perform the following tests:
•

If you do not know how to test for continuity, refer
test to a qualified technician.
•
This should read as an open circuit. If it
reads as a short, then one of the following
has occurred:
A) The reverse solenoid is shorted.
B) The wire connected to the PMC 'M-'
terminal is shorted to the wire connected
to the motor 'S1' terminal.
Stop trouble shooting here and repair the
problem. When the repair is completed,
completely retest the vehicle before lowering
the drive wheels to the ground

unanticipated problem or have made an error during testing. It is important to review the
trouble shooting steps that have led to this point. The tests may need to be repeated.
