THIS PRELIMINARY INFORMATION COMMUNICATION ADVISES THE TECHNICIAN THAT ,WHEN TESTING ANY CIRCUIT FOR OPEN OR RESISTANCE, IT IS IMPERATIVE THAT ALL RELATED TERMINAL PIN FIT AND TENSION BE CHECKED WHEN THE TEST STEPS REQUIRE DISCONNECTION OF THE CONNECTOR OR COMPONENT, PRIOR TO ANY COMPONENT REPLACEMENT. ALWAYS USE THE RECOMMENDED TERMINAL TEST TOOL DURING THESE TESTS.

THIS PRELIMINARY INFORMATION COMMUNICATION PROVIDES INFORMATION TO THE TECHNICIAN ON THE STEPS TO DIAGNOSE AND REPAIR VEHICLES THAT MAY HAVE AN INTERMITTENT "CHECK TRAILER WIRING" OR "SERVICE TRAILER BRAKE" MESSAGE ON THE DRIVER INFORMATION CENTER. TECHNICIAN WILL INSPECT AND CLEAN THE GROUND WIRE (NORMALLY WHITE WIRE) CONNECTION ON THE TRAILER SIDE OF THE 7-PIN CONNECTOR. INSPECT THAT THE WIRES INSIDE THE TRAILER SIDE CONNECTOR ARE CLEAN AND SECURELY FASTENED. IF THE VEHICLES 7-WAY CONNECTOR SOCKET TERMINALS ARE DEFORMED OR HAVE EXCESSIVE WEAR, IT WILL BE NECESSARY TO REPLACE THE TRUCK SIDE CONNECTOR FROM GENERAL MOTORS CUSTOMER CARE AND AFTERSALES ALONG WITH THE TRAILER'S 7-WAY CONNECTOR PLUG.

THIS PRELIMINARY INFORMATION COMMUNICATION PROVIDES INFORMATION TO THE TECHNICIAN THE STEPS NEEDED TO DIAGNOSE AND REPAIR VEHICLES WITH A ROUGH IDLE AND/OR VIBRATION AT IDLE IN DRIVE. THIS CONDITION WILL NOT BE PRESENT IN PARK, OR NEUTRAL. THIS CONCERN MAY BE CAUSED BY GROUND OUT WITHIN THE ONE OR BOTH ENGINE MOUNTS. TECHNICIAN WILL USE CH-51450-A (PICO OSCILLOSCOPE) TO MEASURE THE VIBRATION DISTURBANCE. IF THE VIBRATION CONCERN IS E1.5 IN THE HORIZONTAL / LATERAL DIRECTION WITH PICO SENSOR MOUNTED IN SEAT TRACK AS INDICATED CONTINUE WITH STEPS TO REDUCE THE AMPLITUDE OF THE VIBRATION BY ADDING SPACERS IN KEY LOCATIONS TO REDUCE GROUND OUT WITHIN THE ENGINE MOUNTS. THE 6.2L ENGINE HAS A CHARACTERISTIC E1 WHICH CAN BE FELT, AND MAY BE DESCRIBED AS A LOPEY IDLE. DO NOT CONFUSE 6.2L E1 CHARACTERISTIC (NOT CAUSED BY MOUNT GROUND-OUT), WITH E1.5 NORMAL IDLE CHARACTERISTICS BEING TRANSMITTED INTO THE TRUCK VIA GROUND-OUT THRU THE ENGINE MOUNTS. IF MEASURING HIGH AT THE SEAT TRACK 12 MG OR GREATER; REPLACEMENT OF THE ENGINE MOUNTS SHOULD HELP REDUCE THE AMPLITUDE OF THE VIBRATION. IF THE DISTURBANCE MEASURES AT THE SEAT TRACK AS E1.5 LATERAL IN THE RANGE OF APPROXIMATELY 2.5 - 8 MG USING A TRI-AXIS SENSOR. THEN PLACE TRI-AXIS PICO SENSOR ON THE INBOARD SEAT TRACK FORWARD-MOST LOCATION TO RECORD MEASUREMENT OF THE ROUGH IDLE VIBRATION CONCERN. WITH THE HEATER-VENT-AIR CONDITIONING ON PERFORM SEVERAL SHORT HEAVY LAUNCH EVENTS FROM STOP TO STOP TO BRING THE TEMPERATURES BACK UP WHILE ATTEMPTING TO RE-CREATE THE ROUGH IDLE VIBRATION IN DRIVE WITH PICO SENSOR PLACED ON INBOARD SEAT TRACK; WHILE THE VIBRATION IS ACTIVE RECORD PICO READING. THIS METHOD SEEMS TO PROVIDE BETTER RESULTS THAN EXTENDED TEST DRIVES. IF THE PICO READING FOR E1.5, WITH VIBRATION ACTIVE, AT SPECIFIED SEAT TRACK LOCATION MEASURES CLOSE TO 2MG OR LESS USE SERVICE INFORMATION TO DIAGNOSE ROUGH IDLE / VIBRATION.
