COMMON RAIL SYSTEM V3800-CR-TE4,V3800-CR-TIE4, DM 1. Measure the ECU +BP and Ground Voltage 1. Turn the key switch ON and measure the voltage between the ECU +BP terminals (B-5 / B-6) and ground (body / battery terminal). Then measure voltage between the ECU ground terminals (B-3 / B-4) and ground (body / battery terminal).
