Stratus V6-2.5L VIN H (1997)
Shift Indicator: Description and Operation
CIRCUIT OPERATION
PRNDL (Electronic)
On vehicles equipped with an automatic transmission an electronic PRNDL is used to indicate to the operator gearshift position.
When the ignition switch is in the OFF (unlock), RUN, or START position the Body Control Module (BCM) transmits a message over the CCD
Bus instructing the instrument cluster to illuminate the proper display
The BCM receives its information over the CCD Bus from the Transmission Control Module (TCM). When the ignition switch is moved to the
RUN position, the BCM instructs the instrument cluster to illuminate all segments of the PRNDL as a check.
PRNDL Illumination
The PRNDL illumination is handled by a Light Emitting Diode (LED) and receives power on the E2 circuit from the Body Control Module
(BCM). This circuit is HOT when the operator has turned the headlamp switch to the PARK or ON position. Lamp intensity is controlled by the
input of the dimmer switch to the BCM on circuit E19.
Ground for the LED is provided by the Z1 circuit. This circuit terminates at the instrument panel left side cowl after passing through the ground
joint in the junction block.
