C-36 SRS-ECU connector.
(4) Measure the resistance between terminal 55, 58 and body
ground (No. B1B54 only).
It should be an open circuit.
(5) Measure the voltage between terminal 55, 58 and body
ground (No. B1B55 only).
Voltage should measure 0 voltage.
Q: Is the check result normal?
YES : Go to Step 5.
NO : Go to Step 4.
STEP 4. Check the harness wires between SRS-ECU
connector C-36 (terminal No.55 and 58) and the seat belt
buckle switch (passenger’s side) connector D-37 (terminal
No.1 and 2) (No. B1B56 only).
Q: Are harness wires between SRS-ECU connector C-36
(terminal No.55 and 58) and the seat belt buckle switch
(passenger’s side) connector D-37 (terminal No.1 and 2)
in good condition?
YES : Go to Step 6.
NO : Repair the harness wires between SRS-ECU
connector C-36 and the seat belt buckle switch
