When NO is selected, the distance until the next PERFORM SERVICE message is reduced by the accumulated distance since the last pervious message.
4. EVIC exits programming mode and returns to its normal operation mode when the C/T button is depressed or when the end of the programmable feature menu list is reached, whichever occurs first.

SERVICE REMINDER INDICATOR LIGHT RESET - PROCEDURE 1

A mileage counter activates the service reminder indicator between 12,000 and 30,000 mile intervals, depending on whether mechanical or electronic type is used. On 1987 Dakota models, mileage counter in the odometer will illuminate reminder light at 52,500, 82,500 and 105,000 miles.

The electronic type uses a 9-volt battery which supplies power to the electronic counter, preventing memory loss when vehicle battery is disconnected.

Note. Vehicle battery must be connected during resetting procedure to prevent power loss to memory.

To reset electronic type, locate Green, Red, White or Tan plastic case behind instrument panel in lower left cluster area. Slide case from bracket and open cover. Remove 9-volt battery, and insert a small rod or screwdriver into hole in switch, closing contacts. Replace battery with a new 9-volt alkaline type. Close case. Slide case back into bracket. (Scheme 8)

Note. Some models use a non-resettable mileage counter. Replace it with a resettable type.

SERVICE REMINDER INDICATOR LIGHT RESET - PROCEDURE 2

Every 7500 miles, a Vehicle Maintenance Monitor (VMM) will illuminate a SERVICE interval reminder indicator light. This indicates regular maintenance is due. After required service is performed, press RESET button on dash below VMM display. Hold button until a beep is heard. VMM display will now be clear.

SERVICE REMINDER MESSAGE RESET - PROCEDURE 1

Every 7500 miles or 12 months which ever comes first, a service reminder message on Electronic Vehicle Information Center (EVIC) display will illuminate, indicating an oil change is due. The EVIC is an optional accessory located in the overhead console.

Pressing INFO button with the ignition on will activate a MONITORED SYSTEMS OK message on the display if all systems are operating properly. If service is required, SERVICE REMINDER message will be displayed. Pressing the RESET button after message has been displayed will clear the message.

SERVICE REMINDER MESSAGE RESET - PROCEDURE 2

Every 7500 miles or 12 months which ever comes first, a service reminder message on Electronic Vehicle Information Center (EVIC) display will illuminate, indicating an oil change is due. The EVIC is an optional accessory located in the overhead console.

Pressing INFO button with the ignition on will activate a MONITORED SYSTEMS OK message on the display if all systems are operating properly. If service is required, SERVICE REMINDER message will be displayed. To clear message, press INFO button and within 5 seconds, press SET button.

TPMS RESET - PROCEDURE 1

Note. In a low tire pressure siuation, the TPMS indicator light (and message) will turn OFF only after the tires are inflated to the vehicles recommended cold placard pressure value. The vehicle may need to be driven for up to 20 minutes above 20 mph (32 km/h) in order for the TPMS to determine that the inflation pressures are correct.

Once a sensor has been replaced and vehicle has remained stationary for more than 20 minutes, drive vehicle for a minimum of 20 minutes while maintaining a continuous speed above 20 mph (32 km/h). During this time, the system will learn the new sensor ID code and will clear any DTCs automatically. If a sensor cannot be trained, see appropriate manufacturer service information.

Note. The sensor IDs can also be programmed using the TPM-RKE Analyzer Tool. Scan each TPM sensor at each road wheel, and store each Sensor ID in the correct location (Left Front, Left Rear, Right Front, and Right Rear). Connect the TPM-RKE Analyzer Tool to the Scan Tool. Then follow the programming steps outlined in the diagnostic Scan Tool for "Program Tire Pressure Sensor ID w/ TPM Tool".

TPMS Indicator Reset

Once a sensor has been replaced and vehicle has remained stationary for more than 20 minutes, drive vehicle for a minimum of 10 minutes while maintaining a continuous speed above 20 mph (32 km/h). During this time, the system will learn the new sensor ID code and will clear any DTCs automatically. If a sensor cannot be trained, see appropriate manufacturer service information.

TPMS RESET - PROCEDURE 3

Note. If a tire is changed (tire rotation), one or more tire pressure sensors fail, or if TPM module is replaced, the TPM system needs to relearn tire pressure sensor IDs. The procedure is similar to Tire Sensors Programming in TPMS RESET - PROCEDURE 2.

When tire pressure is low, the "Low Tire" Pressure Indicator Lamp signal circuit will be pulsed to ground by the TPM module for two seconds on and then two seconds off, over and over. The BCM will then illuminate the "Low Tire" Pressure Indicator Lamp at the same rate and sound the audible chime as one single long tone.

When tire pressure is critical, the low tire pressure warning lamp signal circuit will be pulsed to ground by the low tire pressure warning module for one second on and then one second off, over and over. The BCM will then illuminate the "Low Tire" Pressure Indicator Lamp and sound the audible chime at the rate of one second on and one second off.

In either case, the TPM module will continue to pulse to ground the "Low Tire" Pressure Indicator Lamp signal circuit until the sensor/transmitter(s) transmits a pressure above the calibrated thresholds (and car is then driven above 20 mph (32 km/h)) or the ignition is turned off. If the conditions has not been corrected when the ignition is turned off, the indicator lamp will remain off when the ignition is turned on again until the vehicle reaches a speed of approximately 20 mph (32 km/h).

Note. In the event a diagnostic trouble code (DTC) is set, the "Low Tire" Pressure Indicator Lamp will illuminate continuously until the ignition is turned off. A low tire pressure condition cannot set a diagnostic trouble code (DTC).

TPMS RESET - PROCEDURE 4

The TPMS will not turn off the indicator lamp until the tire pressure is at or above the Low Pressure (lamp) OFF threshold. The system will automatically update and the TPM indicator lamp will extinguish once the updated tire pressures have been received.

Note. If a tire pressure sensor has been replaced, the TPM system needs to relearn tire pressure sensor IDs.

Wireless Control Module (WCM): The WCM automatically learns and stores new sensor IDs while driving "within 10-20 minutes continuously above 15 mph (24 km/h)" after a sensor has been replaced. The learning sequence will initiate when the vehicle has been stopped for more then 20 minutes.

A new sensor ID can also be programmed directly into the WCM by using an RKE-TPM Analyzer in conjunction with a Scan Tool. Scan each TPM sensor at each road wheel, and store each Sensor ID in the correct location. (Left Front, Left Rear, Right Front, and Right Rear) Connect the TPM-RKE Analyzer Tool to the Scan Tool. Then follow the programming steps outlined in the diagnostic Scan Tool for "Program Tire Pressure Sensor ID w/ TPM Tool"

For further information, refer to the Owners Manual or the Appropriate Diagnostic Information.

TPMS RESET - PROCEDURE 5

There are two tire pressure monitoring systems available, a base system and a premium system. The base system does not specify how many tires are low or where they are located. The premium system does indicate which tire is low. Sensor types are the Tire Pressure Monitoring (TPM) module for the 2500/3500 series, or the Wireless Ignition Node (WIN) for the 1500 series.

Base Tire Pressure Monitoring System

The TPMS will not turn off the indicator lamp until the tire pressure is at or above specified tire pressure. The system will automatically update and the TPM indicator lamp will extinguish once the updated tire pressures have been received.

Premium Tire Pressure Monitoring System

If the TPMS detects that the tire pressure in any road tire is going low, a chime will sound and the indicator lamp will turn on. In addition to the chime and lamp, a graphic display of the pressure value(s) and position of the low tire(s) will flash in the Electronic Vehicle Information Center (EVIC). Once pressure in the suspect tire(s) raises above the specified tire pressure, and the TPM module receives a valid transmission from the sensor the lamp will go out. If a system fault is detected due to a missing sensor signal, in addition to a chime and a indicator lamp flashing, a "Check TPM System" text message will be displayed in the instrument cluster, and the tire pressure graphic display will display "- -" in place of the pressure value. After the flash sequence the TPM indicator lamp will remain illuminated. The system will return to normal once the TPM module receives a valid transmission from that sensor location. If a system fault is detected, the indicator lamp will flash on/off for 75 seconds and then remain on solid.

Base and Premium Systems

Note. If a tire pressure sensor has been replaced, the TPM system needs to relearn tire pressure sensor IDs.

The WIN or TPM automatically learns and stores the sensor IDs while driving "within 10-20 minutes continuously above 15 mph (24 km/h)" after a sensor has been replaced. The learning sequence will initiate after the vehicle has been stopped for more than 20 minutes.

A new sensor ID can also be programmed directly into the WIN or TPM module by using a RKE-TPM Analyzer in conjunction with a Scan Tool. Once the new sensor ID has been programmed, the vehicle will need to be driven above 15 mph until the fault is no longer active (lamp extinguishes) and display is updated (for up to 20 minutes).

Note. The matching full size spare wheel and tire assembly (if equipped) has a TPM sensor. The spare can be used in place of any of the four road tires. The TPMS will only monitor the pressure in the full size spare when it is used in place of a road tire. Otherwise, a spare with pressure below the low-pressure limit will not cause the TPMS indicator light to illuminate or the chime to sound.

TPMS RESET - PROCEDURE 6

Note. If tires have been rotated or a tire pressure sensor has been replaced, the tire pressure sensors must be retrained. Refer to the following procedure to program the module for identification of one new or all tire pressure sensor/transmitters.

Note. The vehicle's tires must not have been rotated above 5 mph (8 km/h) in the last two minutes prior to programming.

1. Connect a DRBIII® scan tool to the vehicle's diagnostic connector beneath the instrument panel, to the right of the steering column.
2. Access the Chassis System using the DRBIII.
3. Once in the Chassis System, select Tire Pressure Monitor, followed by Miscellaneous.
4. Select the appropriate function from the next screen displaying the following options: Program LF Pressure Sensor Program RF Pressure Sensor Program RR Pressure Sensor Program LR Pressure Sensor Program Module (4 Sensors) Monitor
5. Place a magnet (or special tool 8821), at the valve stem for that wheel as directed by the DRBIII. If the Program Module function has been chosen, the DRBIII will direct you to the left front wheel pressure sensor/transmitter first.
6. When that wheels pressure sensor/transmitter has been programmed, the DRBIII will display Program Transmitter Complete or will automatically direct you to the next wheel sensor/transmitter to be programmed.
7. Remove the magnet and if programming the entire module, move the magnet to each of the remaining wheels as directed by the DRBIII. Each sensor/transmitter will automatically sense the presence of the magnet and begin programming.
8. Once Program Transmitter Complete is displayed, exit the program function screen.
9. Verify that the module programming is complete by looking at the tire pressure sensor/transmitter ID's in the Sensor Display using the DRBIII.
