TEST PROCEDURE 18 – REBOOTING THE ONBOARD COMPUTER
See General Warning, Section 10, Page 10-1.
It is possible the Onboard Computer (OBC) can become “locked up,” causing the OBC solenoid lockout circuit
to malfunction. If this condition is suspected, restart the computer as follows:
1. Disconnect the battery cables as instructed.
See WARNING “To avoid unintentionally starting...” in
General Warning, Section 10, Page 10-1. See following NOTE.
2. With the Tow/Run switch in the TOW position, connect the battery cables, positive (+) cable first. Tighten
battery terminals to 110 in-lb (12.4 N·m) and coat terminals with Battery Terminal Protector Spray (CCI
P/N 1014305) to minimize corrosion.
3. Place Tow/Run switch in the RUN position.
4. Test drive the vehicle. If the problem has been fixed, the vehicle will function normally. If the problem still
exists, refer to Wiring Diagrams beginning on page 11-2.
TEST PROCEDURE 19 – BATTERY WARNING LIGHT
See General Warning, Section 10, Page 10-1.
1. Reboot the OBC and drive the vehicle a short distance. When vehicle is first driven, the battery warning
light should illuminate for 2-3 seconds.
See Test Procedure 18 – Rebooting the Onboard Computer
If the battery warning light does not illuminate when rebooting the OBC, proceed to step
2. Turn key switch OFF, place Tow/Run switch in TOW and place Forward/Reverse rocker switch in NEU-
TRAL.
3. Disconnect the six-pin connector at the OBC.
4. Remove the wedge lock from the six-pin connector housing that is connected to the vehicle wire harness.
Remove the brown/white wire from the connector plug.
5. Use a jumper wire with an alligator clip at each end and connect one alligator clip to the negative post
of battery no. 2 and the other alligator clip to the brown/white wire terminal socket that was removed from
the six-pin connector plug.
6. Install the wedge lock in the six-pin connector housing and reconnect the six-pin connector plug. Place
the Tow/Run switch in the RUN position and the battery light should illuminate. If the light does not illu-
minate, replace the battery warning light assembly.
