Lock Cylinder & Harness Test

  1. Insert ignition key into PASS-Key II(R) Interrogator (J 35628-A). Turn interrogator on. Read key code shown on interrogator display. If display is 1 through 15, go to next step. If display is "E" for error, clean and retest key. If key code is invalid, replace key.
  2. Record displayed key code. Turn interrogator off. Connect interrogator to 2-pin ignition switch lock cylinder harness connector at base of steering column. Insert ignition key into ignition switch lock cylinder. Turn interrogator on. While observing display on interrogator, turn ignition switch slowly to START position. Check if displayed key code matches value recorded earlier.
    NOTE: Both wires of 2-pin ignition switch lock cylinder harness connector at base of steering column are White. When probing 2-pin connector, check for wire color at Body Control Module (BCM) side of connector.
  3. If displayed code does not match value recorded earlier, check for poor connection at ignition switch lock cylinder. If connection is okay, replace ignition switch lock cylinder and harness. If displayed code matches value recorded earlier, connect test light between battery voltage and terminal "B" (Purple/White wire) of 2-pin ignition switch lock cylinder harness connector at base of steering column. If test light illuminates, go to step 5). If test light does not illuminate, go to next step.
  4. Disconnect BCM 32-pin connector C3 (Blue). Connect test light between BCM connector C3, terminal C1 (Black wire) and battery voltage. If test light does not illuminate, repair open in Black wire. If test light illuminates, check for poor connection at BCM or for open in Purple/White wire. If connection and Purple/White wire are okay, replace BCM.
  5. Disconnect BCM 32-pin connector C3 (Blue). Turn ignition switch to RUN position. Connect test light between terminals "A" (White/Black wire) and "B" (Purple/White wire) of 2-pin ignition switch lock cylinder harness connector (module side) at base of steering column. If test light illuminates, repair short to voltage in White/Black wire. If test light does not illuminate, check for an open or short to ground in White/Black wire. If White/Black wire is okay, replace BCM.
