Points to observe when replacing the control module
CAUTION: The software can only be ordered when the control module is installed in the car. VADIS reads off the new control module identity. This is
required so that the correct software can be ordered.
The software can only be ordered when the control module is installed in the car.
CAUTION:
-
Wait 2 minutes after the ignition has been switched off. The main relay must be voltage free before the control module can be removed from the
car. If the engine cooling fan (FC) runs on after the ignition has been switched off, wait until it stops and then wait for a further 2 minutes.
-
Always check that the control module and control module box connector pins and sleeves are not bent or damaged. This may have caused the
fault.
