2008 Hyundai Azera GLSFACTORY OEM SERVICE PROCEDURE

Pcm Problem Inspection Procedure

  1. TEST PCM GROUND CIRCUIT: Measure resistance between PCM and chassis ground using the backside of PCM harness connector as PCM side check point. If the problem is found, repair it.

    Specification (Resistance): 1Ξ© or less

  2. TEST PCM CONNECTOR: Disconnect the PCM connector and visually check the ground terminals on PCM side and harness side for bent pins or poor contact pressure. If the problem is found, repair it.
  3. If problem is not found in Step Β 1 and Β 2, the PCM could be faulty. If so, replace the PCM with a new one, and then check the vehicle again. If the vehicle operates normally then the problem was likely with the PCM.
  4. RE-TEST THE ORIGINAL PCM: Install the original PCM (may be broken) into a known-good vehicle and check the vehicle. If the problem occurs again, replace the original PCM with a new one. If problem does not occur, this is intermittent problem (Refer to INTERMITTENT PROBLEM PROCEDUREΒ  in BASIC INSPECTION PROCEDURE).

VIN PROGRAMMING PROCEDUREΒ 

VIN (Vehicle Identification Number) is a number that has the vehicle's information (Maker, Vehicle Type, Vehicle Line/Series, Body Type, Engine Type, Transmission Type, Model Year, Plant Location and so forth. For more information, please refer to the GENERAL INFORMATION article ). When replacing a PCM, the VIN must be programmed in the PCM. If there is no VIN in PCM memory, the fault code (DTC P0630) is set.

CAUTION: The programmed VIN cannot be changed. When writing the VIN, confirm the VIN carefully
  1. Select "Vehicle" and "Engine" (For example, TUCSON 2.0L L4).
