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 illuminates briefly. |
| • | Cruise Engaged Indicator illuminates briefly. |
| • | 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 illuminates briefly. |
| • | The vehicle dynamics caution (VDC) indicator illuminates briefly. |
| • | All message center segments illuminate briefly. |
| • | All odometer segments illuminate briefly. |
| • | The PRND321 segment illuminates 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). The IPC receives a serial data message from the ECM indicating the engine coolant temperature. The engine coolant temperature gage
defaults to 60°C (140°F) or below if:
| • | The ECM detects a malfunction in the engine coolant temperature sensor circuit. |
| • | The IPC detects a loss of serial data communications with the ECM. |
Fuel Gage
The instrument panel cluster (IPC) displays the fuel level as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the fuel level percent. The fuel gage defaults to empty if:
| • | The ECM detects a malfunction in the fuel level sensor circuit. |
| • | The IPC detects a loss of serial data communications with the ECM. |
When the fuel level is less than a pre-determined value, the low fuel message displays 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. Momentarily press the trip/reset switch on the IPC in order to toggle between the season odometer
and the trip odometer. Press the trip/reset switch for greater than 2 seconds, while the trip odometer is displayed, in order to reset the trip odometer. The IPC displays the vehicle mileage and trip mileage as determined by the IPC. The IPC calculates
the mileage based on the serial data vehicle speed information from the engine control module (ECM). The odometer will display 'error' if an internal IPC memory failure is detected. The odometer displays either miles or kilometers as requested by the activation
of the English/metric button on the IPC.
PRND321 Display
The instrument panel cluster (IPC) displays the selected gear position as determined by the transmission control module (TCM). The IPC receives a serial data message from the TCM indicating the gear position. The PRND321 display blanks if:
| • | The TCM detects a malfunction in the transmission range switch circuit. |
| • | The IPC detects a loss of serial data communications with the TCM. |
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed as determined by the engine control module (ECM). The IPC calculates the mileage based on vehicle speed serial data message from the ECM. The speedometer defaults to 0 km/h (0 mph)
if the IPC detects a loss of serial data communications with the ECM.
Tachometer
The instrument panel cluster (IPC) displays the engine speed as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine speed. The tachometer will default to 0 rpm if:
| • | The ECM detects a malfunction in the engine speed sensor circuit. |
| • | The IPC detects a loss of serial data communications with the ECM. |
