System Test

With ignition off, disconnect Transmission Control Module (TCM). See Fig 1 . Disconnect 2-pin and 3-pin connectors at Speed Proportional Steering Module (SPSM). See Fig 2 . Inspect connectors and clean or repair if necessary.

Using an ohmmeter, probe ground circuit. See Fig 4 . If resistance is greater than 5 ohms, repair open ground circuit and perform TEST VER-1 . If resistance is less than 5 ohms, go to next step.
With ignition on, use a voltmeter to probe the fused ignition switch output circuit (pins No. 8 and 11). See Fig 4 . If the voltage is less than 9 volts, repair open fused ignition switch output circuit and perform TEST VER-1 . If voltage is greater than 9 volts, go to next step.
Using an ohmmeter, measure across solenoid control valve circuit 2 pin connector. See Fig 2 . If resistance is 5-7 ohms, replace speed proportional steering module and perform TEST VER-1 . If resistance is not 5-7 ohms, replace solenoid control valve and pigtail. Perform TEST VER-1 .
