6.2. Set a multimeter to 200 volts DC. Place the black (–) probe on the battery no. 6 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 Warning, Section 10, Page 10-1.
NOTE: Be aware that one of two different solenoids may be found on the vehicle. Visually, the production
solenoid is smaller than the service replacement. On the labels, the larger service replacement
solenoid has SOL0605 and the smaller production solenoid has SOL5006. Internally, specifica-
tions and test results differ between the two.
1. Disconnect the batteries and discharge the controller. See Disconnecting The Batteries on page 10-3.
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.
- Factory-installed solenoids: A reading of 200 to 250 ohms should be obtained (Figure 11-12,
Page 11-19) . If not, replace the solenoid.
- Service replacement solenoids: A reading of 180 to 190 ohms should be obtained (Figure 11-13,
Page 11-19) . If not, replace the solenoid.
TEST PROCEDURE 4 – MCOR VOLTAGE
See General Warning, Section 10, Page 10-1.
The accelerator position, which is proportional to the MCOR voltage, can be displayed with the IQDM hand-
set. If an IQDM handset is not available, proceed to MCOR Voltage Test without the IQDM Handset on
page 11-20.
MCOR Voltage 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, Section 10, Page 10-2.
