Status Indication
Instrument Cluster
| Item Number | Description |
|---|---|
| A | High-line instrument cluster |
| B | Low-line instrument cluster |
| 1 | Low-range status indicator |
| 2 | Message centre text (high-line only) |
| 3 | Driveline fault lamp |
| 4 | Driveline over temperature |
On vehicles fitted with the high line instrument cluster there will be one low range status indicator. This indicator will take the form of a mountain symbol and has the following logic:
- Lamp on = low range
- Lamp off = high range
- Lamp flashing = range change in progress/range undefined/range fault.
There will also be a message displayed in the message centre, on vehicles with high-line instrument cluster, which will inform the driver of any faults with the transfer box.
The following table shows the messages that can be displayed in the message centre of a high-line instrument cluster relating to the transfer box:
| Message | Description | Chime |
|---|---|---|
| 'LOW RANGE ENGAGED' | Transfer case has engaged low range after a range change request | Single |
| 'HIGH RANGE ENGAGED' | Transfer case has engaged high range after a range change request | Single |
| 'SPEED TOO HIGH FOR RANGE CHANGE' | Range change request when vehicle speed too high | Single |
| 'SELECT NEUTRAL FOR RANGE CHANGE' | Range change request when lever not in neutral | Single |
| 'APPLY HANDBRAKE' (PARK BRAKE in USA and Canada) | This alerts the driver that the automatic transmission park lock function is inoperative due to transfer box out of high or low range. Transfer box control module has stopped transmitting on the CAN bus during a range change or while in neutral mode and as a result the automatic transmission park lock function is inoperative |
One per second for three seconds |
| 'TRANSMISSION RANGE CHANGE NOT AVAILABLE' | Transfer box has detected a fault inhibiting a new range change. Control unit has shut down due to thermal overload | Single |
| 'CENTRE DIFF OVER TEMP REDUCE SPEED' | Centre differential temperature is approaching the over heated threshold | Single |
| 'CENTRE DIFF FAULT - TRACTION REDUCED' | Centre differential has failed - operating as an open differential | Single |
| 'CENTRE DIFF FAULT - TRACTION REDUCED' | Transfer box control module has stopped transmitting on the CAN bus and defaults to open centre differential | Single |
The transfer box control module receives a gear position signal from the manual transmission gear position sensor and publishes the status on the CAN bus. This is displayed in the odometer display, similar to how the automatic transmission displays gear information.
| Odometer Display | Description |
|---|---|
| N | Transmission is in neutral |
| 1 | Transmission is in first gear |
| 2 | Transmission is in second gear |
| 3 | Transmission is in third gear |
| 4 | Transmission is in forth gear |
| 5 | Transmission is in fifth gear |
| 6 | Transmission is in sixth gear |
| R | Transmission is in reverse gear (Japan only) |
| Blank display | Transmission is between neutral and a gear |
| E | Transmission gear position sensor has a fault |
On vehicles fitted with the low line instrument cluster, in place of the message centre there will be a status lamp, which has the following logic:
- Amber - Over temperature
- Red - Failure, stop vehicle
The following table shows the faults that could possibly illuminate the transfer box status lamp on vehicles fitted with the low-line instrument cluster:
| Indication | Description |
|---|---|
| OFF | Transfer box is operating at normal working temperature |
| YELLOW WARNING LAMP ON | Transfer box temperature is approaching the over heated threshold |
| YELLOW WARNING LAMP ON | Transfer box has detected a fault, which affects the range change function (current range is still maintained) or the centre differential has failed to open. |
| RED WARNING LAMP ON | Transfer box has detected a fault which renders the transmission park lock function inoperative due to out of range condition, OR centre differential has failed with a non-zero locking torque |
| YELLOW WARNING LAMP ON | Transfer box control module has stopped transmitting on the CAN bus and defaults to open centre differential |
| RED WARNING LAMP ON | Transfer box control module has stopped transmitting on the CAN bus during a range change or while in neutral mode and as a result the automatic transmission park lock function is inoperative |
