Measure the resistance between terminal 3 and terminal 4.
It should be an open circuit
Q:Does the resistance meet the value above?
YES:
Erase the diagnostic trouble code memory, and check
the diagnostic trouble code. If DTC B1B50, B1B51or B1B52
are set, replace the SRS-ECU. (Refer to P.52B-326.) Then
go to Step 6.
NO:
Go to Step 5.
STEP 5. Check the harness wires between SRS-ECU
connector C-27 (terminal No.56 and 57) and driver’s seat
belt switch connector D-28 (terminal No.3 and 4).
Q:Are harness wires between SRS-ECU connector C-27
(terminal No.56 and 57) and driver’s seat belt switch
connector D-28 (terminal No.3 and 4) in good condition?
YES:
Go to Step 6.
NO:
Replace the harness wires between SRS-ECU connector
C-27 and driver’s seat belt switch connector D-28. Then
go to Step 6.
STEP 6. Recheck for diagnostic trouble code.
