What This Code Means

Stop Lamp power stage electric failure; Warning Lamp power stage electric failure; Injector will not be corrected; Fault code stored in EEPROM; Incorrect engine angle and speed determination; Poor speed sensor signal quality; Speed sensor signal plausibility failure; Loss of torque/speed demand signal transmission from Vehicle Controller to EDC; Triggering of substitute reaction in diagnostic system; Injector hardware failure detected; ECM power stage failure detected; Electric failure in the stop lamp power stage; Electric failure in the warning lamp power stage; Incorrect engine speed and angle determination; Loss of signal plausibility and quality between camshaft and crankshaft sensors; Active timeout of TSC1 CAN messages (torque/speed request is active); Passive timeout of TSC1 CAN messages (no torque/speed request is active); Hardware error in injector; Hardware error in ECM power stage; Measured and reference behavior patterns match (error bit mask detected)

Possible Causes

  • Electric failures in the power stage of the Stop Lamp detected by hardware monitoring
  • Electric failures in the power stage of the Warning Lamp detected by hardware monitoring
  • Injector correction values read from the EEPROM are not plausible
  • EEPROM checksums are incorrect
  • Plausibility issues between camshaft and crankshaft speed sensor signals
  • Active timeout (TSC1 CAN messages not sent at fast rate when request is active)
  • Passive timeout (TSC1 CAN messages not sent at slow rate when no request is active)
  • Overcurrent in the injectors or ECM power stages
  • Command collision
  • RAM error
  • Short circuit
  • Measured pattern matches the reference pattern of expected combination of errors
  • Hardware monitored electric failure in the Stop Lamp power stage
  • Hardware monitored electric failure in the Warning Lamp power stage
  • EEPROM injector correction data is not plausible
  • Camshaft and crankshaft speed sensor signals are not plausible
  • Timeout of TSC1 messages containing torque/speed demand information from the Vehicle Controller to the EDC
  • Overcurrent

Suggested Actions

  1. 1Correct injector values at the end of production line (EOL)
  2. 2Perform injector correction with the tester after substitution of the injectors
  3. 3Perform injector correction at the end of the production line (EOL) or after injector substitution using a tester
