Disconnect P1 connector from the WEDGE, J02
connector from the engine ECM, P100 from the Auto

connected to the J1939 CAN BUSS network. Using
a multimeter, measure the resistance between P100-

should be 60 ohms across
P100-20 and P100-23
If not, measure resistance
value of each terminator (120
ohms) and or check for
defective splice, broken
WJDe, and loose connection
at connector pins
