Fixes & Summaries for GM

| 2012 Chevrolet Colorado LT 3.7L Odometer VIN: 1GCDSCFE5C Thanks for the help. The right answer was to send both the bcm and ipc out and have them reset. There is no way to set mileage on the replacement bcm. This was a used truck from an auction so who knows what was done in the past. |

| 2015 GMC Terrain SLE 2.4L Negative Fuel Trims VIN: 2GKALMEK9F I swapped the high-pressure fuel pump off my personal 2012 Terrain. Replacing the fuel pump resolved the issue. STFT is now +- 2 and LTFT is -2. A far cry from the -40 before. Trouble codes: P0138 (HO2S Delayed Response Rich to Lean Sensor 2. Test Failed), P013E, P0140 (HO2S Circuit Insufficient Activity Sensor 2 Sympton 00 Test Failed Warning Indicator Requested). |
