DTC P0401 EGR FUNCTION
CONSULT-II Reference Value in Data Monitor Mode
EBS013DI
Specification data are reference values.
ECM Terminals and Reference Value
EBS013DJ
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
