Immobilizer-Keyless Control Unit or ECM/PCM Cannot Be Rewritten (Supersedes 06-008, dated March 2, 2006, to update the information marked by
asterisks)
SYMPTOM
The immobilizer system can't be rewritten after replacing the ECM/PCM or the immobilizer-keyless control unit.
VEHICLES AFFECTED
PROBABLE CAUSE
The gauge control module (tachometer) does not contain the supporting data for immobilizer reprogramming that allows you to rewrite it.
CORRECTIVE ACTION
*Replace the gauge control module (tachometer) if you replace the ECM/PCM or the immobilizer-keyless control unit.*
NOTE:
You must transfer the odometer mileage from the old gauge control module to the new gauge control module.
PARTS INFORMATION
*NOTE:
Because ECM/PCM and immobilizer-keyless control unit replacements are rare, it is not necessary to stock the gauge control module (tach).*
