Terminal & Connector Inspection
1. Visually inspect all connectors related to the affected circuit for damage and secure connection.
2. Inspect terminals for damage and corrosion.
Avoid damaging connectors during the inspection process.
3. Are any problems found?
►
Go to next step.
►
After repairing the trouble part, check whether DTC occurs or not.
Inspection Procedure
1. PREPARATION
(1) Turn the ignition switch to LOCK.
(2) Disconnect the negative () terminal from the battery and wait for at least 3 minutes.
(3) Remove the DAB module and disconnect the DAB connector.
(4) Disconnect the connectors of the PAB, SAB, CAB, BPT, BUPT, FIS and SIS.
(5) Disconnect the SRSCM connector.
2. CHECK SHORT CIRCUIT
(1) Measure resistance between the terminal 7 and 2 of BS harness connector.
specification(resistance) : infinite
(2) Is the measured resistance within specification?
►
Go to next step.
►
Repair or replace the wiring harness between the BS and the SRSCM.
3. CHECK SHORT TO BATTERY LINE
(1) Connect the negative () terminal to the battery.
(2) Turn the ignition switch to ON.
(3) Measure voltage between the terminal 7 of BS harness connector and chassis ground().
specification(voltage) : Approximately 0 V
(4) Is the measured voltage within specification?
►
Check the BS.
►
Repair the short to battery line circuit on wiring harness between the BS and the SRSCM.
4. CHECK THE SEAT BELT BUCKLE SWITCH (BS)
(1) Measure current between the terminal 7 of BS and 34(31) of SRSCM.
Specification(current) : 12 ~ 17 mA (Buckled status), 4 ~ 7 mA (Unbuckled status)
