The detecting system for side crash consists of the SRSCM and four Side Impact Sensors (SIS). The SRSCM sets above DTC(s) if it detects that any SIS is defective or there is communication error between any SIS and the SRSCM.
DTC | Condition | Probable cause |
B1412 B1413 B1418 B1419 | ● Open between SIS and SRSCM ● Side Impact Sensor (SIS) Malfunction ● SRSCM Malfunction | ● Wiring Harness ● Side Impact Sensor (SIS) ● SRSCM |
Refer to the DESCRIPTION in this TROUBLESHOOTING part.
PREPARATION
Refer to the DESCRIPTION in this TROUBLESHOOTING part.
CHECK SIS CIRCUIT
Measure resistance between the terminal 1 of SIS harness connector and the terminal 22(23) of SRSCM harness connector(B).
Measure resistance between the terminal 2 of SIS harness connector and the terminal 21(24) of SRSCM harness connector(B).
Specification (resistance) : below 1 Ω
Is the measured resistance within specification?
▶Check Side Impact Sensor.
▶ Repair or replace the wiring harness between the SIS and the SRSCM.
CHECK THE SIDE IMPACT SENSOR
Replace the Side Impact Sensor(SIS) with a new one.
● Refer to "Side Impact Sensor(SIS)" section in this SERVICE MANUAL.
Install the DAB module and connect the DAB connector.
Connect the connectors of the PAB, SAB, CAB, BPT, BUPT, FIS and SIS.
Connect the SRSCM connector.
Connect the battery negative cable to the battery.
Connect a Hi-Scan(Pro) to the data link connector.
Turn the ignition switch to ON and check the vehicle again.
Does Hi-Scan (Pro) indicate any DTC related to Side Impact Sensor(SIS)?
▶ Go to next step.
▶ Replace SIS.
CLEAR THE DTC AND CHECK THE VEHICLE AGAIN
Refer to the DESCRIPTION in this TROUBLESHOOTING part.
