WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.
Points to observe when replacing the control module:
- If moving a control module from one car to another, remember to note any diagnostic trouble code (DTC) (s) and operating times before removing the control module from the car
- Always check that the terminals or pins in the control module connectors are not bent or damaged. This may have been the cause of the fault.
Cut off the tie strap holding the cable section to the control module.
Remove the control module. Remove the 2 nuts.
HINT: Slacken off the uppermost nut. Leave it in place, screwed in a few turns.
Pull the control module from the mounting.
Position a screwdriver between the control module connector and its locking handle as shown. Turn the screwdriver to release the catch.
Continue pulling the locking handle outwards until the connector comes away from the control module.
