7. The multimeter should indicate zero volts DC at this time.
8. While monitoring the multimeter, slowly press the accelerator pedal and hold the pedal at approximately
20% of full travel.
9. After a short delay, the onboard computer should power-up (come out of sleep mode).
10. The multimeter should indicate full battery voltage (approximately 48 volts) when the accelerator pedal
is pressed.
11. While observing the multimeter, release the accelerator pedal.
12. The multimeter should indicate zero volts when the accelerator pedal is not pressed.
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 11 – Onboard Computer Gray Wire
and Fuse on page 21-28.
• Tow/Run switch for proper operation. See Test Procedure 6 – Tow/Run Switch on page 21-15.
• Key switch and MCOR limit switch for proper operation. See Test Procedure 8 – Key Switch and
MCOR Limit Switch Circuit on page 21-16.
• Ensure that the pedal group is adjusted correctly. See Pedal Group Adjustment – Electric Vehicles
on page 5-16.
Test Procedure 9D – Pin 7
See General Warning on page 1-1.
Pin 7 in the 16-pin connector provides a connection point for the reverse buzzer to the speed controller.
1. Disconnect the battery cables as instructed. See WARNING “To avoid unintentionally starting...” in
General Warning 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 crossmember between the spring mount and side stringer, just forward of
each rear wheel.
See WARNING “Lift only one end...” in General Warning on page 1-1.
3. Disconnect the 16-pin connector at the speed controller.
4. Place a jumper wire with an alligator clip between the B– terminal of the speed controller (use alligator
clip for this connection) and pin 7 (orange/white wire) of the 16-pin connector (Figure 21-8, Page 21-23) .
See following CAUTION.
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 reverse buzzer should sound when the Tow/Run switch is in the RUN position.
8. If any other activity is observed, check the following items:
• Continuity of the wires in the wire harness
• Reverse buzzer for proper operation. See Test Procedure 16 – Reverse Buzzer on page 21-31.
• Tow/Run switch for proper operation. See Test Procedure 6 – Tow/Run Switch on page 21-15.
