the high resistance condition due to terminal fretting corrosion.

Observe the scan tool Deployment Loop Resistance parameters while moving the harness near each connector listed below. The reading should stay

consistently between 1.7 and 4.2 ohm without any drop outs or spikes.

If the reading is erratic while moving the harness, perform the following:

* Inspect each connector terminal for damage or corrosion and repair as necessary.

* Apply Nyogel lubricant 760G to each connector terminal.

* Insure each connector and CPA is correctly seated.
