Diagnostic Test

  1. 1) PRE-DIAGNOSTIC CHECK OUT 
    NOTE: Always perform diagnostics with a fully charged battery.
    NOTE: Check connectors - Clean/repair as necessary. Poor pin to terminal connections can set DTCs.
    NOTE: Check for applicable TSBs related to the problem.

    Turn the ignition on.

    With the scan tool, read PCM DTCs.

    Using the wiring diagram/schematic as a guide, inspect the wiring and connectors. Repair as necessary.

    Perform this procedure prior to symptom diagnosis. 

    Continue 

    1. Go to  2).
  2. 2) CHECK FOR CURRENT DTC 
    WARNING: WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.
    NOTE: If the PCM detects and stores a DTC, the PCM also stores the engine/vehicle operating conditions under which the DTC was set. Some of these conditions are displayed on the scan tool at the same time the DTC is displayed.
    NOTE: Before erasing stored DTCs, record these conditions. Attempting to duplicate these conditions may assist when checking for a DTC.

    Turn the ignition on.

    With the scan tool, erase PCM DTCs.

    NOTE: It maybe necessary to road test the vehicle for this DTC to set.
