Are confirmed trouble on the connector and the terminal?
▶ After repairing the trouble part, check whether DTC occurs or not.
▶ Check the SIS circuit.
The release system for the SRS consists of the SRSCM and SIS.
The above DTC is recorded when a defect is detected in the SIS circuit.
Condition | Probable cause |
- SIS malfunction - SRSCM malfunction | - SIS - SRSCM - Wire harness |
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 SIS circuit.
Preparation
Turn the ignition switch " LOCK ".
Connect the SIS connector.
Connect the SRSCM connector.
Connect the negative (-) terminal cable from the battery, and wait for 30 seconds.
Check
Turn the ignition switch to " ON ", and wait for at least 30 seconds.
Clear the malfunction code stored in the memory with the HI-Scan Pro.
Turn the ignition switch to " LOCK ", and wait for at 30 seconds.
Turn the ignition switch to " ON ", and wait for at 30 seconds.

Codes other than these may be output at this time, but they are not relevant to this procedure.
There is no DTC.
▶ From the result of the above inspection, the malfunctioning part can now be considered normal.
▶ Replace the SIS(see page RT- 24).
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 SIS circuit
Check continuity between the SRSCM connector and the SIS connector as high(+)and high(+), low(-) and low(-).
OK : Continuity
▶ Check the SIS.
▶ Replace the harness between the SRSCM and SIS.
