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 front airbag sensor LH.
OK:
The connectors are properly connected.

| 2. |
CHECK CONNECTORS |
(a) Disconnect the connectors from the airbag ECU assembly and front airbag sensor LH.
| (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 30 (+SL) and 31 (-SL) 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 front airbag sensor LH with RH 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.
|
| 8. |
CHECK FRONT AIRBAG SENSOR LH |
(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 |
|---|---|
| B009083 is output |
A |
| B009583 is output |
B |
| B009083 and B009583 are not output |
C |
HINT:
Codes other than DTCs B009083 and B009583 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 front airbag sensor LH and RH to their original positions and connect the connectors.
| A |
| REPLACE AIRBAG ECU ASSEMBLY |
| B |
| REPLACE FRONT AIRBAG SENSOR LH |
