Step 30

Step 32

Connect the positive (+) test lead to the relay terminal (tan/red wire) of the park brake switch. With the key switch and park brake switch in the ON position, the multimeter should read 12 to 13 volts.

If there is no voltage, replace the park brake switch.

If there is 12 to 13 volts, but no voltage at Step 24, replace the tan/red wire between the switch and the relay.

Step 31

Move the park brake switch to the OFF position. The multimeter should read 0 volts.

If there is no voltage, but there was 12 to 13 volts at Step 25 replace the lift cylinder proximity switch.

If there is 12 to 13 volts, replace the park brake switch.

Stabilizer Cylinder Solenoid Valve Tests

STEP 33

Check the park brake/stabilizer cylinder fuse (#2) (1) and, test the power to the fuse (Step 4) and ignition relay (2) (Steps 5 and 6).

STEP 34

Check the power to the park brake relay (#2). Complete Steps 23, 24 and 25.

Step 35

Disconnect

Install the positive (+) test lead in the red/white wire prong of the wire harness connector. Install the negative (-) test lead in the black wire prong. Turn the key switch to the ON position. With the park brake switch in the OFF position the multimeter should read 12 to 13 volts.

If there is no voltage, repair or replace the wire between the park brake/stabilizer cylinder relay (E3) and the cylinder.

If there is 12 to 13 volts, but the stabilizer cylinder restricts the frame leveling movement, replace the stablizer cylinder solenoid valve.
