11.17.8.1 CAN Bus Network Integrity Checking

1. Turn off the ignition switch, use a multimeter to measure
the datalink connector terminals PIN6 and PIN14
resistance.
2. If the multimeter shows about 110-125 Ω resistance or
non-conduction, the CAN bus is incomplete.
3. Check the ECM and the BCM harness connectors,
confirm the CAN bus connection is normal. If there are
undesirable situations such as open circuit or connection,
carry out repairs.
Note
CAN bus repairs must follow the repair specification.
Refer to 11.17.7.5 CAN Bus Wiring Harness Repair
Specification.
FE11-1419b
4. If the multimeter shows that the resistance is about 55-63
Ω, it means the from the BCM to ECM the CAN bus is
complete.
