17978/P1570/005488 - Engine Start Blocked by Immobilizer

Possible Symptoms

  • Engine starting but stalling immediately

Possible Causes

  • Key(s) not matched
  • Instrument Cluster not matched
  • Engine Control Unit (ECU) not matched
  • Engine Control Unit (ECU) Power Supply faulty

Possible Solutions

  • Check Immobilizer Measuring Values (usually in Instrument Cluster OR Immobilizer Control Module)
  • Match Key(s)/Instrument Cluster/Engine Control Unit (ECU)
  • Check Engine Control Unit (ECU) Power Supply (Relay)

Special Notes

  • If no other immobilizer related fault codes are stored and the immobilizer related meas. blocks are fine except Engine Start not allowed, in rare occasions it helps to try cold-booting the car. Remove both battery cables from the battery. Short the battery cables together (away from the battery) for about 15 seconds. Reconnect the battery. (Example)
