Power Seat Control Module: Programming and Relearning
Downloading Software And Replacing The Control Module
New software can be downloaded into the power seat module.
When ordering software, the hardware and the software in the car is compared to the Volvo central database. If the comparison is OK the software is
downloaded to the control module.
If the comparison between the car and Volvo central database does not correspond, the database is updated with the configuration of the car. New
software is downloaded after the update is complete.
A control module may already have software installed which will result in incorrect information being updated on Volvo's Central Database. To avoid
this, tick the box in the VIDA software manager indicating the software has been replaced when the control module has been replaced.
A number of customer parameters can be programmed into the power seat module. These customer parameters are stored in the control module but not in
the Volvo central database. This means that the customer parameters must be reprogrammed when the hardware is replaced and when downloading
software.
The power seat module calculates the current required by the motors. A current limit can be set to protect the wiring from high currents.
-
There is a parameter which detects when the seat has reached its limit position, in other words blocked motor. (Programmable)
-
There is a parameter for detecting short-circuits (Can be read off).
The value of the current for a blocked motor can be set using the diagnostic tool. When programming, the value of the blocked motor must be less than
the value for a short-circuit. If this is not the case, the control module will indicate a short-circuit in the cable when the seat is run to its limit position.
The motor stops when the current exceeds the value for a blocked motor and the control module registers no pulses from the Hall sensor. The level of
current for a blocked motor can be set between 9 and 20 Amperes.
It is possible to reprogram the function so that the seat is automatically set by remote control. With this function activated the seat can be set using the
remote control. This function is removed if it is deactivated.
