Key Switch and MCOR 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 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.
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. See Plugging the Handset into the Vehicle on page 23-1.
4. Test the key switch.
4.1. Access the Monitor 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 MCOR 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 MCOR limit switch with the IQDM handset.
5. Test the MCOR limit switch.
5.1. Select FOOT INPUT on the Monitor 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 pedal group for proper adjustment. See Accelerator and Brake Pedal Group Section.
6.2. Check the wiring of the key switch and MCOR. See Wiring Diagrams on page 22-2.
6.3. Check the continuity of the key switch wires and the MCOR limit switch wires.
7. If the problem was not found, proceed to the following procedure.
Key Switch and MCOR Limit Switch Circuit Test without the IQDM Handset
1. Disconnect the batteries and discharge the controller. See Disconnecting the Batteries – Electric Vehicles,
Section 1, Page 1-4.
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. 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 center dash panel. See Key Switch Removal on page 24-1.
4.2. Set a multimeter to 200 ohms. Place the red (+) probe on the key switch terminal with the blue wire. Place
the black (–) probe on the key switch terminal with the green wire.
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.
4.5. If any other reading is obtained, replace the key switch. See Key Switch Removal on page 24-1.
