Checking Passenger Side Temperature Damper Motor Function

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.

HINT: Diagnostic trouble codes (DTCs) ECC-212, ECC-221, ECC-232 and ECC-236 stored at the same time indicate a fault in a common section of the damper motors circuit. The status of the fault can be read off by checking the diagnostic trouble code (DTC) counter. This is why this fault-tracing should be carried out.
