Sensor Supply Voltage 2
â–¶ How to fix
Erase fault memory and check if fault is still present. If fault is still present exchange the ECU to fix the problem.
What you'll see
No driver-visible symptom recorded.
System reaction
System pressure is calculated only out of pressure in circuit 21. No influence on basic functionality. Limiter failure in circuit 26 can not be detected.
Diagnostic depth
Detection
Voltage measurement indicates a LIN sensor supply undervoltage at the sensors 22 & 26.
Possible cause
Internal hardware failure.
