Volvo All Engines (2013 Emissions) Fault Code: P06B100 PID: ACM Sensor Power Supply “A” Circuit Low

The control module provides the following sensors with 5V supply voltage
B115: Aftertreatment DPF Differential Pressure Sensor
If an abnormal voltage or current is detected on the common supply a DTC is set

Conditions for diagnostic trouble code (DTC):
1) The voltage at pin A137:50 is less than 4.5?V

Observable symptoms
1) None

Probable cause
1) Wiring harness
2) Connector
3) B115: Aftertreatment DPF Differential Pressure Sensor
4) A137: Aftertreatment Control Module (ACM)
