ELECTRICAL SYSTEM AND TESTING
Test Procedure 2 – Onboard Computer Solenoid Lockout Circuit, Continued:
6. If the dash light does not illuminate and the vehicle does not operate, check the OBC activation circuit.
6.1. Using a multimeter set to 200 volts DC, place the black (–) probe on the battery no. 4 negative post
and place the red (+) probe (with insulation-piercing probe) on the red 18-gauge wire located on the
OBC side of the six-pin connector. The reading should be approximately 48 volts. If the reading is
incorrect, test the Tow/Run switch and connecting wires. See Test Procedure 6 – Tow/Run Switch
on page 11-19.
6.2. Using a multimeter set to 200 volts DC, place the black (–) probe on the battery no. 4 negative post
and place the red (+) probe (with insulation-piercing probe) on the red 18-gauge wire (harness side
of six-pin connector). Multimeter should indicate 48 volts. If voltage is correct, check connections
in the six-pin connector. If connections are correct, OBC activation circuit has failed. Replace OBC.
TEST PROCEDURE 3 – SOLENOID ACTIVATING COIL
See General Warnings, Section 1, Page 1-1.
1. Disconnect the battery cables as instructed. See WARNING "To avoid unintentionally starting..." in
General Warnings, Section 1, Page 1-1.
2. Remove the two small wire terminals from the solenoid.
3. Place red (+) probe of the multimeter on the positive (+) solenoid terminal. Place the black (–) probe on
the other small solenoid terminal. A reading of 180 to 190 ohms should be obtained (Figure 11-8,
Page 11-16). If not, replace the solenoid.
