PROCEDURE
1. | CHECK CURRENT DTC |
(a) Turn the ignition switch to ON, and wait for at least 60 seconds.
(b) Check for DTCs.
Body Electrical > SRS Airbag > Trouble Codes Result | Proceed to |
---|---|
Current B000111 is output | A |
History B000111 is output | B |
B | USE SIMULATION METHOD TO CHECK |
|
2. | CHECK CONNECTION OF CONNECTORS |
(a) Turn the ignition switch off.
(b) Disconnect the cable from the negative (-) auxiliary battery terminal.
CAUTION:
Wait at least 60 seconds after disconnecting the cable from the negative (-) auxiliary 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 sensor assembly.
OK:
The connectors are properly connected.
NG | CONNECT CONNECTORS PROPERLY |
|
3. | CHECK CONNECTORS |
(a) Disconnect the connectors from the horn button assembly, spiral cable sub-assembly and airbag sensor 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.
NG | REPLACE SPIRAL CABLE SUB-ASSEMBLY OR REPAIR OR REPLACE WIRE HARNESS |
|
4. | CHECK HORN BUTTON ASSEMBLY |
(a) Connect the connectors to the airbag sensor assembly and spiral cable sub-assembly. |
|
(b) Connect the white wire side of SST (resistance 2.1 Ω) to connector E (light green 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.
NOTICE:
SST: 09843-18061
(c) Connect the cable to the negative (-) auxiliary battery terminal.
(d) Turn the ignition switch to ON, and wait for at least 60 seconds.
(e) Clear the DTCs stored in memory.
Body Electrical > SRS Airbag > Clear DTCs(f) Turn the ignition switch off.

5. | CHECK HORN BUTTON ASSEMBLY |
(a) Turn the ignition switch to ON, and wait for at least 60 seconds.
(b) Check for DTCs.
Body Electrical > SRS Airbag > Trouble CodesHINT:
Codes other than DTC B000111 may be output at this time, but they are not related to this check.

B000111 is output | B |
(c) Turn the ignition switch off.
(d) Disconnect the cable from the negative (-) auxiliary battery terminal.
CAUTION:
Wait at least 60 seconds after disconnecting the cable from the negative (-) auxiliary battery terminal to disable the SRS system.
(e) Disconnect SST from connector E.
A | REPLACE HORN BUTTON ASSEMBLY |
|
6. | CHECK DRIVER SEAT AIRBAG SQUIB CIRCUIT |
(a) Disconnect the connector from the airbag sensor assembly. |
|
(b) Check for a short to ground in the circuit.
(1) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
Tester Connection | Condition | Specified Condition |
---|---|---|
z3-2 - Body ground | Always | 1 MΩ or higher |
z3-1 - Body ground | Always | 1 MΩ or higher |
NG | GO TO STEP 9 |
|
7. | CLEAR DTC |
(a) Connect the connectors to the horn button assembly and airbag sensor assembly. |
|
(b) Connect the cable to the negative (-) auxiliary battery terminal.
(c) Turn the ignition switch to ON, and wait for at least 60 seconds.
(d) Clear the DTCs stored in memory.
Body Electrical > SRS Airbag > Clear DTCs(e) Turn the ignition switch off.
