Repair and Service Manual

Read all of Section B and this section before attempting any procedure. Pay particular attention to all Notes, Cautions and Warnings.

Drain the stored energy from the controller.

Make sure that the Run/Tow switch is in the

Run position, turn the key to reverse and allow

the reverse warning indicator to run down.

The controller is a solid state unit activated by a sole-
noid. The solenoid is hard wired to the electrical harness
and mounted to the controller heat sink. The controller is
located under the seat on the passenger side of the
vehicle. To access the controller, raise and remove the
seat bottom.

1. Disconnect the battery cable at the negative (-), BL-,

battery terminal using an insulated wrench.

2. Drain the stored energy from the controller. Place the

Run/Tow switch in the Run position, turn the key
switch to reverse, wait for the reverse warning indica-
tor to become silent, turn the key switch to the off posi-
tion and remove the key from the switch.

3. Remove two Torx head screws (4) securing the con-

troller splash shield to the rear body and the christmas
tree rivet (2) securing the splash shield to the control-
ler heat sink; position splash shield off to one side to
allow access to the controller.

4. Disconnect the Red positive (+) battery cable from the

upper terminal of the solenoid.

5. Disconnect the Red wire from the controller B+ termi-

nal to the lower terminal of the solenoid.

6. Remove two hex head bolts (7) securing the solenoid

to the controller heat sink, place the solenoid off to
one side out of the way.

The original solenoid is

hard wired into the electrical harness.

7. Disconnect the 2 pin connector (14) from the wire har-

ness.

8. Disconnect the 3 pin connector (12) from the resistor

control (13) connector.

9. Disconnect the 23 pin connector (9) from controller by

lifting up on the locking tab and pulling the connector
housing away from the controller.

10. Disconnect the three wires (8) from the electric motor

to terminals U, V and W by removing the three control-
ler terminal screws (11).

11. Disconnect the negative (-) battery wire (3) from the B-

terminal by removing the terminal screw (11).

12. Remove the front two hex head bolts (10) securing the

controller assembly to the floorboard and loosen the
rear hex head bolt (10). Slide the controller towards
the front of the car and lift it out.

13. To install the controller, position it on the floorboard;

making sure that all wires are not pinched or under the

controller feet; and slide it to the back aligning the slot
under the head of the hex head bolt (10). Install the
two hex head bolts (10) in the holes at the front of the
controller base. Torque all three hex head bolts as
specified in the torque table.

14. Connect the three wires from the electric motor. Blue

to the W terminal, Yellow to the V terminal and Green
to the U terminal. Install the terminal screws finger
tight, then torque as specified.

Do not over tighten

the terminal screws (11).

15. Connect the black wire (3) from the B- terminal to the

negative (-), BL-, battery terminal.

Do not over

tighten the terminal screw (11).

16. Install the solenoid on the controller heat sink using

two hex head bolts (7). Make sure that the black wires
from the solenoid to the wire harness are located at
the top of the solenoid.

17. Install the Red wire to the B+ terminal of the controller.

(Do not over tighten the terminal screw (11).
