What This Code Means
Electric failure in the stop lamp power stage; Electric failure in the warning lamp power stage; Injector will not be corrected; 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
- •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
- •EEPROM checksums are incorrect
- •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
- •Command collision
- •RAM error
- •Short circuit
Suggested Actions
- 1Perform injector correction at the end of the production line (EOL) or after injector substitution using a tester
