DTC | B1351 PAB, open cirucit (R = ∞) B1352 PAB resistance too high (R ≥ 6.0Ω) B1353 PAB resistance too low (R ≤ 1.1Ω) |
DTC Detecting Condition | Trouble Area |
● Too high or low resistane between PAB high (+) wiring harness and PAB low (-) wiring harness of squib. ● PAB malfunction ● SRSCM malfunction | ● PAB squib ● SRSCM ● Wire harness |
Preparation
Disconnect the negative (-) terminal cable from the battery, and wait at least 30 seconds.
Remove the DAB module.
Disconnect the connectors of the PAB, left and right side airbags, belt pretensioners and satellite sensors.
Disconnect the SRSCM connector.
Place the DAB with the front surface facing upward.
Check the PAB resistance.
[PREPARATION]
Release the airbag activation prevention mechanism on the SRSCM side of the airbag squib side. Connect the dummy (0957A-38200) and dummy adapter (0957A-38300) to PAB connector of the SRSCM connector side.
Before checking the resistance, you have to insert the shorting bar insert plastic that is attached to the diagnosis checker into the SRSCM connector.
[CHECK]
Measure the resistance between the PAB high (+) and the PAB low (-).
1.4Ω ≤ R ≤ 4.7Ω
Check the PAB squib.
Turn the ignition switch to LOCK.
Disconnect the negative (-) terminal cable from the battery, and wait for 30 seconds.
Connect the PAB connector.
Connect the negative (-) terminal cable to the battery, and wait for 30 seconds.
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 30 seconds.
Turn the ignition switch to ON, and wait for 30 seconds.
Using Hi-Scan Pro, check the DTC.
There is no DTC.
[HINT]
Codes other than these may be output at this time, but they are not relevant to this procedure.
