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, otherwise continue with the
next test.

•

Check continuity from the motor ‘A2’
terminal to the wire that was connected
to the motor ‘S2’ terminal. DO NOT make
this test to the ‘S2” terminal, just the wire.

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 forward solenoid is shorted.
B) The wire connected to the motor ‘S2’

terminal is shorted to the wire connected
to the motor ‘A2’ terminal.

C) The wire connected to the motor ‘S2’

terminal is shorted to the wire connected to the PMC ‘A2’ 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, otherwise continue with the
next test.

With the key-switch on and the F&R switch in forward, depress the accelerator pedal
and perform the following tests:

Check continuity from the wire that was

connected to the PMC ‘M-’ terminal to
the wire that was connected to the motor
‘S2’ terminal.

If you do not know how to test for continuity,
refer test to a qualified technician.
