Mechanical Instrument Cluster (MIC)
The body control module sends the angular position of the gauges, the status of all CCD indicator lamps, the status and dimming of the mechanical
instrument cluster (MIC) over the CCD bus when the ignition is in the "off" (unlock), "run", or "start" positions.
The PRNDL (VF, if equipped) and odometer/trip displays work when the ignition is in the "off" (unlock), "run", or "start" positions; all other MIC
features work only when the ignition is in the "run" position.
On transition of the ignition from the "off" to the "run" position, a bulb check is performed. This consists of activating all CCD-controlled indicator
lamps and all VF display segments for approximately 2-4 seconds. The PRNDL bulb check is aborted if the gear selector is moved from the PARK
position, or if the engine exceeds 450 rpm.
Positive Temperature Coefficient (PTC)
The wiring to several electrical systems on this vehicle will be protected using PTC (Positive Temperature Coefficient) devices.
The PTCs are located in the junction block and act as non-replaceable resettable fuses.
An overload such as a short circuit will cause the device to trip and limit the current to less than an amp, protecting the wire.
To reset the device all current must be removed (similar to a remote reset circuit breaker).
-
With current removed the PTC will automatically reset in about 20 seconds.
Power Door Lock System
When the BCM receives an input for a lock request (door lock switch, RKE, or door key cylinder switch (only with VTSS)), it will ground the
lock relay coil for a specified amount of time ranging from 62 msec to 1 second. If the request is there beyond 1 second, the BCM considers the
door lock signal stuck and will turn the relay coil off. Once a door lock signal is stuck, the signal input for that door is ignored until the stuck fault
disappears. The unlock signal operates in the same fashion as the lock signal. The door lock switches provide a variable amount of resistance
thereby dropping the voltage of the multiplexed (MUX) circuit and the BCM will respond to that command.
A new feature for this vehicle is the use of PTC's (Positive Temperature Coefficient devices) to protect the door lock circuits. When a short in one
of the doors occurs, it also will cause one of more of the other doors to become inoperative.
Other power door lock features:
Sliding Door Memory Lock - When the BCM receives an input for a lock request and a sliding door is open, the BCM will turn on the lock relay
as described above, and will turn it on again when all sliding doors are closed. NOTE: If the BCM receives an unlock input before a sliding door is
closed this action will cancel the memory lock.
