Monitor Scantool Data
- Ignition "OFF", connect scantool.
- Ignition "ON" & Engine "OFF", select "Current Data" mode.
- Monitor the "All airbag resistance" parameter on the Scantool.
Specification: 1.1Ω < Resistance of airbag < 6.7Ω
Reference: In a case of an open in the airbag circuit : FAIL
In a case of a short to battery in the airbag circuit: FAIL
In a case of a short to ground in the airbag circuit : FAIL
- Is parameter displayed within specifications?
YES
- Displaying nothing (no DTC) or DTC with label "H" (historical) shows that Fault is intermittent caused by poor contact in the part's and/or SRSCM connector or was repaired and SRSCM memory was not cleared.
Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
- Repair or replace as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
NO
- Check for short between ignition circuits of DAB, PAB, BPT, CAB, SAB. If the condition of harness and component is OK, this fault is caused by SRSCM internal error so replace a known-good SRSCM and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- Displaying nothing (no DTC) or DTC with label "H" (historical) shows that Fault is intermittent caused by poor contact in the part's and/or SRSCM connector or was repaired and SRSCM memory was not cleared.
