TRANSPONDER

1. Clear DTCs and rerun On-Demand Self-Test. If DTC B1601 is present, go to next step. If DTC B1601 is not present, system is operating normally.
2. Using a existing and a new encoded key, program new key. See SPARE KEY PROGRAMMING  . If THEFT indicator light turns on for 2 seconds and engine will start, replace damaged encoded key and retest system. If THEFT indicator light does not turn on for 2 seconds and engine will not start, go to next step.
3. Set aside original encoded ignition keys. Using one new key, perform key initialization. See KEY INITIALIZATION  . Using newly encoded key, attempt to start engine. If engine starts and keeps running, replace original encoded ignition key with newly programmed key. Program a spare key if necessary. See SPARE KEY PROGRAMMING  . Retest system. If engine will not start, replace PATS transceiver module and retest system.
