Certain instrument cluster features are tested when the ignition is turned on in order to verify the features are working properly. The following occurs when the ignition is turned on:
| • | The ABS indicator illuminates briefly. |
| • | The battery indicator illuminates briefly. |
| • | The brake indicator illuminates briefly. |
| • | The door ajar indicator illuminates briefly. |
| • | The fuel level low indicator illuminates briefly. |
| • | The oil pressure low indicator illuminates briefly. |
Refer to Indicator/Warning Message Description and Operation .
The trip odometer can be accessed through the top of the instrument cluster driver information centre switch Up/Down function.
This message indicates the estimated distance that the vehicle can travel under the current fuel economy and fuel level conditions since the last battery connection to the instrument cluster.
Fuel Range is calculated using the equation:
Fuel Range = Range
Distance/Range Fuel Used.
| • | Range Distance = The accumulated distance travelled since the last reset of this value |
| • | Fuel Used = The accumulated fuel delivered since the last reset of this value |
The engine control module (ECM) sends the fuel range value to the instrument cluster. The instrument cluster receives a serial data message with fuel information.
The fuel range value is retained during ignition OFF. The Fuel Range display cannot be reset. LOW is displayed when fuel range is below a predetermined value.
Average speed is calculated using the equation:
Average Speed = Average Speed Distance/Average Speed Time.
| • | Distance = The accumulated distance travelled since the last reset of this value |
| • | Ignition ON = The accumulated ignition on time since the last reset of this value |
The instrument cluster displays the fuel level based on the information from the ECM. The ECM converts the data from the fuel level sensors to a fuel level signal. The ECM sends the fuel level signal via a Low Speed CAN-Bus signal to the instrument cluster. If the fuel level falls under 11% the instrument cluster switches on the low fuel level indicator. The fuel gauge defaults to empty if:
| • | The ECM detects a malfunction in the fuel level sensor circuit. |
| • | The instrument cluster detects a loss of serial data communications with the ECM. |
The instrument cluster displays the vehicle speed based on the information from the ECM. The ECM sends the vehicle speed information via a Low Speed CAN-Bus signal to the instrument cluster.
The speedometer defaults to 0 km/h (0 MPH) if:
The instrument cluster detects a loss of serial data communications with the ECM.
The instrument cluster displays the engine speed based on the information from the ECM. The ECM converts the data from the engine speed sensor to an engine revolution signal. The ECM sends the engine speed information via a Low Speed CAN-Bus signal to the instrument cluster.
The tachometer defaults to 0 RPM if:
| • | The ECM detects a malfunction in the engine speed sensor circuit. |
| • | The instrument cluster detects a loss of serial data communications with the ECM. |
Note: Actual RPM from the engine, RPM from the data display of scan tool and RPM from the instrument cluster are not equal. Refer to the following chart if the RPM information is needed for the diagnosis.
Actual RPM | 600 | 700 | 800 | 900 | 1000 | 1100 | 1200 | 1300 | 1400 |
Scan tool RPM | 600 | 600 | 600 | 600 | 800 | 1000 | 1000 | 1200 | 1200 |
Cluster RPM Segment(s) | 3 | 3 | 3 | 3 | 4 | 5 | 5 | 6 | 6 |
Actual RPM | 1500 | 1600 | 1700 | 1800 | 1900 | 2000 | 2100 | 2200 | 2300 |
Scan tool RPM | 1400 | 1600 | 1600 | 1800 | 1800 | 2000 | 2000 | 2200 | 2200 |
Cluster RPM Segment(s) | 7 | 8 | 8 | 9 | 9 | 10 | 10 | 11 | 11 |
