Diagnostic Trouble Code (DTC) Information

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.

Condition

Fig 1: Identifying Climate Unit Damper Motor

The climate control module incorrectly detects the signal from the temperature damper motor position sensor. The control of the temperature motors stops, the temperature in the passenger compartment cannot be adjusted, the orange LEDs on the control panel flash and the diagnostic trouble codes (DTCs) ECC-211,ECC-212, ECC-231 and ECC-232 may be stored. The diagnostic trouble codes (DTCs) for the position sensors are therefore stored unnecessarily without there actually being a fault. This, in turn, causes an abnormally large number of fault free damper motors to be replaced. Settings in the climate control module for these diagnostic trouble codes (DTCs) must be updated.

Any updating that is carried out means that the above diagnostic trouble codes (DTCs) are not detected and stored.

Substitute Value

None.

Possible Source

Faulty detecting of the position sensor signal.

Fault symptom[s]

The orange LED flashes.
