STEP 3. Diagnosis check by dummy resistor connection.
(1) Check that the negative battery terminal is disconnected. If the negative battery terminal is connected, disconnect it.
(2) Disconnect the side-airbag module (LH) 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.
(3) Connect special tool dummy resistor (MB991865) to special tool resistor harness (MB991866).
(4) caution | Do not insert a probe directly into the terminal from the connector front side as the connector contact pressure may be weakened. |
Insert the resistor harness probe from the back of side-airbag module (LH) harness side connector.
(5) Connect the negative battery terminal.
(6) After erasing the DTC memory, check the DTC again.
(7) Disconnect the negative battery terminal.
Is the DTC B1433 stored?
