Check the device associated with the faulted circuit
1 Disconnect the faulted device connector.
2 Using a multi-meter, measure resistance between the two
terminals of the faulted device.
3 Resistance should be as follows.
Device
Solenoid Valve, Drive
Solenoid Valve, Steer
Solenoid Valve, Platform Up

1 Disconnect the GCON ECM connectors, C1, C2 and C3.
(or C4 if equipped with outriggers).
2 Disconnect the faulted device connector.
3 Check the continuity between the GCON ECM connector
and the signal side of the faulted device.
 Result: Resistance should be close to 0 Ω.
4 Check the continuity between the return side of faulted
device and system ground.
 Result: Resistance should be close to 0 Ω.
5 Check resistance between return side and signal side of
the harness plug of faulted device.
 Result: Resistance should be 1M Ω or higher.
