- Ignition ON.
- Retrieve the IPC DTCs.
- Is DTC B10D7:87 retrieved?
- Yes : GO to B2.
- No : If any other IPC DTCs are retrieved, REFER to MULTIFUNCTION ELECTRONIC MODULES .
  If no DTCs are retrieved, the system is OK. The concern may have been caused by an intermittent concern with the key, the transceiver or the IPC.
B2 CHECK BOTH PATS KEYS
- Obtain both PATS keys from the customer and follow the procedure using one PATS key, then the other. If the customer only has one PATS key, it is necessary to cut a new PATS key.
- If it is necessary to cut a new PATS key, program the new PATS key. Refer to INTEGRATED KEYHEAD TRANSMITTER (IKT) KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT .
- Ignition ON.
- Clear the IPC DTCs.
- Ignition OFF.
- Ignition ON.
- Retrieve the IPC DTCs.
- Using all existing keys, then the newly programmed key (if applicable), is DTC B10D7:87 present?
- Yes : If DTC B10D7:87 was present for both keys or the new key (if present), GO to B3.
  If DTC B10D7:87 was present for the new key, the original key may be damaged and should be replaced. REPLACE the damaged key with a new key. REFER to INTEGRATED KEYHEAD TRANSMITTER (IKT) KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT . CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test. TEST the system for normal operation.
- No : If any other IPC DTCs are retrieved, REFER to MULTIFUNCTION ELECTRONIC MODULES .
  If no IPC DTCs are retrieved, the system is OK. The concern may have been caused by an intermittent concern with the key, the transceiver or the IPC.
B3 INSTALL A NEW PATS TRANSCEIVER
NOTE: Replacement of the PATS transceiver does not require the PATS keys to be programmed into the IPC again.

- Operate the system and verify the concern is still present.
- Is the concern still present?
- Yes : INSTALL a new IPC. REFER to INSTRUMENTATION, MESSAGE CENTER, AND WARNING CHIMES . RESET the parameters. REFER to PASSIVE ANTI-THEFT SYSTEM (PATS) PARAMETER RESET . PROGRAM the PATS keys into the new IPC. REFER to INTEGRATED KEYHEAD TRANSMITTER (IKT) KEY PROGRAMMING USING DIAGNOSTIC EQUIPMENT . CYCLE the ignition. REPEAT the self-test.
- No : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. CLEAR the DTCs. CYCLE the ignition. REPEAT the self-test.
