For 1990-2009 cars

### High Beam Telltale

The high beam telltale is turned ON by the cluster when requested by the BCM. This indicates to the operator of the vehicle that the high beams are ON. The indicator also comes ON when the flash-to-pass feature is used.

### Seat Belt Telltale

The seat belt telltale is turned ON by the cluster when requested by the BCM. If the driver's seat belt is not buckled, the seat belt telltale will come ON and stay ON for 7 seconds. If the driver's seat belt is not buckled after 7 seconds, the lamp will remain ON for an additional 13 seconds, followed by about 1.5 minutes of flashing. If the driver's seat belt is buckled at any time after the initial 7 second period, the lamp will be immediately turned OFF.

### Air Bag Telltale

The SDM controls the AIR BAG telltale by providing a signal to the cluster. The cluster uses the SDM signal to determine when to provide a ground for the AIR BAG telltale. The AIR BAG telltale is used in the SIR system to notify the vehicle's operator of the following:

1. Correct system operation by flashing 7 times when the ignition switch is first turned ON. The telltale will turn OFF if the system is OK.
2. To warn the operator of the vehicle of SIR electrical system malfunctions which could potentially affect the operation of the SIR system.

The AIR BAG telltale is the key to driver notification of SIR system malfunctions. For proper operation, refer to Diagnostic System Check - SIR in SIR.

The AIR BAG telltale will be turned ON for 2-3 seconds when the ignition is turned to RUN for a bulb test.

### Service (Wrench) Telltale

The SERVICE (Wrench) telltale is turned ON by the cluster when it receives a command from the PCM, BCM, or the EBTCM. The PCM or BCM will turn the SERVICE (Wrench) telltale ON for all non-emission related diagnostic trouble codes (DTCs) that require that a telltale be turned ON. Some DTCs do not turn ONa telltale but are stored to aid in diagnosis.

The SERVICE (Wrench) telltale will also be turned ON if the EBTCM has detected a fault in its own warning indicator system. If the ABS system cannot turn ON its own telltale, a message will be sent to the cluster to turn on the SERVICE (Wrench) telltale.

The SERVICE (Wrench) telltale will be turned ON for 2-3 seconds when the ignition is turned to RUN for a bulb test.

### Malfunction Indicator Lamp (MIL) (Service Engine Soon) Telltale

The MIL (SERVICE ENGINE SOON) telltale is turned ON by the cluster when it receives a command from the PCM. This indicates to the operator of the vehicle that there is a possible problem with the engine/transaxle control system.

The MIL will only be turned ON for emission related faults.

During engine start-up, the MIL (SERVICE ENGINE SOON) telltale is turned ON, for approximately 3 seconds, by the cluster for a bulb check.

The MIL will flash if a misfire is detected.

### Low Fuel Telltale

The low fuel telltale is turned ON by the cluster when it receives a command from the BCM. The cluster will turn the lamp ON when the fuel level in the tank reaches approximately 1.5 gallons.

### Coolant Temp Telltale

The coolant temp telltale is turned ON by the cluster when it receives a command from the PCM. When the engine coolant temperature or transaxle fluid is above the specified range, the coolant temp telltale will be illuminated.

### Oil Pressure Telltale

The oil pressure telltale is turned ON by the cluster when it receives a command from the PCM. This indicates to the operator of the vehicle that the oil pressure has dropped below a specified limit.

The oil pressure indicator lamp will come ON, for approximately 2-3 seconds at engine start-up, until the oil pressure raises enough to open the oil pressure switch, for a bulb check.

### Change Oil Soon Telltale

The change oil soon telltale is turned ON by the cluster when it receives a command from the PCM. The change oil soon telltale is commanded ON based on a calculated value of time and mileage. This indicates to the operator of the vehicle that the oil should be changed as soon as possible.

### Low Traction Telltale

The low traction telltale is turned ON by the cluster when it receives a command from the PCM. When the traction control system attempts to prevent wheel slip, the low traction telltale will begin to flash.

### ABS Telltale

The ABS telltale is turned ON by the cluster when it receives a command from the EBTCM.

The ABS telltale indicator lamp is turned ON, for approximately 3 seconds, during engine start-up for a bulb check.

If the telltale stays ON, it informs the driver that a problem has occurred and that the ABS system has been disabled. The vehicle should be taken in for service as soon as possible.

### Brake Telltale

The brake telltale is turned ON by the cluster when it receives a command from the BCM or the EBTCM, indicating a possible problem within the mechanical function of the brakes. This indicates to the operator of the vehicle that the park brake is engaged, brake fluid is low, or there is a possible problem in the mechanical portion of the antilock brake system.

During engine start-up, the brake indicator lamp will come ON for 3 seconds by the I/P cluster for a bulb check.

### Generator (Battery) Telltale

The generator (battery) telltale is turned ON by the cluster when it receives a command from the PCM. This indicates to the operator of the vehicle that there is a possible problem in the charging circuit.

The generator (battery) telltale indicator lamp will turn ON, for approximately 3 seconds, during engine start-up until the PCM senses voltage output by the generator for a bulb check.

### Decklid/Liftgate Ajar Telltale

The decklid/liftgate ajar telltale is turned ON by the cluster when it receives a command from the BCM. When the liftgate has been opened, the cargo lamp switch will close providing input to the BCM. This indicates to the operator of the vehicle that the decklid (sedan) or liftgate (wagon) is ajar.

### Daytime Running Lights (DRL) Telltale

The DRL ON telltale is turned ON by the cluster when it receives a command from the BCM. The telltale will be ON whenever DRL is in operation.

Important: Low resistance high beam bulbs or high charging system voltage can cause a flickering DRL telltale.

The DRL ON telltale will turn OFF if the High or Low Beams headlamps are activated or if a High Beam Headlamp fails. However, if both high beams fail, the DRL will turn ON again. This is because the DRL circuitry is unable to identify this condition.

### Security Telltale

The security telltale is turned ON by the BCM. There is a wire directly from the security telltale (LED) to the BCM. The security telltale receives battery power from circuit 2540. The security telltale is grounded through circuit 264 by the BCM.

The security telltale is related to the passlock system. For information on telltale operation, refer to Passlock System information in Theft Deterrent.

### Upshift Telltale

The upshift telltale is turned ON by the cluster when it receives a command from the PCM. The upshift telltale indicates to the operator of the vehicle when to shift to the next highest gear for maximum fuel mileage.

### Left Turn Signal Lamp

The left turn signal lamp is switched to power by the left turn signal switch. When the switch is in the left turn position, current flows though the indicator lamp which is connected to ground within the cluster. This indicates to the operator of the vehicle that the left turn signal is operating. If both the left and right turn signal indicator lamps are flashing, the hazard flashers are ON.

### Right Turn Signal Lamp

The right turn signal lamp is switched to power by the right turn signal switch. When the switch is in the right turn position, current flows though the indicator lamp which is connected to ground within the cluster. This indicates to the operator of the vehicle that the right turn signal is operating. If both the right and left turn signal indicator lamps are flashing, the hazard flashers are ON.

### Instrument Cluster Illumination Lamps

The instrument cluster has two front flood illumination lamps and four rear back-lighting lamps. The signal to control these instrument cluster illumination lamps is a pulse width modulated ground signal received from the instrument panel dimmer.

The duty cycle of the pulse width modulated (PWM) signal is varied by the vehicle's operator rotating the knob of the instrument panel dimmer. The duty cycle varies from approximately 20% LO to 100% HI.
