  1. Turn ignition switch to LOCK position. Connect NGS tester to Data Link Connector (DLC), located under instrument panel next to steering column. Using NGS tester, retrieve and record continuous DTCs. Clear continuous DTCs and perform instrument cluster self-test. If DTC B2139 is retrieved, go to next step. If DTC B2139 is not retrieved, system is okay at this time.

If DTC B2139 is not retrieved, system is okay at this time. If DTC B2139 is retrieved, verify PCM calibration is correct for vehicle. If calibration is okay, go to next step.
  3. Repeat step 2). If DTC B2139 is still exists, replace instrument cluster. If DTC B2139 does not exist, system is okay at this time. If any other DTCs are retrieved, perform appropriate test.

NOTE: This procedure is used when a customer needs keys programmed into system and does not have 2 programmed ignition keys available, or when programmed ignition keys have been lost and/or ignition switch assembly has been replaced. This procedure will erase all programmed ignition keys from memory and prevent vehicle from starting until 2 keys have been programmed. Ignition keys must have correct mechanical key cut for vehicle and must be an encoded key. If additional key(s) are to be programmed, perform KEY PROGRAMMING - USING 2 PROGRAMMED KEYS. If remaining keys are with customer and not with vehicle, instruct customer to see owner's manual to program spare key(s).
