Points to observe when replacing the control module

WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION:

: New software can only be ordered when the control module is installed in the car. VIDA reads off the new control module identity, which is required to order the correct software.

CAUTION:

Wait two minutes after the ignition has been turned off. The main relay must be voltage free before  the control module can be removed from the car. If the electric cooling fan runs on after the ignition has been turned off, wait until it stops. Then wait an additional two minutes.

CAUTION:

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.
