INSPECTION PROCEDURE

1. Preparation

(1) Disconnect the negative (-) terminal cable from the battery, and wait at least 30 seconds.

(2) Remove the DAB module.

(3) Disconnect the connectors of the PAB, left and right side airbags, belt pretensioners and satellite sensors.

(4) Disconnect the SRSCM connector.

Place the DAB with the front surface facing upward.

2. Check satellite circuit (communication error).

[PREPARATION]
Check continuity between the SRSCM connector and the satellite connector as high (+) and high, low (-) and low (-).
OK : Continuity

3. Check the satellite sensor (defect).

[PREPARATION]

[CHECK]
