Transmission Mode Indicator - A/T: Description and Operation
With the ignition switch in ON (II) or START (III), voltage is applied to the A/T gear position indicator. The A/T gear position switch provides a
ground for each position. As an input is grounded, its indicator light comes ON. If you select R, for example, ground will be applied to the input of the
A/T gear position indicator, and the R indicator will come ON.
With the headlight switch in PARK or HEAD, voltage is applied to the RED/BLK wire terminal. This changes the indicator panel illumination from
fixed to controlled by the dash lights dimmer input through the RED wire.
When the powertrain (all except '97 3.0L) or transmission ('97 3.0L) control module (PCM or TCM) detects an abnormality in the automatic
transmission control system, or when you request diagnostic trouble codes through the service check connector, the PCM (all except '97 3.0L) or TCM
('97 3.0L) will make the D4 indicator light blink.
