Instrument Cluster
The virtual display Instrument Cluster (IC) is connected to the Body Control Module/Gateway Module (BCM/GWM) on the High Speed (HS) Controller Area Network (CAN) comfort systems bus. The Transmission Control module (TCM) is connected to the BCM/GWM on the FlexRay systems bus.
Automatic transmission status is transmitted from the TCM to the virtual display IC via the BCM/GWM. Transmission status is indicated to the driver by a message in the message center or illumination of a warning indicator.
For additional information, refer to: INSTRUMENT CLUSTER .
The Thin Film Transistor (TFT) display instrument cluster is connected to the TCM via the HS CAN powertrain systems, the BCM/GWM and the FlexRay systems bus. Transmission status is transmitted by the TCM and displayed to the driver in one of two displays in the instrument cluster.
For additional information, refer to: INSTRUMENT CLUSTER .
Malfunction Indicator Lamp
The Malfunction Indicator Lamp (MIL) is located in the virtual display Instrument Cluster (IC). Transmission related faults which may affect the vehicle emissions will illuminate the MIL.
The MIL is illuminated by the Powertrain Control Module (PCM) on receipt of a relevant fault message from the Transmission Control Module (TCM) on the FlexRay system bus. The nature of the fault can be diagnosed using approved diagnostic equipment which reads the fault codes stored in the TCM memory.
Transmission Status Display
The transmission status display is located in the virtual display Instrument Cluster. The display shows the Transmission Control Switch (TCS) or the selected gear when in manual and sport modes.
The following table shows the displays and their descriptions.
| SYMBOL | DESCRIPTION |
|---|---|
| P | Park selected |
| R | Reverse selected |
| N | Neutral selected |
| D* | Drive and temporary manual mode selected (* = current gear) |
| S* | Sport mode selected (* = current gear) |
| 1 | 1st gear selected (manual CommandShift mode) |
| 2 | 2nd gear selected (manual CommandShift mode) |
| 3 | 3rd gear selected (manual CommandShift mode) |
| 4 | 4th gear selected (manual CommandShift mode) |
| 5 | 5th gear selected (manual CommandShift mode) |
| 6 | 6th gear selected (manual CommandShift mode) |
| 7 | 7th gear selected (manual CommandShift mode) |
| 8 | 8th gear selected (manual CommandShift mode) |
Message Center
The message center is located in the virtual display Instrument Cluster (IC). The message center display relays vehicle status and operating information to the driver and can display messages relating to a number of vehicle systems. If a transmission fault occurs, the message GEARBOX FAULT is displayed in the message center. For additional information, refer to: INSTRUMENT CLUSTER .
