STEP 3. Check the harness short circuit between seat belt switch (driver’s side) connector D-33 and the SRS-ECU connector C-124, C-125.
(1) Disconnect the negative battery terminal.
(2) Disconnect the seat belt switch (driver’s side) connector D-33.
(3) While pushing the part "A" indicated in the figure of the harness side connector, turn the lock lever to the direction of the arrow to release the lock lever. After disconnecting the C-124, C-125 SRS-ECU connector, connect it again.
(4) Measure the resistance between terminal 43, 63 and body ground (No. B1527 only).It should be an open circuit.
(5) Connect the negative battery terminal.
(6) Ignition switch: ON.
(7) Measure the voltage between terminal 43, 63 and body ground (No. B1528 only).Voltage should measure 1 volt or less.
Is the check result normal?
Go to Step 5. Go to Step 4.
