When to use HDS to zero out seat weight sensor?
When to use HDS to zero out seat weight sensor?
If replacing the seat weight sensors and/or the ODS/SWS unit, SWS INITIALIZATION must be done using the HDS to “zero out” the existing calibration. For ODS seat weight sensor inspections 2 and 3, the HDS software requires driving the vehicle 22 mph to properly check the seat weight sensor’s operation and calibration.
When do seat weight sensors need to be recalibrated?
Requires recalibration (SWS Initialization) when seat weight sensors or the ODS/SWS unit is replaced. When seat weight sensors were first added, there was a separate SWS unit mounted under the front passenger’s seat.
Where is the weight sensor on a car?
Passenger Occupancy Sensor, also known as Weight Sensor, Seat Mat, Passenger Occupancy Mat, is installed under the passenger seat’s seat cushion. Its purpose is to send a signal to the airbag module if an adult is sitting on the passenger seat.
Can a faulty seat sensor cause an airbag light to come on?
Before you decide to bypass the passenger seat sensor, use an airbag scanner to verify that the airbag light is due to the seat weight sensor. If yes, call your dealer to check if there is a recall on these problems. Most car manufacturers will replace the passenger seat sensor free of charge even if they are out of warranty.

Why does a Toyota Corolla need zero point calibration?
An uncalibrated sensor might interpret the occupant’s weight as too low or too high and make the wrong call about deploying the airbag. Mendoza showed repair procedures for a 2013 Corolla, which state a zero point calibration must occur “if any of the following conditions” occur:
How to calibrate SRS occupant detection system?
Lean the seat-back to its most upright position (seat-back straight up with zero recline). Drive the vehicle at 22 mph (36 km/h), then park the vehicle on level ground. Turn off the engine and HVAC system. Close the windows and doors. During the calibration procedure, DO NOT sit in or touch the front passenger’s seat.
