pins, bent pins, pushed-out pins and spread terminals? 

   Yes	No
   Go to  BO6.	REPAIR the connector or terminals. Refer to OEM Connector Repair Procedures article, for schematic and connector information.

6. BO6: CHECK FOR CORRECT PCM OPERATION 
   • Connect all in-line electrical connectors between the ABS module, the PCM and the clutch pedal switch.

     Make sure the connectors seat and latch correctly.

   • Connect the clutch pedal switch electrical connector. Make sure the connector seats and latches correctly.
   • PCM_E connector connected. Make sure the connector seats and latches correctly.
   • ABS Module connector connected. (C135) Make sure the connector seats and latches correctly.
   • Operate the system and determine if the concern is still present.
   • Is the concern still present? 

   Yes	No
   INSTALL a new PCM. CHECK OASIS for any applicable Technical Service Bulletins TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions. If no TSBs address this concern, INSTALL a new PCM. REFER to the appropriate Electronic Engine Controls article.	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or pin issues.
