Points To Observe When Replacing The Control Module

Software can only be ordered when the control module is installed in the vehicle. VIDA (Volvo scan tool) reads off the new control module identity which is required to order the correct software.

Wait two 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 runs on after the ignition has been switched off, wait until it stops. Then wait another two 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.
