Preliminary Check:
1.
Check resistance in Diagnostic CAN pin no. 6 and 14. It should be 120ohm.
2.
Check for short conditions between CAN_H-CAN_L, CAN_H-GND, CAN_L-GND, CAN_H-Vbatt and CAN_L-
GND. There should not be any short circuit conditions.
3.
Check continuity between IPC CAN_H (pin no. 15) vehicle side connector to OBD connector CAN_H (pin no. 6)
and CAN_L (pin no. 14) vehicle side connector to ODB connector (pin no.14).
ϰ͘
