The side collision sensor RH circuit consists of the airbag sensor assembly, No. 1 side airbag sensor RH and Rear Floor Side Airbag Sensor.
The No. 1 side airbag sensor RH detects impacts to the vehicle and sends signals to the airbag sensor assembly to determine if the SRS should be deployed.
DTC B162C is stored when a malfunction is detected in the circuit for the side collision sensor RH circuit.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | Warning Indicate | Test Mode / Check Mode |
|---|---|---|---|---|---|

After the engine switch is turned off, there may be a waiting time before disconnecting the negative (-) battery terminal.
When disconnecting and reconnecting the battery
When disconnecting and reconnecting the battery, there is an automatic learning function that completes learning when the respective system is used.
After replacing the airbag sensor assembly, refer to initialization.
Turn the engine switch on (IG), and wait for at least 60 seconds.
Check for DTCs.
