CHECK CURTAIN SHIELD AIRBAG ASSEMBLY (FRONT PASSENGER SIDE CURTAIN SHIELD SQUIB)
CHECK FLOOR WIRE (FRONT PASSENGER SIDE CURTAIN SHIELD SQUIB CIRCUIT)
DTC B1835/58 Short in Front Passenger Side Curtain Shield Squib Circuit |
DTC B1836/58 Open in Front Passenger Side Curtain Shield Squib Circuit |
DTC B1837/58 Short to GND in Front Passenger Side Curtain Shield Squib Circuit |
DTC B1838/58 Short to B+ in Front Passenger Side Curtain Shield Squib Circuit |
DESCRIPTION
The front passenger side curtain shield squib circuit consists of the center airbag sensor and the front passenger side curtain shield airbag.The circuit instructs the SRS to deploy when the deployment conditions are met.
These DTCs are recorded when a malfunction is detected in the front passenger side curtain shield squib circuit.
| DTC No. | DTC Detection Condition | Trouble Area |
| B1835/58 | Center airbag sensor receives a line short circuit signal 5 times in the front passenger side curtain shield squib circuit during primary check. |
|
| B1836/58 | Center airbag sensor receives an open signal in the front passenger side curtain shield squib circuit for 2 seconds. |
|
| B1837/58 | Center airbag sensor receives a short to ground signal in the front passenger side curtain shield squib circuit for 0.5 seconds. |
|
| B1838/58 | Center airbag sensor receives a short to B+ signal in the front passenger side curtain shield squib circuit for 0.5 seconds. |

INSPECTION PROCEDURE
- HINT:
- Perform the simulation method by selecting the "Check Mode" (signal check) with the intelligent tester (RAV4_ACA30 RM000000XFF05JX.html).
- After selecting the "Check Mode" (signal check), perform the simulation method by wiggling each connector of the airbag system or driving the vehicle on a city or rough road (RAV4_ACA30 RM000000XFF05JX.html).
| 1.CHECK CURTAIN SHIELD AIRBAG ASSEMBLY (FRONT PASSENGER SIDE CURTAIN SHIELD SQUIB) |
 |
Turn the ignition switch off.
Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
Disconnect the connectors from the front passenger side curtain shield airbag.
Connect SST (resistance 2.1 Ω) to connector C.
- CAUTION:
- Never connect a tester to the curtain shield airbag (front passenger side curtain shield squib) for measurement, as this may lead to a serious injury due to airbag deployment.
- NOTICE:
- Do not forcibly insert SST into the terminals of the connector when connecting.
- Insert SST straight into the terminals of the connector.
- SST
- 09843-18061
Connect the cable to the negative (-) battery terminal, and wait for at least 2 seconds.
Turn the ignition switch on (IG), and wait for at least 60 seconds.
Clear the DTCs (RAV4_ACA30 RM000000XFE06SX.html).
Turn the ignition switch off.
Turn the ignition switch on (IG), and wait for at least 60 seconds.
Check the DTCs (RAV4_ACA30 RM000000XFE06SX.html).
- OK:
- DTC B1835, B1836, B1837, B1838 or 58 is not output.
- HINT:
- DTCs other than DTC B1835, B1836, B1837, B1838 or 58 may be output at this time, but they are not related to this check.

| 2.CHECK CONNECTOR |
Turn the ignition switch off.
Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
Disconnect SST from connector C.
Check that the floor wire connector (on the curtain shield airbag RH side) is not damaged.
- OK:
- Lock button is not disengaged, and claw of lock is not deformed or damaged.

| OK | |
| 3.CHECK FLOOR WIRE (FRONT PASSENGER SIDE CURTAIN SHIELD SQUIB CIRCUIT) |
 |
Disconnect the connectors from the center airbag sensor.
Connect the cable to the negative (-) battery terminal, and wait for at least 2 seconds.
Turn the ignition switch on (IG).
Measure the voltage of the wire harness side connector.
- Standard voltage:
- for LHD:
Tester Connection Specified Condition L9-1 (ICR+) - Body ground Below 1 V L9-2 (ICR-) - Body ground Below 1 V - for RHD:
Tester Connection Specified Condition K14-1 (ICL+) - Body ground Below 1 V K14-2 (ICL-) - Body ground Below 1 V
Turn the ignition switch off.
Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
Measure the resistance of the wire harness side connector.
- Standard resistance:
- for LHD:
Tester Connection Specified Condition L9-1 (ICR+) - L9-2 (ICR-) Below 1 Ω L9-1 (ICR+) - Body ground 1 MΩ or higher L9-2 (ICR-) - Body ground 1 MΩ or higher - for RHD:
Tester Connection Specified Condition K14-1 (ICL+) - K14-2 (ICL-) Below 1 Ω K14-1 (ICL+) - Body ground 1 MΩ or higher K14-2 (ICL-) - Body ground 1 MΩ or higher
Release the activation prevention mechanism built into connector B (RAV4_ACA30 RM000000XFD06JX.html).
Measure the resistance of the wire harness side connector.
- Standard resistance:
- for LHD:
Tester Connection Specified Condition L9-1 (ICR+) - L9-2 (ICR-) 1 MΩ or higher - for RHD:
Tester Connection Specified Condition K14-1 (ICL+) - K14-2 (ICL-) 1 MΩ or higher
