MODEL YEAR:

SUBJECT:
Immobilizer Warning Lamp Lit or Flashing, IMMO-DTC 321
REFERENCE:
VIDA
DESCRIPTION:
In S40 and V40 cars, the Immobilizer warning lamp may be lit after a successful cold start.
After a restart, or after switching ignition off and on, the warning lamp is not lit any more.
While the warning lamp is lit (engine is still running), Immobilizer Diagnostic Trouble Code IMMO-DTC 321 is stored. This DTC indicates a communication problem between IMMO-ECU and ECM (Engine Control Module). When the warning lamp is not lit, there are no IMMO or ECM DTCs stored.
The customer may also experience intermittent no crank (starter motor not activated) and flashing Immobilizer warning lamp in the DIM. In most cases the engine will crank normally if the ignition is switched off and a new start attempt is made. In a few cases, several start attempts are needed to get the engine running.
