TEST 8 SHIFT INDICATOR NOT WORKING (TRANSMISSION SWITCH)
Operation:
The Instrument cluster sends a signal through the White wire
to the resistor module. This signal completes it's path on the
Brown/Red wire through the transmission switch. Depending
on the transmission switch position, the Instrument cluster
interprets the resistance reading and displays the corre-
sponding shift position in the LCD panel.
Testing:
Use the diagram provided to test the continuity loop at each
of the shift points with a multi- -meter. NOTE: The Instrument
cluster contains this diagnostic feature.
