PODS-F
B1493 OCS(Occupant Classification System) Communication error - General Information

Component Location





General Description

In order to make normal activation of airbag system, SRSCM detects DTC(s) for the Passenger side Body Detection System.
If the seat is accupied, Bodysense sensor detects how passenger weighs and send signal to ACU via CAN.
ACU rcognizes the signal as 3(three) different classifications; that is, 0(Empty), 1(Small), 2(Large).
With these signal, ACU determines whether it needs to deploy PAB(Passenger Airbag) or not.

DTC Description

The Passenger side PODS-F sensor Mat & ECU sets DTC B1493 if there is an error in communication between Passenger side PODS-F sensor Mat & ECU and SRSCM.
DTC is set if Passenger side PODS-F sensor Mat & ECU can't receive any message from SRSCM via CAN communication (No communication)
