• Ignition on.

  The diagnostic trouble code (DTC) is stored because the engine control module (ECM) registered discrepancies in components or functions. The engine control module (ECM) was forced to reconfigure the system using substitute values, negatively affecting the driveability of the car. It is probable that diagnostic trouble codes (DTCs) for faulty components and/or functions are also stored in the engine control module (ECM). These diagnostic trouble codes (DTCs) must be fault-traced and any faults remedied first.

  Check whether other diagnostic trouble codes (DTCs) are stored in the engine control module (ECM).

  • Ignition on
  • Click on the VCT2000 symbol to read off the diagnostic trouble codes (DTCs).
