Code No.B2546 LH side view CAMERA fault
 
 
 
 
TROUBLE JUDGEMENT
If signal from the side-view camera (LH) cannot be received for 5 seconds or more, the camera-ECU sets diagnosis code No.B2546.
noteWhen diagnosis code No.B2546 is set, the segment, which corresponds to a defective camera, is displayed in blue.
 
 
PROBABLE CAUSES
  • Malfunction of door mirror assembly (LH)
  • Malfunction of camera-ECU
  • Damaged harness wires and connectors
 
 
DIAGNOSIS PROCEDURE
STEP 1. Check the wiring harness between side-view camera (LH) connector and camera-ECU connector.
Check the following.
  • Check of open circuit in ACCS line.
  • Check of open circuit in GNDS line.
  • Check of open or short circuit in VSV line.
  • Check of open circuit in S-EX line.
Is the check result normal?
Go to Step 2.
Repair the connector(s) or wiring harness.
 
STEP 2. Check whether the diagnosis code is set again.
Check again if the diagnosis code is set in the camera-ECU.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from the "LOCK" (OFF) position to the "ON" position.
(3) Check if diagnosis code is set.
Is the diagnosis code set?
Go to Step 3.
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
 
STEP 3. Check the side-view camera (LH).
Use an oscilloscope to check the output waveform of the side-view camera (LH) (Refer to ).
Is the check result normal?
Go to Step 4.
Replace the side-view camera (LH) (Refer to ).
 
STEP 4. Check whether the diagnosis code is set again.
Check again if the diagnosis code is set in the camera-ECU.
(1) Erase the diagnosis code.
(2) Turn the ignition switch from the "LOCK" (OFF) position to the "ON" position.
(3) Check if diagnosis code is set.
Is the diagnosis code set?
Replace the camera-ECU (Refer to ).
