W/Harness Inspection

Engine Control
U0164 CAN Communication BUS with FATC(Timeout) - Inspection/Repair:_:W/Harness Inspection

Terminal and Connection Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?






CAN communication circuit inspection

Check open in CAN BUS line
1. IG "OFF" and disconnect A/C Control module connector and ECM connector.
2. Check resistance between CAN-HIGH terminal of A/C Control module Connector and CAN-HIGH terminal of harness connector.(Measurement "A")
3. Check resistance between CAN-LOW terminal of A/C Control module Connector and CAN-LOW terminal of harness connector.(Measurement "B")

Specification :Below 1.0Ohms




4. Is the measured resistance within specification?
