Removing PCM display and control unit

Removing display for the PCM operator control unit
Switch off ignition and remove ignition key.







1. Loosen the side fastening screw a few turns.







2. Insert a hexagon-socket wrench sideways into the screw connection of the PCM detent hooks.
3. Close the detents (2 each side) with an Allen key -A- and carefully pull out the PCM.
4. For reinstallation, open the detents with the hexagon-socket wrench -B-.

The number of plug connections will vary, depending on the I No. (CD changer, amplifier, etc.).

The variant without additional audio components (external Most control units) has a jumper (output to input) connected to the optical waveguide plug.







5. Unlock antenna plug -D, E- and remove.
6. Unlock and disconnect the electrical plug connections in the order -A, B, C-.

Installing display and PCM operator control unit







1. Push on the electrical plug connections for the display and operator control unit in the sequence -C, B, A- and the antenna amplifiers -D, E- until the plugs are felt to engage.







2. Check that the locking tabs on the PCM are out, open the lock with an Allen key if necessary.

INFORMATION:
- Before sliding the PCM/radio into the installation slot, make sure that the electric lines are not trapped by the PCM/radio or damaged.
- After installation of a new display and PCM/radio operator control unit, the system must be activated with the PIWIS tester 9718.

3. Push the navigation unit into the installation slot until the locks engage on the PCM housing.







4. Screw in the locking screw for the PCM and tighten it.

Reading out PCM display and control unit

Reading from and writing to the PCM display and operator control unit

INFORMATION:
- When installing a new PCM/CDR in a vehicle, the PCM/CDR code specified in the PIWIS Infosystem should be available. Normally, the code is stored in the instrument cluster and is read out from the PCM/CDR.
- You can get the codes from the PIWIS Infosystem or from your importer by specifying the vehicle identification number.
- During coding, there should be a guaranteed power supply for the PIWIS Tester 9718. A battery charger with a current rating of at least 40 A must be connected to the vehicle battery.
- The PIWIS Tester 9718 instructions take precedence and in the event of a discrepancy these are the instructions that must be followed. Deviations may occur with later software versions.
- The procedure described here has been structured in general terms; different text or additions may appear in the PIWIS Tester 9718.

1. PIWIS Tester 9718 must be connected to the vehicle. Start the PIWIS Tester. Switch on ignition and press >>.

10. Select Equipment and press >>.

The following codings can be performed:

INFORMATION:
- When installing a new PCM/CDR in a vehicle, the PCM/CDR code specified in the PIWIS information system should be available. Normally, the code is stored in the instrument cluster and is read out from the PCM/CDR.
- You can get the codes from the PIWIS info system or from your importer by specifying the vehicle identification number.
- During coding, it is essential to guarantee the power supply for the PIWIS Tester 9718. A battery charger with a current rating of at least 40 A must be connected to the vehicle battery.
- The PIWIS Tester 9718 instructions take precedence and in the event of a discrepancy these are the instructions that must be followed. Deviations may occur with later software versions.
- The procedure described here has been structured in general terms; different text may appear in the PIWIS Tester 9718 or additional information/steps may be displayed or required.

41. If the PCM/vehicle equipment does not have a DVD navigation unit, then adjust the time/date using the SET button on the PCM and in the menu PCM system.
42. For vehicle equipment with DVD navigation unit, switch on the PCM in clear surroundings (to load GPS almanac); as soon as four satellites are identified the almanac will reload. The time is updated again when there is a plausible GPS reception (four satellites). The date and time are also adopted once the GPS almanac has been loaded; it may be necessary to change over to summer time (daylight-saving time). This time is transferred to the instrument cluster. If the time is then manually changed by means of the instrument cluster, this time is adopted by the PCM and synchronised with GPS time.
43. For vehicle equipment with telephone, the telephone is enabled again when the telephone PIN code is entered with the SIM telephone card inserted.
