STEP 4. Voltage measurement at the SRS-ECU connector.
(1) Check that the negative battery terminal is disconnected. If the negative battery terminal is connected, disconnect it.
(2) 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, and disconnect the SRS-ECU connector.
(3) danger | To release the connector short spring in the following operations, disconnect this side-airbag module connector, and keep the squib circuit shorted. |
Disconnect the side-airbag module (RH) connector, unlock the connector by sliding the locking button to the direction of the arrow as shown in the figure, and then disconnect the connector. (4) caution | The short spring may not be released due to the insufficient insertion, thus insert for 4 mm (0.16 inch) or more. |
Insert a cable tie [3 mm (0.12 inch) wide, 0.5 mm (0.02 inch) thick] between the SRS+, SRS- line and the short spring, and then release the short spring.
(5) Connect the negative battery terminal.
(6) Electric motor switch: ON
(7) Take the measurements below at the SRS-ECU harness side connector.- Voltage between SRS+, SRS- line and body ground
OK: 1 V or less
(8) Disconnect the negative battery terminal.
Is the check result normal?
Go to Step 5. Repair the wiring harness SRS+, SRS- line between the SRS-ECU connector and the side-airbag module (RH) connector.
