163 Trouble shooting for electrical faults to be done in the following order only On the fault discription High Fault referes to Shortcircuit to Vbat or 12V On the fault discription Low Fault referes to Shortcircuit to Ground or Chassis Ground Confirm the fault Read Fault Code Short circuit fault present Check loose connection Identify pins on ECU and sensor side Terminal backout on connectors. Check Continuity between the pins. Check for any O/C Check Sensor Condition Breakage / Malfunction Faults appear in groups of 5 or more (not necessarily from individual sensors) Check wiring of all the sensors (in the fault group) for contact with chassis ground or Vbatt Connect properly Rectify wiring Change sensor Yes Yes Yes Yes No (Will be an Open Circuit Fault) No No Identify corresponding sensor TROUBLESHOOTINGFLOWCHART List of Short Circuit faults S.No DTC Fault Variable Sensor 1 P0102 F_M_AMF_SENSOR_APV AMF sensor 2 P0237 F_M_BOOST_PRES_APV Boost Pressure sensor 3 P0253 F_M_IMV_DRIVE_APV IMVSensor 4 P0117 F_M_COOLANT_SENSOR_APV Coolant temperature sensor 5 P0182 F_M_FUEL_TEMP_APV Fuel temperature sensor 6 P0192 F_M_RAIL_PRES_APV Rail Pressure sensor 7 P0122 F_M_PEDAL_TRACK1_APV Pedal sensor Track1 8 P0222 F_M_PEDAL_TRACK2_APV Pedal sensor Track2 9 P2147 F_M_FCI_DRIVE_APV_0 Injector Bank1 10 P2150 F_M_FCI_DRIVE_APV_1 Injector Bank2 11 P0245 F_M_VGT_VALVE_DRIVE_APV EVRVforVGT 12 P0489 F_M_EGR_VALVE_DRIVE_APV EVRVforEGR DTC (DIAGNOSTICTROUBLECODES) LIST
