PROCEDURE
| 1. |
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 airbag ECU assembly and No. 1 side airbag sensor RH.
OK:
The connectors are properly connected.

CHECK CONNECTORS |
(a) Disconnect the connectors from the airbag ECU assembly and No. 1 side airbag sensor RH.
| (b) Check that the terminals of the connectors are not deformed or damaged. OK: The terminals of the connectors are not deformed or damaged. |
|
| NG | | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
| 3. |
CHECK HARNESS AND CONNECTOR (SHORT) |
| (a) Measure the resistance according to the value(s) in the table below. Standard Resistance:
|
|
| NG | | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
| 4. |
CHECK HARNESS AND CONNECTOR (SHORT TO GROUND) |
| (a) Measure the resistance according to the value(s) in the table below. Standard Resistance:
|
|
| NG | | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
| 5. |
CHECK HARNESS AND CONNECTOR (SHORT TO B+) |
(a) Connect the cable to the negative (-) battery terminal.
(b) Turn the ignition switch to ON.
| (c) Measure the voltage according to the value(s) in the table below. Standard Voltage:
Result:
|
|
(d) Turn the ignition switch off.
(e) 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.
| NG | | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
| 6. |
CHECK HARNESS AND CONNECTOR (OPEN) |
(a) Using a service wire, connect terminals 28 (BCR+) and 29 (BCR-) of connector B.
NOTICE:
Do not forcibly insert the service wire into the terminals of the connector when connecting the wire.
| (b) Measure the resistance according to the value(s) in the table below. Standard Resistance:
Result:
|
|
(c) Disconnect the service wire from connector B.
| NG | | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
| 7. |
CLEAR DTC |
| (a) Connect the connector to the airbag ECU assembly. |
|

(b) Interchange the No. 1 side airbag sensor RH with LH and connect the connectors.
(c) Connect the cable to the negative (-) 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.

C |
HINT:
Codes other than DTCs B009283 and B009783 may be output at this time, but they are not related to this check.
(c) Turn the ignition switch off.
(d) 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.
(e) Return the No. 1 side airbag sensor RH and LH to their original positions and connect the connectors.
| A |
| REPLACE AIRBAG ECU ASSEMBLY |
