EEC 86.663 OF DEC. 1986
PARA. 9.7.3.5.5
FAULT SAFETY CIRCUIT CHECK PROCEDURE
EEC-certified vehicles are equipped with a safety system which will terminate any uncontrolled
power-on condition due to a fault in the electronic circuit.
This fault safety circuit should be checked during scheduled periodic maintenance inspections by
authorized service personnel.
·
PROCEDURE
Jack up the rear axle of the vehicle until the rear wheels spin free (see "Lift and Support Points,
11
Safety and General Information Section).
Disconnect the main traction battery cables.
The key switch must be turned off and battery cables disconnected. Be sure that the
rear wheels are clear of any foreign objects.
Place a 6-gauge jumper wire between the B- terminal and M- terminal of the PMC controller.
Reconnect the main traction battery cables.
Turn on the key switch and place the vehicle in the forward drive position.
Depress the accelerator pedal down approximately half of the distance to the floor.
Do not exceed 80% of the accelerator travel.
If the rear wheels turn, the PMC fault safety circuit is defective and the PMC controller
must be replaced.
If the rear wheels do not turn, then the fault safety circuit is functioning correctly.
Turn off the key switch.
Disconnect the main traction battery cables.
Remove the jumper wire between the B- and
M-
terminals.
Reconnect the main traction battery cables and lower the vehicle.
