CHECK CONNECTION OF CONNECTORS |
(a) Turn the ignition switch off.
(b) Disconnect the cable from the negative (-) battery terminal.
CAUTION:
Wait at least 60 seconds after disconnecting the cable from the negative (-) battery terminal to disable the SRS system.
(c) Check that the connectors are properly connected to the horn button assembly, spiral cable sub-assembly and airbag ECU assembly.
OK:
The connectors are properly connected.

3. |
CHECK CONNECTORS |
(a) Disconnect the connectors from the horn button assembly, spiral cable sub-assembly and airbag ECU assembly.
(b) Check that the terminals of the connectors are not deformed or damaged. OK: The terminals of the connectors are not deformed or damaged. |
|
(c) Check that the short springs of the activation prevention mechanisms of the wire harness connector and spiral cable sub-assembly connector are not deformed or damaged.
OK:
The short springs are not deformed or damaged.
(d) Check that the spiral cable sub-assembly connector (on the horn button assembly side) is not loose, deformed or damaged.
OK:
The airbag connector locking button is not disengaged, and the claw of the lock is not deformed or damaged.

4. |
CLEAR DTC |
(a) Connect the connectors to the airbag ECU assembly and spiral cable sub-assembly. |
|
(b) Connect the white wire side of SST (resistance 2.1 Ω) to connector E (black connector).
CAUTION:
Never connect a tester to the horn button assembly for measurement, as this may lead to a serious injury due to airbag deployment.
