VERIFY FRONT BODY CONTROL MODULE (FBCM) DTCs AGAIN
• Clear the DTC for the front body control module (FBCM) using the M-MDS.
• Switch the ignition ON (engine off or on) and wait for 1 s or more.
• Retrieve the front body control module (FBCM) DTCs using the M-MDS.
• Is the same DTC displayed?
|
Yes
|
LIN communication line can be considered the cause.
• Refer to the wiring diagram and verify whether or not there is a common connector between following terminals:
-
― Auto light sensor/rain sensor terminal A—Front body control module (FBCM) terminal 2G (With auto light sensor/rain sensor)
― Climate control unit terminal K—Front body control module (FBCM) terminal 2J (With manual A/C)
If there is a common connector:
-
• Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a malfunction.
• Repair or replace the malfunctioning part.
If there is no common connector:
-
• Repair or replace the wiring harness.
• Go to the next step.
