Are confirmed trouble on the connector and the terminal?
▶ After repairing the trouble part, check whether DTC occurs or not.
▶ Check the DAB squib circuit.
The DAB squib circuit consists of the SRSCM, the clock spring and the DAB.The circuit causes the airbag to deploy when the airbag deployment conditions are satisfied.The above DTC is recorded when a short to ground is detected in the DAB squib circuit.
Condition | Probable cause |
- Short circuit is squib wire harness(to ground) - DAB squib malfunction - Clock spring malfunction - SRSCM malfunction | - DAB squib - Clock spring - 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 DAB squib circuit.
Preparation
Turn the ignition switch " LOCK ".
Connect the DAB 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.
Using Hi-Scan Pro, check the DTC.
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 DAB(see page RT- 18).
Disconnect the connector between the SRSCM and the clock spring.
Measure the resistance between the DAB high(+) on the clock spring side of the connector between the clock spring and the DAB and body ground.and low(-).
Resistance : ∞
▶ Replace the harness between the SRSCM and the clock spring.then check the DAB squib circuit(see page RT- 18).
▶ Replace the clock spring(see page RT- 19).
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 DAB squib circuit
For the connector(on the clock spring side) between the clock spring and the DAB, measure the resistance between the DAB high and body ground.
Resistance : ∞
▶ Check the DAB squib.
▶ Check the clock spring circuit.
