1.
Mount the tester on the multimeter. Make sure the pins are positioned correctly ac-
cording to the colour markings. Red pin to V/Ohm on the multimeter. Set the multi-
meter measuring range to ohms.
2.
Connect the tester's 5-pin connectors to the CAN network requiring measurement:
Decoder: contact X3 or X4.
Display, application and master modules: connector X2, X3 or X4.
I/O modules: contact X1 or X19.
Resolver modules: contact X3 or X4.
3.
Select CABLE TEST on the CAN tester. The multimeter should read about 60-65
Ohms if the cable is intact.
Fault indication
n If the multimeter reads 120 Ohm, the end plug is missing or there is a break in a cable.
!
NOTE: Because of the internal resistance in the tester, the multimeter reads about 100
kOhm if the cables are not connected or if there is an open circuit in one of the cables.
