Airbag(Event #1)
B1493 PODS(Passenger Occupant Detecting System) Communication error - Inspection/Repair:_:W/Harness Inspection

Terminal and Connector Inspection

1. Many malfunctions in the electrical system are caused by poor harness and terminals.
Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check shorting bar/shorting bar release pin and connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?






Power Circuit Inspection

Check for an open or short circuit in the WCS Power Circuit.
1. Disconnect WCS connector from wiring harness.
2. Ignition "ON" & Engine "OFF".
(1) Measure voltage between terminal "supply voltage" and chassis ground.

Specification :Battery Voltage




3. Is the measured voltage within specifications?






CAN communication Line Inspection

1. Connect SRSCM and Weight Classification System connector.
2. IG KEY ON.
3. Measure signal waveform between C-CAN HIGH terminal and C-CAN LOW terminal of SRSCM connector.

Specification :Refer to Signal waveform and Data




4. Is the measrured signal waveform normal ?






WCS Reset

1. Ignition "OFF", connect scantool.
2. Ignition "ON"& Engine "OFF", select Weight Classification System and select "WCS Reset" mode.
3. You will see comments and current weight measured.
4. Make sure the measure weight is caused by occupant or tools or interference.
5. And then press "ENTER"

















Specification :Approx. - 4.0 kg ~ + 4.0 kg

6. The 'WCS Reset' operation will take 3 - 10 second.
7. Make sure that there should not be vibration or weight adding to the passenger front seat.












8. If the 'WCS Reset' operation is finished successfully, you will see the following screen.
