Test Procedures
3.1. Access the Test menu and select FORWARD INPUT by using the SCROLL DISPLAY buttons. The IQDM
should indicate OFF when the Forward/Reverse switch is in the NEUTRAL or REVERSE position.
3.2. Place the Forward/Reverse switch in the FORWARD position. The IQDM should indicate that FORWARD
INPUT is ON. If the IQDM indicates any other reading, check vehicle wiring. See Wiring Diagrams on
page 12-2. Also check the 16-pin connector at the speed controller. See Test Procedure 9 – 16-Pin
Connector on page 12-23.
4. Test REVERSE INPUT.
4.1. Access the Test menu and select REVERSE INPUT by using the SCROLL DISPLAY buttons. The IQDM
should indicate OFF when the Forward/Reverse switch is in the NEUTRAL or FORWARD position.
4.2. Place the Forward/Reverse switch in the REVERSE position. The IQDM should indicate that REVERSE
INPUT is ON. If the IQDM indicates any other reading, check vehicle wiring. See Wiring Diagrams on
page 12-2. Also check the 16-pin connector at the speed controller. See Test Procedure 9 – 16-Pin
Connector on page 12-23.
5. If the IQDM displays readings other than those described above and the wiring is found to be correct, proceed to
the following procedure, Forward/Reverse Rocker Switch Test without the IQDM Handset.
Forward/Reverse Rocker Switch Test without the IQDM Handset
1. Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric Vehicles
on page 1-3.
2. Remove the two screws securing the rocker switch case to the vehicle body.
3. Remove switch from car. See Forward/Reverse Rocker Switch Removal on page 17-3.
4. Disconnect the three wires from the rocker switch. Using a multimeter set to 200 ohms, place the black (–)
probe on the white wire terminal 3 position on the rocker switch, and place the red (+) probe on the red wire
terminal 2 position. With the switch in NEUTRAL or REVERSE, there should be no continuity. With the switch in
FORWARD, there should be continuity. If the readings are incorrect, replace the switch.
5. Place the black (–) probe on the blue wire terminal 1 position on the rocker switch and place the red (+) probe on
the red wire terminal. With the switch in REVERSE, there should be continuity. If the readings are incorrect,
replace the switch.
TEST PROCEDURE 24 – Reverse Buzzer
See General Warnings on page 1-1.
1. Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric Vehicles
on page 1-3.
2. Remove the instrument panel. See Key Switch Removal on page 17-1.
3. Disconnect the orange/white and pink wires from the reverse buzzer.
4. Place the Tow/Run switch in the TOW position and connect the batteries. See Connecting the Batteries –
Electric Vehicles on page 1-3.
5. Place the key switch in the OFF position and the Tow/Run switch in the RUN position.
6. Using a multimeter set to 200 volts DC, place the black (–) probe on battery no. 4 (4 x 12-Volt battery set) or
battery no. 6 (6 x 8-Volt battery set) negative post and place the red (+) probe on the pink wire terminal end that
was disconnected from the reverse buzzer. The reading should be approximately 48 volts (full battery voltage).
6.1. If the voltage reading is correct, proceed to step 7.
6.2. If reading is zero volts, check pink wire continuity and Tow/Run switch. See Test Procedure 2 – Onboard
Computer Solenoid Lockout Circuit on page 12-15. See also Test Procedure 6 – Tow/Run Switch
on page 12-19.
6.3. If the continuity readings are not correct, repair or replace the pink wire.
6.4. If the continuity readings are correct, proceed to step 7.
