DISCUSSION:
This bulletin explains information related to electrical system changes for the 2002 Minivans
EVIC - TIRE PRESSURE MONITORING SYSTEM (TPMS)
The TPMS consists of the EVIC and four sensors in place of the tire air valves. The EVIC displays information related to the TPMS system. The system
monitors air pressure in the four road tires (excludes spare). Pressure in the spare tire is not monitored. The system alerts the driver when tire pressure
falls outside predetermined thresholds (pressure too low or too high). A message is then displayed on the Electronic Vehicle Information Center (EVIC)
located in the overhead console.
The TPMS uses radio and sensor technology to monitor tire air pressure levels. The battery operated sensors transmit tire pressure data to a receiver
located in the overhead console. These transmissions occur once every minute at speeds over 20 mph (32km/h).
If any tire's pressure has exceeded the low or high pressure threshold, the EVIC will display a message and a chime sounds. This message will be
displayed for the rest of the ignition cycle, or until the Low/High Tire pressure condition has been corrected. If the C/T, MENU, STEP or RESET button
is pressed, the message is replaced by the new message requested; however, if the Low/High Tire condition has not been corrected, the Low/High Tire
pressure message will be redisplayed. If a road tire is replaced by the spare, the TPM system will detect the swap and the message "SPARE TIRE IN
USE?" Y/N (along with a chime) will be displayed to confirm the swap.
CAUTION:
THE USE OF TIRE SEALANTS IS STRICTLY PROHIBITED FOR VEHICLES EQUIPPED WITH THE TIRE PRESSURE MONITORING
SYSTEM. TIRE SEALANT CAN CLOG TIRE PRESSURE SENSORS.
CAUTION:
WHEN SERVICING A WHEEL AND TIRE ASSEMBLY, DO NOT USE A STANDARD VALVE STEM CAP OR CORE IN A TIRE
PRESSURE SENSOR IN PLACE OF THE ORIGINAL EQUIPMENT STYLE SENSOR CAP AND CORE. TIRE PRESSURE SENSOR VALVE
STEM CAPS AND CORES ARE SPECIALLY DESIGNED FOR THE SENSORS.
CAUTION:
DO NOT ATTEMPT TO INSTALL A TIRE PRESSURE SENSOR IN A STEEL WHEEL OR AFTERMARKET WHEEL. USE TIRE PRESSURE
SENSORS IN ORIGINAL STYLE FACTORY WHEELS ONLY.
NOTE:
IF THE VEHICLE IS EQUIPPED WITH A TPM SYSTEM, MARK THE TIRE INDICATING THE LOCATION OF THE TIRE AND WHEEL
ASSEMBLY ON THE VEHICLE. UPON INSTALLATION, THE TIRE AND WHEEL ASSEMBLY WILL NEED TO BE INSTALLED ON THE
SAME CORNER OF THE VEHICLE WHERE IT WAS REMOVED OR THE TPMS SENSORS WILL NEED TO BE RETRAINED.
RADIOS
Connectors - All radios except the RAS radio have new connectors and ground strap locations.
RAS Radios - Vehicles equipped with RBB or higher content radios CANNOT BE downgraded to an RAS radio. If a vehicle with an RBB or higher
content radio is downgraded to an RAS radio, the radio light dimming feature will not work. This is due to a wiring change cannot be reprogrammed by
the DRBIII.
Rear Audio (Sales Code RDT) Operating Instructions - The Rear Seat Audio System allows passengers to listen to a different music source, through
headphones, other than what is playing through the vehicle's speaker system. A remote control is provided for functions such as changing stations, tracks,
