## NHTSA's summary

Flash: Unable to Program Keys After Wireless Control Module Replacement and/or Malfunction Indicator Lamp \(MIL\) Illumination This bulletin involves selectively erasing and reprogramming the Powertrain Control Module \(PCM\) with new software. Technicians may find that the original vehicle keys/FOBIKs do not function properly following replacement of the Wireless Control Module\(WCM\). The Secret Key information stored in the PCM may be corrupt. This update will restore the PCM?s ability to store/transfer valid Secret Key information.A small number of customers may also experience a Malfunction Indicator Lamp \(MIL\) illumination. Upon further investigation the Technician may find that the following Diagnostic Trouble Code \(DTC\) has been set: P0606 \- Internal Control ProcessorIf the WCM had been replaced prior to this software update, the original keys/FOBIKs will need to be replaced.
