DTC code
B1018
Windshield Wiper Low Control
Label auto-translated from another language and machine-checked. On manufacturer-specific codes the meaning can differ per platform — confirm with the scanner on the actual ECU.
Technical guide
Symptoms
- Airbag (SRS) warning light illuminated on the dashboard
- potential problems with the occupant detection/airbag system (airbag may not behave correctly for the seat occupant).
Probable causes
- Wiring harness disconnection
- faulty Occupant Detection System seat sensor
- defective Occupant Detection System control unit
- malfunctioning air bag diagnosis sensor unit. Contributing factors per sources: corrosion or damage to sensor components
- or impact/damage to the passenger seat affecting the sensor.
Diagnostic steps
- Read the code from the SRS/air bag diagnosis sensor unit with a capable scan tool.
- Inspect the occupant detection system wiring harness and connectors under the passenger seat for disconnection, corrosion or damage; reconnect/repair as needed.
- If wiring is good, test the occupant detection seat sensor; replace if faulty.
- If the sensor tests good, suspect the Occupant Detection System control unit, then the air bag diagnosis sensor unit.
- Clear the code and confirm the SRS light extinguishes and the occupant detection system reports correctly. This is a restraint-system fault affecting airbag deployment — address promptly.
