Test Procedures
TEST PROCEDURE 8 – Key Switch and Throttle Position Sensor Limit Switch Circuit
See General Warnings on page 1-1.
Key Switch and Throttle Position Sensor Limit Switch Circuit Test with the IQDM Handset
1. 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.
2. Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
3. Connect the IQDM to the vehicle.
4. Test the key switch.
4.1. Access the Test menu and select KEY INPUT by using the SCROLL DISPLAY buttons. The IQDM should
indicate OFF when the key switch is in the OFF position.
4.2. While monitoring the IQDM display screen, turn the key switch to the ON position. The IQDM should
indicate ON.
4.3. If the IQDM does not indicate that KEY INPUT is ON when the key switch is in the ON position, proceed to
the following procedure, Key Switch and Throttle Position Sensor Limit Switch Circuit Test without
the IQDM Handset. If the key switch functions as described, proceed to the following step. See following
NOTE.
NOTE: The key switch MUST function properly in order to test the throttle position sensor limit switch with the IQDM
handset.
5. Test the throttle position sensor limit switch.
5.1. Select FOOT INPUT on the Test menu by using the SCROLL DISPLAY buttons on the IQDM.
5.2. The IQDM should indicate that FOOT INPUT is OFF when the accelerator pedal is not pressed, regardless
of the key switch position.
5.3. With the key switch in the ON position, press the accelerator pedal. The IQDM should indicate that FOOT
INPUT is ON when the accelerator pedal is pressed.
6. If any reading is obtained that is not described in steps 4 and 5, perform the following steps:
6.1. Check the wiring of the key switch and throttle position sensor. See Wiring Diagrams on page 11-2.
6.2. Check the continuity of the key switch wires and the throttle position sensor limit switch wires.
7. If the problem was not found, proceed to the following procedure, Key Switch and Throttle Position Sensor
Limit Switch Circuit Test without the IQDM Handset.
Key Switch and Throttle Position Sensor Limit Switch Circuit Test without the IQDM Handset
1. Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric Vehicles
on page 1-3.
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. Turn the key switch to the OFF position and place the Forward/Reverse switch in the NEUTRAL position.
4. Test the key switch.
4.1. Remove the instrument panel. See Key Switch Removal on page 17-1.
4.2. Using a multimeter set to 200 ohms, place the red (+) probe on the key switch terminal with the blue wire.
Place the black (–) probe on the other key switch terminal.
4.3. With the key switch in the OFF position, the multimeter should indicate that continuity is not present.
4.4. With the key switch in the ON position, the multimeter should indicate that continuity is present.
