7 ~ 16V
Check all the connectors related to the DTC for contact condition visually.
Check the connector and the terminal.
Check the connector for connection securely.
Check the terminal for contact condition,deterioration,erosion and elasticity.
Do not deform the connector for revising contact.
Are confirmed trouble on the connector and the terminal?
▶ After repairing the trouble part, check whether DTC occurs or not.
▶ Check the source voltage.
Preparation
Disconnect the negative(-) terminal cable from the battery,and wait 30 seconds.
Remove the DAB module.
Disconnect the connector of the PAB, SAB, CAB, SIS,FIS and BPT.
Disconnect the SRSCM connector.
Check the source voltage
Connect the negative(-) terminal cable to the battery.
Turn the ignition switch " ON ".
Measure voltage between the battery supply terminal 23 of the SRSCM connector and body ground.
Does the normal voltage?
▶ Check the harness between the battery and the SRSCM. Check the battery and charging system
▶ Check the SRS SRI.
Turn the ignition switch " LOCK ".
Connect the DAB module.
Connect the connector of the PAB,SAB,CAB,SIS,FIS and BPT.
Connect the SRSCM connector.
Turn the ignition switch " ON ".
Does the SRS SRI turn off?
▶ Check for DTCs.If a DTC is output, perfrom troubleshooting for the DTC. If B1101 or B1102 is output,replace the SRSCM.
▶ From the result of the above inspection, the malfunctioning part can now be considered normal.
