ABS Indicator
The ABS indicator illuminates in the IPC when the following occurs:
| • | The electronic brake control module (EBCM) detects a malfunction in the ABS system. |
| • | The displays test is performed in the IPC at the start of each ignition cycle. |
Brake System Indicator
The brake indicator illuminates in the IPC when the following occurs:
| • | When the park brake is engaged and the engine is ON, the park brake switch (signal is low) activates the brake indicator. |
| • | The brake pressure differential switch detects an excessive difference in pressure between the front brakes and the rear brakes. |
| • | The EBCM detects a malfunction that will prevent it from illuminating the ABS indicator. |
| • | As a bulb check by the ignition switch when cranking the engine on vehicles equipped with daytime running lamps (DRL). |
Charging System Indicator
The charging system indicator illuminates in the IPC when the following occurs:
| • | The PCM detects that the generator output is less than 11 volts or greater than 16 volts. The PCM via the charge indicator control circuit will illuminate the indicator by grounding the charge indicator control circuit (L18). |
| • | The generator logic illuminates the indicator (L65). |
| • | The ignition is on, with the engine off. The indicator will remain on until the engine is running and the generator output will turn it off |
Check Gauges Indicator
The IPC illuminates the CHECK GAUGES indicator when the following occurs:
| • | Engine oil pressure is outside the normal operating range as received from the engine oil pressure sensor. |
| • | Engine coolant temperature is outside the normal operating range as received from the ECT sensor. |
| • | The IPC performs the displays test at the beginning of each ignition cycle. The indicator illuminates for approximately 3 seconds. |
Engine Coolant Indicator
LOW COOLANT LEVEL (DIESEL ONLY)
The low coolant level indicator module illuminates the LOW COOLANT indicator in the IPC when it detects a low coolant level from the low coolant level switch (signal is low). The low coolant level indicator module grounds the low coolant level indicator control circuit.
Fasten Safety Belt Indicator
The multifunction alarm module (MFAM) illuminates the fasten safety belt indicator when the following occurs:
| • | The ignition is in RUN and the driver seat belt is not buckled (switch signal is low). The MFAM also monitors the driver seat belt switch signal and activates an audible alarm for approximately 8 seconds as a reminder to buckle the seat belt. |
| • | As a bulb check by the MFAM at the beginning of each ignition cycle. The indicator illuminates for approximately 3 seconds. |
Fuel System Indicator
WATER IN FUEL (DIESEL ONLY)
The WATER IN FUEL indicator illuminates in the IPC when the following occurs:
| • | The water in fuel sensor (primary or secondary) detects water in the fuel tank. The sensor grounds the water in fuel indicator control circuit. |
| • | As a bulb check by the ignition switch at the beginning of each ignition cycle. The indicator illuminates for approximately 3 seconds. |
Lighting System Indicators
DAYTIME RUNNING LAMPS (DRL)
The DRL module illuminates the DRL indicator when the ignition is in RUN, the headlamp switch is in OFF and the park brake is released. The IPC provides battery positive voltage and the DRL module illuminates the indicator by grounding the DRL indicator control circuit. Any function that turns on the headlamps, will terminate the DRL operation.
HIGH BEAM
The headlamp dimmer switch activates the high beam indicator in the IPC when high beam is requested. The headlamp dimmer switch provides battery positive voltage directly to the high beam indicator control circuit. The IPC provides ground for the high beam indicator control circuit.
TURN SIGNALS
The turn signal indicator illuminates in the IPC when a turn signal or hazard is requested from the switch. The turn signal switch provides battery positive voltage to the indicator when the turn signal or hazard is requested. The IPC provides ground for the turn signal indicator control circuit.
Malfunction Indicator Lamp (MIL)
The PCM illuminates the MIL (service engine soon or check engine) when the following occurs:
| • | The PCM detects a malfunction in the emissions system. |
| • | The PCM performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds. |
| • | The ignition is on, with the engine off. |
Reduced Engine Power Indicator (Gas Only)
The PCM illuminates the reduced engine power indicator in the IPC when the PCM detects a malfunction in the throttle actuator control (TAC) system. The PCM grounds the reduced engine power indicator control circuit.
Theft System Indicator
SECURITY
The vehicle theft deterrent module illuminates the SECURITY indicator in the IPC. The vehicle theft deterrent module via the security indicator control circuit illuminates the indicator by grounding. The module monitors and relies on the passlock sensor signal to illuminate the indicator. The VTD system uses the indicator as a malfunction indicator. If the security indicator flashes or stays ON continuously during vehicle operation, refer to the system diagnosis.
Throttle System Indicator
SERVICE THROTTLE SOON (Diesel Only)
The PCM illuminates the SERVICE THROTTLE SOON indicator in the IPC when the PCM detects a malfunction in the throttle system. The PCM grounds the service throttle soon indicator control.
Wait To Start Indicator (Diesel Only)
The WAIT TO START indicator illuminates in the IPC as determined by the PCM. With the ignition ON and the engine OFF the PCM monitors the glow plugs and during the pre glow condition illuminates the indicator by grounding the wait to start indicator control circuit. The PCM will turn the indicator OFF when the glow plugs reach normal operating condition and the vehicle is ready to start.
