Services Performed
- Performed battery test using Midtronics tester, found battery tests good at 795A EN with battery capacity of 850A EN. Connected ammeter to vehicle to vehicle to check for potential quiescent current draw with vehicle off and vehicle's CAN network in dormant state, found vehicle does not go below 330mA, vehicle should not go above 50-60mA. Accessed SAM modules to perform electrical draw testing, found when fuse 58 pulled from rear SAM module that draw goes down to approx 30-35mA, determined fuse 58 is for keyless go module. Re-installed fuse 58 and accessed keyless go module, removed connectors from module individually to ensure no circuits coming from module potentially causing draw, was able to isolate current draw when vehicle off to actual keyless go module, recommend replacing
- Replace keyless go module and re-program/initialize keys to vehicle for keyless go///USED KEYLESS GO MODULE
