EH6 Checking Wiring Harness (Circuit 839)

^ In order to determine if vehicle wiring harness has the soft shock relay circuits in proper location the following test is required:

^ Using an analog ohmmeter, connect one lead to soft shock relay vehicle wiring harness connector Circuit 839 and other to a known good chassis ground.

^ Is ohmmeter reading less than 2 ohms?

YES -- Soft shock relay power Circuit 830 and ground Circuit 4305 are reversed. RELOCATE these circuits to the proper location. RECONNECT soft shock relay and air suspension control module. REPEAT Service Bay Diagnostics. Reading and Clearing Diagnostic Trouble Codes

NO -- Go to EH7.
