Prowler V6-3.5L VIN G (1999)
Two transmitters are provided with each vehicle, but the RKE module is capable of accommodating four transmitters. The transmitters can be
programmed by using the DRB III or the customer can add a transmitter providing a valid previously programmed transmitter exists. This is
accomplished by pressing and holding the programmed transmitter unlock button from 4 to 10 seconds and then while still pressing the unlock
button, press and release the panic button. This will put the BCM in programming mode. The customer will have approximately 30 seconds to
Remote Keyless Entry (RKE) (standard equipment)
The body control module interfaces with the remote keyless entry receiver module via a one-way serial bus interface. The RKE module is
located under the left side of the instrument panel top cover. It does not actuate relays directly but receives the signal from the transmitter and
then communicates with the BCM.
Two transmitters are provided with each vehicle, but the RKE module is capable of accommodating four transmitters. The transmitters can be
programmed by using the DRB III or the customer can add a transmitter providing a valid previously programmed transmitter exists. This is
accomplished by pressing and holding the programmed transmitter unlock button from 4 to 10 seconds and then while still pressing the unlock
button, press and release the panic button. This will put the BCM in programming mode. The customer will have approximately 30 seconds to
press any button on each transmitter thereby programming that transmitter to the receiver. A technician with the DRB Ill can reprogram any
RKE module providing VTSS is disarmed.
The RKE system, operated by the transmitter, has three modes of operation controlled by three buttons.
-
Unlock button: Pressing the unlock button once will unlock the driver's door, disarm VTSS and illuminate the interior lamps. Pressing the
unlock button twice within 5 seconds unlocks both doors.
-
Lock button: Pressing the lock button locks all doors and sounds the horn once (if horn chirp is enabled).
-
Panic button: When the panic button is pressed the horn is pulsed, the headlamps and marker lamps are flashed and the interior lamps are
turned on. This will last for up to 3 minutes or until the panic button is pressed again or the ignition is turned on. The panic feature only
works when the ignition is in the off position.
*Horn chirp: When all doors are closed and a lock command is sent by the RKE transmitter, a horn chirp will be heard. The horn chirp is
also customer programmable by pressing and holding the lock button on the transmitter for 5 seconds and then while still holding the lock
button, pressing the unlock button and releasing both. This will toggle (enable/disable) the horn chirp.
VEHICLE COMMUNICATION
The Chrysler Collision Detection multiplex system (CCD bus) consists of a twisted pair of wires. These wires run from one module to another.
They receive and deliver coded information between the modules. The information is coded to identify the message as well as the importance of
the message. When there are multiple messages trying to access the CCD bus at one time, the code determines the message that has higher priority,
which is then allowed to access the bus first.
The two wires of the twisted pair that make up the CCD multiplex system are called "bus +" (bus plus) and "bus-" (bus minus) respectively. Each
wire has a measurable voltage level of roughly 2.5 volts. In order to maintain the 2.5 volts on each line and provide a means of transportation for
the coded messages, there is a "voltage divider network". This network consists of some modules with bias and some with termination. Bias is the
part of the voltage divider network that places both bus + and bus - at 2.5 volts. Termination in the circuitry is required to complete the voltage
divider network and also provides some electromagnetic protection for the bus.
NOTE: Communication over the bus is essential to the proper operation of the vehicle's on-board diagnostic systems and the DRB. Problems with
the operation of the bus or DRB must be corrected before proceeding with diagnostic testing. If there is a problem, refer to the Vehicle
Communications.
Bus Failure Messages
Short to Battery - Either or both of the bus wires are shorted to the battery potential.
Short to 5 Volts - Either or both of the bus wires are shorted to a 5-volt potential.
Short to Ground - Either or both of the bus wires are shorted to ground or a specific ground may be open.
Bus (+) & Bus (-) Shorted Together - The two bus wires are shorted together.
No Termination - The bus system has lost connection with all of its terminators.
Bus Bias Level Too Low - Either or both of the bus wire potentials are significantly below their normal 2.5 volts.
Bus Bias Level Too High - Either or both of the bus wire potentials are significantly above their normal 2.5 volts.
No Bus Bias - The bus system has lost connection with termination and/or bias.
Bus (+) Open - The bus (+) wire has lost connection with termination and/or bias.
Bus (-) Open - The bus (-) wire has lost connection with termination and/or bias.
Not Receiving Bus Messages Correctly - The DRB cannot communicate over the bus and does not know why.
VEHICLE THEFT SECURITY SYSTEM (VTSS)
The vehicle theft security system is controlled by the body control module and is standard equipment on all Prowler vehicles. It monitors the
doors, decklid, hood and ignition circuit to determine if the alarm should be triggered and engine disabled. When the system is armed, the BCM
removes the ground from the decklid release switch thereby preventing a thief from accessing the trunk area.
When the alarm is triggered, the engine becomes disabled. In addition the horn is pulsed, the headlamps and marker lights will flash for (3) three
minutes. After the 3 minute alarm has expired the BCM will return to an armed state and ignore the input(s) that triggered the initial alarm, unless
