ELECTRICAL SYSTEM AND TESTING
4.1. If there is no voltage reading, check the MCOR. See Test Procedure 4 – MCOR Voltage on
page 11-17. Also check the continuity of the large posts of the solenoid. See Test Procedure 14
– Solenoid Continuity on page 11-35.
4.2. Disconnect the battery cables as instructed. See WARNING "To avoid unintentionally start-
ing..." in General Warnings, Section 1, Page 1-1.
4.3. Check continuity on A1 and A2 motor terminal posts and continuity of the F1 and F2 motor terminal
posts. Also, check continuity of all motor wires. See Section 15a – Motor (Model
5BC59JBS6365).
TEST PROCEDURE 6 – TOW/RUN SWITCH
See General Warnings, Section 1, Page 1-1.
Tow/Run Switch Test with the IQDM Handset
1. With the Tow/Run switch in the RUN position, connect the IQDM to the vehicle as described in the IQDM
Owner's Manual.
2. Immediately after the IQDM is connected to the vehicle, the screen should display a copyright notice and
the IQDM model number.
3. If the IQDM display screen is blank, drive the vehicle a short distance to activate the onboard computer.
4. If the IQDM display screen begins to work after the vehicle has been driven, turn the key switch to the
OFF position and proceed to step 5; otherwise, perform the following procedure, Tow/Run Switch Test
without the IQDM Handset.
5. With the IQDM still connected to the vehicle, place the Tow/Run Switch in the TOW position and wait 90
seconds.
6. If the IQDM display screen goes blank after 90 seconds, the Tow/Run switch and connecting wires are
operating correctly.
7. If the IQDM display screen is still active after 90 seconds, the switch has failed closed. Replace the Tow/
Run switch. See Tow/Run Switch Removal, Section 12, Page 12-6.
Tow/Run Switch Test without the IQDM Handset
1. With the batteries connected and using a multimeter set on 200 volts DC, connect the black (–) probe to
the negative post of battery no. 4 and connect red (+) probe (with insulation-piercing probe) on the pink
wire close to the connector on the Tow/Run switch.

WARNING
• The key switch should be placed in the OFF position and left in the OFF position for the
duration of this test.
2. With the Tow/Run switch in the RUN position, the reading should be approximately 48-50 volts. With the
switch in the TOW position, the reading should be below approximately 5 volts.
3. If the reading is above 5 volts with the switch in the TOW position, replace the switch.
4. If the reading is below 5 volts with switch in the RUN position, check continuity of the blue 18-gauge wire
from the large post of the solenoid to the connector at the Tow/Run switch.
5. If the continuity readings are correct, replace the Tow/Run switch.
