2 Check the harness between the ground controls and the faulted device
1 Disconnect the GCON ECM connectors, J1, J2 and J3.
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.
