Condition / Concern
IPC cluster/radio/HVAC display blanks out, Bluetooth phone or Pandora connection dropped, the radio station or volume changes when operating the snow plow.
A snow plow places very high electrical loads on a truck’s charging system when it is being operated (during plow movement). It demands the highest load (as high as 200 amps) when it is raised up completely or turned to either left or right maximum angle. As this load is turned on and off, the truck’s charging system has to react within a faction of a second to either increase or decrease its output to meet the plow’s requirements.
There is no way for the truck’s charging system to know when the driver is going to operate the snow plow, and in some cases, when the load is suddenly turned off, the charging system may momentarily over-charge for a fraction of a second. If this happens it can cause the various complaints listed above.
Recommendations / Instructions
To correct this condition install the snow plow generator jumper harness.
For 2019 (new body style) to 2022 trucks, please reference the latest version of GM Upfitter Integration Bulletin 161 for additional information and installation instructions.
For 2014 to 2019 (old body style) trucks, please reference the latest version of GM Upfitter Integration Bulletin 124 for additional information and installation instructions.
