TEST PROCEDURE

During ECU flash reprogramming, the Error screen at right may be displayed on the Diagnostic Tester for one of the following reasons: See Fig 1.

Fig 1: Error Message

  1. Immobilizer key not properly registered or auto-registration mode left open.
  2. Ignition ON/OFF cycling not followed correctly during the flash reprogramming procedure.
  3. The Diagnostic Tester cable is damaged, causing an open communication circuit.
NOTE: The Diagnostic Tester may operate properly in other modes such as OBD, OBDII, or CARB, with a damaged cable.

To eliminate the possibility of the first 2 reasons causing the error message, do the following:

  1. Confirm the Immobilizer Transponder Master Key is properly registered and auto registration mode is closed. Follow the appropriate Repair Manual procedure and consult TSB SS001-99 - SCANTOOL IMMOBILIZER KEY CODE UTILITY.
  2. Conduct the ECU flash reprogramming process explicitly following key operation instructions. Refer to TSB SS002-01 - ECU FLASH REPROGRAMMING PROCESS, for more details.

    To determine if the Diagnostic Tester cable is damaged, follow the test procedures below to check the electrical integrity of the cable. Conduct all continuity tests with an Ohm meter. For all five test procedures, the resistance values must be below 6.0 ohms to pass. See Fig 2.

CABLE TEST 1

  1. Connect Diagnostic Tester cables DLC (P/N 02001637) and CAN Interface Module / J1962 OBDII together (P/N 01002744). See Fig 3.

  2. Test for continuity.
    • If there is continuity, the cable is OK. Check steps 1 and 2 above to complete the flash reprogramming process.
    • If there is no continuity, proceed to CABLE TEST 2.

CABLE TEST 2

  1. Disconnect Diagnostic Tester cables DLC (P/N 02001637) and CAN Interface Module / J1962 OBDII (P/N 01002744). See Fig 4.

  2. Test DLC cable (P/N 02001637) for continuity.
    • If there is continuity, the cable is OK. Proceed to CABLE TEST 3.
    • If there is no continuity, the cable needs to be replaced.

CABLE TEST 3

  1. Test J1962 OBDII / CAN Interface Module (P/N 01002744) for continuity. See Fig 5.

    • If there is continuity, the cable and CAN Interface Module are OK. Re-check Cable Tests 1, 2, and 3 while wiggling and flexing the cables.
    • If there is no continuity, proceed to CABLE TEST 4.

CABLE TEST 4

  1. Disconnect the CAN Interface Module (P/N 01002744) from the J1962 OBDII cable using a Phillips screwdriver. See Fig 6.

  2. Test J1962 OBDII cable (P/N 02003180) for continuity.
    • If there is no continuity, the cable needs to be replaced.
    • If there is continuity, proceed to CAN Interface Module Test 5.

CAN INTERFACE MODULE TEST 5

  1. Test the CAN Interface Module (P/N 01002744) for continuity. See Fig 7.
