IQ SYSTEM TROUBLESHOOTING Test Procedures
11
1. Disconnect the battery cables and discharge the controller as instructed. See WARNINGS “To avoid
unintentionally starting...” and “After disconnecting the batteries, wait 90 seconds...” in General
Warnings on page 1-1.
2. Place chocks at the front wheels and lift the rear of the vehicle with a chain hoist or floor jack. Position jack
stands under the frame rails just forward of each spring mount.
See WARNING “Lift only one end...” in
General Warnings on page 1-1.
3. Disconnect the 16-pin connector at the speed controller.
4. Using a multimeter set for 200 volts DC, insert the red (+) probe of the multimeter into pin 5 (light blue wire) of the
16-pin connector.
See following CAUTION. Using an alligator clip, connect the black (–) probe to the B– terminal
of the speed controller (Figure 11-11, Page 11-23) .
CAUTION
• Do not fully insert probes into the 16-pin plug. Doing so can result in a poor connection.

5. Place the Tow/Run switch in the TOW position and connect the battery cables, positive (+) cable first. Tighten
battery terminals to 110 in-lb (12.4 N·m).
6. Place the Tow/Run switch in the RUN position.
7. The multimeter should indicate zero volts DC at this time.
8. While monitoring the multimeter, plug the battery charger into the vehicle charger receptacle.
9. After a short delay, the onboard computer should power-up (come out of sleep mode), charger relay should click,
and the ammeter on the charger should indicate that the vehicle batteries are being charged.
10. The multimeter should indicate zero volts DC while the charger is connected to the vehicle.
11. While observing the multimeter, disconnect the DC plug from the vehicle charger receptacle.
12. The multimeter should indicate full battery voltage when the charger is not connected to the vehicle.
13. If any other reading is obtained, check the following items:
– Continuity of the wires in the wire harness
– Onboard computer for proper operation. See Test Procedure 19 – Onboard Computer Gray Wire on
page 11-30.
– Tow/Run switch for proper operation. See Test Procedure 6 – Tow/Run Switch on page 11-17.
