Note: When the ignition is switched on, all control lamps of the on-board control system display unit should light up for 5-7 s. If this does not happen, then the display unit or its power circuit is faulty (see "Fuse and relay mounting block", fuse F10).
Removing
1. Remove the instrument panel trim without disconnecting the wiring harness blocks from it (see "Dashboard - removal and installation").
2. Disconnect the wiring harness block from the display unit.
3. Using a Phillips screwdriver, unscrew the two screws securing the block to the overlay.
4. Remove the display unit.
Installation
We install the display unit of the onboard control system in the reverse order.
