Diagnosis (Cont'd)
The Transaxle Range Switch (TRS) is located on the
top of the transaxle, as shown in Figure 23. The TRS
is a mechanical multi-position switch with 6 sliding
contacts, four selector position switches, one reverse
switch and one switch for positions P/N, for starting
control.
The only ignition voltage sent to the switch goes in at
terminal 10 and goes through only the reverse switch,
as shown in Figure 24. Voltage exits through terminal
8 and is sent to the reverse lamps and the TCM. This
is easy to diagnos using a volt meter.
The remainder of the switches provide a ground
signal for the starter relay through the P/N switch and
ground signal to the TCM through the position
switches, as shown in Figure 24. These switches
must be checked with the DVOM set to Ohms. Notice
in Figure 24 that terminals 3 and 4 provide the ground
into the switches. Use the Ohm meter across
terminals 4 and 2 to check for the Park and Neutral
positions, as shown in the chart provided in Figure 24.
With the Ohm meter on terminal 3, you should have
continuity across the terminals shown in the chart in
Figure 24, related to the position of the gear selector
lever.
