Displays Test
Certain instrument panel cluster (IPC) features are tested when the ignition is turned on in order to verify the features are working properly. The following occurs at key up:
| • | The air bag indicator flashes 7 times (not IPC controlled). |
| • | The ABS indicator illuminates briefly. |
| • | The battery indicator illuminates briefly. |
| • | The brake indicator illuminates briefly. |
| • | The coolant temperature indicator |
| • | The engine oil pressure indicator illuminates briefly. |
| • | The malfunction indicator lamp (MIL) illuminates briefly (not IPC controlled). |
| • | The seat belt indicator illuminates for 70 seconds or until the driver seat belt is latched (not IPC controlled). |
| • | The security indicator illuminates briefly. |
| • | The tire pressure low indicator |
| • | The vehicle dynamics caution (VDC) indicator |
| • | All message center segments illuminate briefly. |
Indicators and Warning Messages
Refer to
Indicator/Warning Message Description and Operation.
Engine Coolant Temperature Gage
The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the engine control module (ECM) or the powertrain control module (PCM). The IPC receives a serial data message from the ECM/PCM indicating the engine coolant temperature.
The engine coolant temperature gage defaults to "°C" or below if:
| • | The ECM/PCM detects a malfunction in the engine coolant temperature sensor circuit. |
| • | The IPC detects a loss of serial data communications with the ECM/PCM. |
| • | The body control module (BCM) detects a loss of serial data communications with the ECM/PCM. |
| • | The IPC detects a loss of serial data communications with the BCM. |
Fuel Gage
The instrument panel cluster (IPC) displays the fuel level as determined by the engine control module (ECM)/powertrain control module (PCM). The IPC receives a serial data message from the ECM/PCM indicating the fuel level percent. The fuel gage defaults
to empty if:
| • | The ECM/PCM detects a malfunction in the fuel level sensor circuit. |
| • | The IPC detects a loss of serial data communications with the ECM/PCM. |
| • | The IPC detects a loss of serial data communications with the body control module (BCM). |
When the fuel level is less than a pre-determined value, the low fuel message is displayed in the DIC.
Odometer
The vehicle odometer is calculated and stored electronically in the instrument panel cluster (IPC). The IPC contains a season odometer and trip odometer A or B in the trip/fuel switch menu. Momentarily press the trip/fuel switch in order to cycle through
the trip/fuel menu. Press the set/reset switch momentarily, while a trip odometer is displayed, in order to reset the trip odometer. Pressing the set/reset switch for 2 seconds will reset a trip odometer. The vehicle mileage and trip mileage is displayed
as determined by the IPC. The IPC calculates the mileage based on the serial data vehicle speed information from the ECM/PCM. The IPC receives the vehicle odometer information from the body control module (BCM) via the serial data circuit. The odometer will
display 'error' if an internal IPC memory failure is detected. The odometer displays either miles or kilometers as requested through the DIC Vehicle Information Menu.
PRNDL Display
The instrument panel cluster (IPC) displays the selected gear position as determined by the engine control module (ECM)/powertrain control module (PCM). The IPC receives a serial data message from the ECM/PCM indicating the gear position. The PRNDL displays
blank if:
| • | The ECM/PCM detects a malfunction in the transmission range switch circuit. |
| • | The IPC detects a loss of serial data communication with the ECM/PCM. |
| • | The IPC detects a loss of serial data communication with the body control module (BCM). |
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed as determined by the engine control module (ECM)/powertrain control module (PCM). The IPC receives vehicle speed information from the body control module (BCM) via serial data messages. The
speedometer defaults to 0 km/h (0 mph) when the IPC detects a loss of serial data communication with the ECM/PCM or the BCM.
Tachometer
The instrument panel cluster (IPC) displays the engine speed as determined by the engine control module (ECM)/powertrain control module (PCM). The IPC receives a serial data message from the engine control module (ECM)/powertrain control module (PCM) indicating
the engine speed. The IPC receives engine speed information from the body control module (BCM) via serial data messages. The tachometer will default to 0 RPM if:
| • | The ECM/PCM detects a malfunction in the engine speed signal circuit. |
| • | The IPC detects a loss of serial data communication with the ECM/PCM. |
| • | The IPC detects a loss of serial data communication with the BCM. |
