ENGINE IMMOBILISER SYSTEM (w/o Entry and Start System) - Engine does not Start because No Initial Combustion


DESCRIPTION

  1. When a key is inserted into the ignition key cylinder, the transponder key coil receives the key ID code and sends it to the transponder key ECU assembly.
  2. If an error in communication between the transponder key coil and transponder key ECU assembly occurs, this symptom may occur.
