Reading Off And Programming Data
With this option it is possible to read programmed data and to program in data.
Note. If the control module has been replaced, the position of the windows must be initiated using a diagnostic function. A window must be in its uppermost position before it can be initiated.
No customer related programming is available in the control module.
The control module has a built-in diagnostic system, Volvo Diagnostic, which continuously monitors internal functions as well as input and output signals.
This function can be used to continuously read off the values and status of the control module's input and output signals.
The key must not be in the ignition when reading off the status of the door mirror lamp.
Lock cable M1, status, is active while locking the central locking
Lock cable M2, status, is active while unlocking the central locking and / or deadlocks
Lock cable M3, status, is active while locking the deadlocks
The following parameters can be read off
- The status of the front left window up-control
- The status of the front left window down-control
- The status of the front left window auto-control
- The status of the front right window up-control
- The status of the front right window down-control
- The status of the front right window auto-control
- The status of the rear left window up-control
- The status of the rear left window down-control
- The status of the rear right window up-control
- The status of the rear right window down-control
- The status of the child safety button NOTE: A diagnostic trouble code (DTC) is stored if the child safety button is activated for 10 seconds.
- The status of the selection of control for the left door mirror
- The status of the selection of control for the right door mirror
- The status of the upward control for the door mirror
- The status of the downward control for the door mirror
- The status of the control for the left door mirror
- The status of the control for the right door mirror
- The status of the up-motor for the power window
- The status of the down-motor for the power window
- Lock cable M1, status
- Lock cable M2, status
- Lock cable M3, status
- The status of the door open warning lamp (does not apply to all cars)
- Defroster, status
- Door mirror lamp, status
- Outside temperature, value NOTE: The outside temperature can only be read off from the control module on the right-hand side of the car.
- Power supply, value
- Signal supply, value
- Door mirror position X axis, value (does not apply to all cars)
- Door mirror position Y axis, value (does not apply to all cars).
Use this option to activate components / functions in the driver's door module.
The following components / parameters can be activated in alternative ways
- The up / down control for the front left window
- The up / down control for the front right window
- The up / down control for the rear windows
- The selection of the left or right door mirror control
- Upwards / downwards / left / right door mirror control
- Power window motor, up / down
- Lock cable M1
- Lock cable M2
- Door mirror motor
- Defroster
- Door mirror lamp
- Door open warning lamp (does not apply to all cars).
With this option it is possible to read programmed data and to program in data.
Note. If the control module has been replaced, the position of the windows must be initiated using a diagnostic function. A window must be in its uppermost position before it can be initiated.
No customer related programming is available in the control module.
New software can be downloaded into the driver door module (DDM) and passenger door module (PDM). When ordering software, the hardware and the software in the car is compared to the data in 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 is not OK, the database is updated with the car configuration. When this is complete the software is downloaded.
The window positions must be re-initialized after the driver door module (DDM) or passenger door module (PDM) is replaced. This is so that the new control module stores the closed position of the window. Initialization is carried out using VIDA.
If the car has power seats with memory for the door mirrors, this function can be switched off. This means that the personal settings for the door mirrors, based on the remote control used to unlock the door, can be deactivated. Deactivation is carried out using VIDA. This function can be switched off on cars from model year 2003. This setting will be stored in the control module after deactivation, but not in the Volvo Central Database. This means that the deactivation must be repeated when hardware is replaced.
Scheme 2101
Window control is activated via switches on the driver door module (DDM) (3/126) and passenger door module (PDM) (3/127). The motor for the power window on the driver's side (6/58) is controlled directly from the driver door module (DDM). The motor for the power window on the passenger side (6/60) is controlled via CAN communication from the driver door module (DDM) to the passenger door module (PDM). The signals for operating the rear windows are transmitted from the driver door module (DDM) via the controller area network (CAN) to the central electronic module (CEM) (4/56), which manages the rear window functions.
More detailed information about the rear windows and child locking can be found in Design and Function, central electronic module (CEM).
The passenger door module (PDM) only operates the front window on the passenger side. The signal for operating the front passenger window is transmitted from the passenger door module (PDM) to the window lift mechanism motor on the passenger side (6/60).
If the child lock is activated from the driver door module (DDM), the rear windows cannot be operated from the rear seat. When the child lock switch is activated, a signal is transmitted from the driver door module (DDM) on the controller area network (CAN) to the central electronic module (CEM) which disables rear window operation.
