Self-Adjustment Of Damper Motors
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.
The climate unit damper motors can be self-adjusted with this service. The damper motors are self-adjusting after any of them has been removed or replaced or other work is carried out on the damper or linkage. To ensure correct self-adjustment the damper motors must have voltage at generator supply level, e.g. the engine must be idling.
To activate self-adjustment, proceed as follows:
- start engine
- wait approximately 3 seconds
- start engine without switching off the ignition before
- wait 0.5 seconds after releasing the key to position II. If diagnostic trouble code (DTC) is stored the indicator LED will flash once. Only start pressing the buttons after the flashing
- press in the REC button three times within the following 2.5 seconds.
NOTE:
The control module will automatically adjust the damper motors when it is connected to the car's 30 supply on condition that the control module has been disconnected for more than 2 minutes. Engine idling during self-adjustment.
