Pass-Key(R) III System Auto Learn Procedure
NOTE:
PASS-Key(R) III system auto learn procedure must be performed if all keys are lost, or Powertrain Control Module (PCM), PASS-Key(R) III module, ignition lock cylinder, steering column assembly or ignition key are replaced. A password is communicated between PASS-Key(R) III module and PCM to provide engine operation. If PCM is replaced, the PCM must learn password from PASS-Key(R) III module.
