G sensor short circuit or broken circuit 1. Firstly disconnect the connector at harness side, and connect the harness sensor battery anode with the No. 15 pin of short cathode, and then perform ground connection. Finally measure the malfunction voltage of No. 13 pin short circuit or broken circuit as well as the voltage of No. 15 pin (normal voltage scope is between 0.6 ~ 4.5V). 2. Sensor voltage less than 2v indicates sensor broken circuit or ground wire short circuit or sensor connecting piece plug disengagement. 3. Confirm whether there is supply power (IGN1) for G sensor (normal voltage scope shall be between 10 - 16V). 4. If there is no problem occurs to item 1, 2 and 3, but there still exist errors, it can be confirmed as ECU internal circuit troubles. The anode or cathode of sensor has short circuit / broken circuit over the ground
