Has a problem been found?
YES
a.
Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
a.
Go to " Squib Circuit Inspection" procedure.
Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
Thoroughly check shorting bar/shorting bar release pin and connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
Has a problem been found?
YES
Repair as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
Go to " Squib Circuit Inspection" procedure.
Ignition "OFF".
Disconnect (-) terminal cable from battery and wait for 1 minutes or more.
Disconnect PCAB module and connect the dummy (0957A-38200) and dummy adapter (0957A-2G000) to main harness connector.
If dummy and dummy adaptor are not able to be prepared, use a known-good PCAB or 2Ω resistor.
Connect (-) terminal cable to battery and Ignition "ON" & Engine "OFF" and wait for 30 seconds or more.
Connect scantool to Data Link Connector(DLC) and clear DTC with scantool and diagnose again.
Is DTC present problem ?
YES
Go to "Main harness circuit inspection" procedure.
NO
Substitute a known-good PCAB assembly, and check for proper operation.
If the problem is corrected, replace PCAB and then go to "Verification of Vehicle Repair" procedure.
Ignition "OFF"
Disconnect the battery (-) terminal cable from the battery and wait at least one minutes.
Disconnect PCAB connector and SRSCM main harness connector.
Measure resistance between terminal "2" and "1" of the PCAB harness connector.
Specification : approx. 1 Ω below
Is the measured resistance within specifications?
YES
Substitute a known-good SRSCM, and check for proper operation.
If the problem is corrected, replace SRSCM and then go to "Verification of Vehicle Repair" procedure.
NO
Substitute the SRS main harness and check for proper operation.
If the problem is corrected, replace SRS main harness and then go to "Verification of Vehicle Repair" procedure.
