DTC B1475 CURTAIN AIRBAG FRONT-DRIVER RESISTANCE CIRCUIT SHORT TO GROUND
DTC B1479 CURTAIN AIRBAG FRONT-PASSENGER RESISTANCE CIRCUIT SHORT TO GROUND

DESCRIPTION
The CAB squib circuit consists of the SRSCM and CAB. It causes the SRS to deploy when the SRS deployment conditions are satisfied. The above DTC is recorded when a short to ground is detected in the CAB squib circuit.

Detecting Condition:

INSPECTION OF CONNECTOR AND TERMINAL
1. Check all the connectors related to the DTC for contact condition visually.
2. Check the connector and the terminal.
1. Check the connector for connection securely.
2. Check the terminal for contact condition, deterioration, erosion and elasticity.

CAUTION: Do not deform the connector for revising contact.

3. Are confirmed trouble on the connector and the terminal?

YES - After repairing the trouble part, check whether DTC occurs or not.

NO - Check the CAB squib circuit.

CHECK CAB SQUIB CIRCUIT
1. Preparation
1. Disconnect the negative (-) terminal cable from the battery, and wait 30 seconds.
2. Remove the DAB module.
3. Disconnect the connector of the PAB, SAB, CAB, SIS, FIS and BPT.
4. Disconnect the SRSCM connector.






2. Check CAB squib circuit
For the connector (on the SRSCM side) between the SRSCM and CAB, measure the resistance between the CAB high (+) and body ground.

Resistance : Infinity






YES - Check the CAB squib.

NO - Replace the harness between the SRSCM and CAB.

CHECK CAB SQUIB
1. Preparation
