ELECTRICALS 199 9.0 DIAGNOSTIC TROUBLE CODES FOR ENGINE MANAGEMENT SYSTEM:- Sr. No. Displayed DTC Code DTC Description Fault cause Probable trouble Area 1 U0001 - 8 High speed CAN communication bus - bus ‘OFF’. Bus ‘OFF’ 1) Check loose connections. 2) Check connection between main and ESS ECU. 2 U0001 - 3 High speed CAN communication bus performance - circuit open. Circuit open 1) Check loose connections. 2) Check connection between main and ESS ECU. 3 P0641 - C Output voltage of the sensor supply 1 is out of its specified range - circuit voltage out of range. Circuit voltage out of range To be updated. 4 P0697 - C Output voltage of the sensor supply 3 is out of its specified range - circuit voltage out of range. Circuit voltage out of range To be updated. 5 P2135 - 29 Throttle position sensor "A" and "B", signal not plausible or both throttle position sensors of DV−E haven´t passed test. Signal invalid 1) Loose/ Damaged connections or intermittent fault. 2) Sensor supply line short circuit to battery/ ground. 3) Sensor signal line short circuit to battery/ ground. 4) Check the continuity from sensor connector pins to the ECU pins. 5) Check for back out of pins at both sensor connector and ECU connector. 6) Check for damage of pins at both sensor connector and ECU connector. 7) Faulty ECU. 6 P0123 - 12 Throttle/pedal position sensor/switch "A" circuit high. Circuit short to battery 1) Loose/ damaged connections or intermittent fault. 2) Sensor supply line short circuit to battery/ ground. 3) Sensor signal line short circuit to battery/ sensor supply/ ground. 4) Check the continuity from sensor connector pins to the ECU pins. 5) Check for back out of pins at both sensor connector and ECU connector. 6) Check for damage of pins at both sensor connector and ECU connector. 7) Faulty throttle position sensor. 8) Faulty ECU.
