Fault finding - Replacement of components
When replacing the UCH (see MR 411, Mechanical systems, 87B, Passenger compartment connection unit).
If replacing the computer, carry out the programming and configuration operations described (see configurations
and programming).
The order of programming and configuration operations is as follows:
1 - Write the VIN, using command VP004 Write VIN.
2 - Program the UCH using command SC004 UCH programming.
3 - Configuration of the UCH (in the Configuration and programming menu) using the following commands:
CF031 Calibration,
CF019 Type of heating and air conditioning system,
CF028 Engine type,
CF171 Temperature display,
CF029 External temperature sensor,
CF173 One-touch windows/sunroof (SR)*.
CF032 See-me-home lighting,
CF021 Front fog lights,
CF014 Daytime running lights
CF193 Automatic headlight function,
CF194 Automatic wiping function,
CF035 Rain/light sensor,
CF191 Wiper intermittent speed ring,
CF024 Hazard warning lights activated by ABS,
CF108 Locking via the RAID,
CF009 Deadlocking,
CF192 Central door locking,
CF195 Type of key,
CF229 Alarm.
4 - Key allocation, using command SC015 Key allocation.
5 - Configuration of the multiplex network is used to define (in the UCH) the different computers present and which
support fault finding on the multiplex network.
