Grand Voyager V6-3.0L VIN 3 (1998)
RKE (Remote Keyless Entry) Interface
The body control module interfaces with the RKE receiver via a one-way serial bus interface. The RKE receiver sends a 0-5 volt pulse width
signal to the BCM depending on which button on the transmitter was pressed. The BCM controls the door lock/unlock relays and
arming/disarming of the Vehicle Theft Security System (if equipped). The RKE receiver is capable of retaining up to 4 individual vehicle access
codes (4 transmitters). If the PRNDL is in any position except park, the BCM will ground the interface wire thereby disabling the RKE.
The RKE module can be programmed via the DRBIII or customer programming method. The BCM will only allow programming mode to be
entered when the ignition is in the on position, the PRNDL is in park position, and the VTSS (if equipped) is in the disarmed mode.
Radio System
There are three radio systems available this year that will be on the CCD bus. They are the RBR, RBN and RAZ models. The main reason they are on the
bus is because of the radio remote controls in the steering wheel. They can control volume up/down, seek up, seek down and preset station selections.
These systems also communicate with the body control module and will set a specific code if there is a problem with the remote controls.
The RBR will have 4 speakers and the others will have 8 speaker locations (infinity sound). All of the 4 main quarter speakers have a built in amplifier.
The instrument panel and pillar speakers receive their signals from the quarter speakers. Depending on the manufacture some systems will have a
Front/Rear channel system and others will have a Left/Right channel system. If one of the main quarter speaker audio circuits experiences a short, the
other speakers on that channel will also shut down until the circuit is repaired. The radio will also set a trouble code, which is assessible with the DRB,
indicating which channel is effected.
Remote Keyless Entry (RKE) /Vehicle Theft Security System (VTSS)
This passive system is designed to protect against theft. The vehicle theft security system (VTSS) is part of the body control module, which monitors
vehicle hood, doors, liftgate, and ignition for unauthorized operation. The alarm activates by sounding the horn, flashing the headlamps, park and tail
lamps, and the VTSS indicator lamp, and providing an engine "no run" feature.
Passive arming occurs upon normal vehicle exit by turning the ignition off, opening the driver's door, locking the doors with the power lock, and closing
the driver's door or locking the doors with Remote Keyless Entry (RKE). Manual arming occurs by using the key to lock the doors after closing them.
The indicator lamp in the information center will flash for 15 seconds, showing that arming is in progress. If no monitored systems are activated during
this period, the system will arm. If the hood ajar switch is seen as closed circuit by the system, the indicator lamp will remain steadily lit during the
arming process, although the system will still arm.
When something triggers the alarm, the system will signal the headlamps, park lamps, and horn for about 3 minutes.
Tamper Alert - If the horn sounds three times when either front door or the liftgate is unlocked, it means the alarm was activated. Check the vehicle for
tampering.
Manual Override - The system will not arm if the doors are locked using the manual lock control (by hand) or if the locks are actuated by an inside
occupant after the door is closed.
When an unauthorized entry into the vehicle occurs, the VTSS sends a message via the CCD bus to the powertrain control module that it is not OK to
start the engine. The powertrain control module then zeroes out the pulse width to the fuel injectors after the engine has been started, thus shutting down
the engine (start and stall condition). The engine will not start until the system is disarmed.
To verify the system, proceed as follows:
1. Open the driver's door.
2. Remove the ignition key (but keep it in hand).
3. Lock the doors with the power lock switch.
4. Close the driver's door.
NOTE: After the doors are closed, locking the doors with RKE will also arm the system.
NOTE: If the VTSS indicator lamp flashed, the system is operational and verified. If not, there may be a problem with the system.
System initialization is accomplished by:
1. Opening the hood to ensure the hood ajar circuit is closed.
2. Rotating the key in liftgate cylinder to unlock/disarm position.
Arming/Disarming - Active arming occurs when the remote keyless entry transmitter is used to lock the vehicle doors, whether the doors are open or
closed. If one or more doors are open, the arming sequence is completed only after all doors are closed.
Passive disarming occurs upon normal vehicle entry (unlocking either front door or the liftgate with the key). This disarming also will halt the alarm once
it has been activated.
Active disarming occurs when the remote keyless entry transmitter is used to unlock the vehicle doors. This disarming also will halt the alarm once it has
