Monitor KDS Data
- Ignition "OFF", connect KDS.
- Ignition "ON"& Engine "OFF", select "Current Data" mode.
- Monitor the "All airbag resistance" parameter on the KDS.
Specification:
Resistance of driver airbag (1st stage) greater than 1.4Ω
Resistance of driver airbag (1st stage) less than 7.0Ω
Specification:
Resistance of airbag greater than 1.0Ω
Resistance of airbag less than 7.0Ω
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
- 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.NOTE: Do not handle or strike the SRCM with the ignition "ON". The seat belt Pretensioner, curtain airbag or side airbag could be caused serious injury. Please handle with care.
NO
- Check for short between ignition circuits of DAB, PAB, BPT, CAB, SAB, APT 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.
