Position Display, Function (Up To 4/24/04)

The position display and program selection display in the instrument cluster (A1) is actuated via the CAN engine compartment. The program selection performed at the transmission mode switch (S16/5) is transmitted from the ETC [ETC] control unit (N15/3) to the instrument cluster (<>) and the selector lever position is transmitted from the electronic selector lever module control unit (N15/5) to the instrument cluster (A1). See Fig 1.

The program selection performed at the transmission mode switch (S16/5) remains stored only after driving approximately 1 minute and is then displayed again after the engine is started again. The driving time required of approximately 1 minute is due to the system.

The shift pattern display (87) is illuminated when the driving lights are switched on.
