Test Procedure

  1. QA1 CARRY OUT A VEHICLE INSPECTION AND VERIFY THE SELF-TEST PROCEDURE 
    NOTE: For DTC U0284, GO to  QA15.
    NOTE: If the self-test or communication concern occurred after a failed or aborted reprogram, the module may be blank. Attempt to reprogram the module again before continuing with this pinpoint test.
    • Visually inspect the following for obvious signs of electrical damage:
      • harness wiring
      • electrical connections
    • Verify the correct procedure was used to activate the self-test for the scan tool. Refer to SCAN TOOL SET-UP AND FUNCTIONALITY .

    Was the correct self-test procedure used? 

    Yes No
    GO to QA2  . REFER to DIAGNOSTIC METHODS, SCAN TOOL SET-UP AND FUNCTIONALITY , to continue diagnosis.
  2. QA2 CARRY OUT THE NETWORK TEST 
    NOTE: When using Integrated Diagnostic System (IDS), the scan tool attempts to communicate with the PCM first. After establishing communication with the PCM, the scan tool then attempts to communicate with all modules on the vehicle. If an IDS session cannot be established, IDS may state no communication can be established with the PCM:
    • Choose No when the scan tool prompts whether or not to retry communication.
    • Enter a PCM part number, tear tag or calibration number to identify the vehicle and start a session. The PCM part number and 4-character tear tag are located on the PCM.
    • Ignition ON, engine OFF.
    • Carry out the network test.

    Do all modules indicate pass? 

    Yes No
    For DTC U0104, GO to  QA11.
    For DTC U0151, GO to  QA13.
    For DTC U0155, GO to  QA10.

    For DTCs U0101, U0293, U0402 or U1010, GO to  QA7.
    For all others, RETURN to ENGINE CONTROLS - SYMPTOM CHARTS (HYBRID) for further direction.    		 If only the PCM indicates fail, GO to QA3  .
    For network test or all other modules indicates fail, REFER to the Module Communications Network article, Communication Network Symptom Chart, to continue diagnosis.

    Are the voltages greater than 10.5V? 

    Yes No
    GO to QA6  . GO to PINPOINT TEST B .
  6. QA6 CHECK THE PWRGND CIRCUITS FOR AN OPEN 
    • Ignition OFF.
    • Measure the resistance between:
      (+) PCM Connector, Harness Side (-)
      PWRGND - Pin B35, B36, B47, B48, T31 Ground

    Are the resistances less than 5 ohms?
