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.
Removing the control module
-
Ignition off. Wait for 2 minutes
-
Remove the cover over the control module box. Put the cover to one side.
NOTE: Do not touch the control module terminal pins with your fingers. Static electricity may damage components in the control module.
