Common Data, ECC-211, ECC-212, ECC-231 and ECC-232: Information: Overview
The following diagnostic trouble codes (DTCs) can be detected and stored for the position sensors for the temperature damper motors:
- ECC-211 Driver's side temperature damper motor position sensor
- ECC-212 Driver's side temperature damper motor position sensor
- ECC-231 Passenger side temperature damper motor position sensor
- ECC-232 Passenger side temperature damper motor position sensor.
The climate control module incorrectly detects the signal from the temperature damper motor position sensor. Control of the temperature motors is stopped. The temperature in the passenger compartment cannot be adjusted. The orange LEDs on the control panel flash. The above diagnostic trouble codes (DTCs) 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.
Updating settings
- Model year 1997-1998
Use the Volvo Scan Tool (ST) with an updated memory cassette as a stand-alone tool. Updating is automatic when diagnostic trouble codes (DTCs) are read off. Alternatively, select updating from the menu to update manually
- Model year 1999-
Use VIDA. Select VIDA vehicle communication. Updating is automatic when diagnostic trouble codes (DTCs) are read off. Alternatively, select the specific data from the menu to update manually.
HINT: VIDA vehicle communication with model year 1999- selected also functions for model years 1997 and 1998 for this update.
Select "Continue" to check the function of the climate control system.
