LH
TRANSMISSION RANGE
INDICATOR (PRNDL)
DESCRIPTION
The shift position indicator is located in the instru-
ment cluster. It indicates the position of the manual
valve lever by illuminating an LED located under the
P, R, N, D, 3, or L (or Autostick) gear symbol.

OPERATION

The Transmission Range Sensor (TRS) sends a sig-
nal to the Powertrain Control Module (PCM) regard-
ing the position of the manual valve lever. The PCM
converts this signal into a Shift Lever Position (SLP)
and sends the information to the Body Control Mod-
ule (BCM) and the instrument cluster.
DIAGNOSIS AND TESTING - TRANSMISSION
RANGE INDICATOR
The transmission range sensor (on the valve body)
sends a signal to the PCM on the position of the
transaxle manual valve lever. The PCM receives the
switch signal and processes the data. The PCM sends
the Shift Lever Position (SLP) information to the
BCM via the communication bus. The BCM then out-
lines the appropriate transmission range indicator in
the instrument cluster.
If a problem arises with the transmission range
indicator, refer to TRANSMISSION RANGE INDI-
CATOR TEST , and the proper Body Diagnostic Pro-
cedures manual if the problem still exists.
To replace the transmission range indicator (Refer
to 23 - BODY/INTERIOR/CENTER
BEZEL - REMOVAL).
