DTC Summaries
Electronic Airbag SRS: Single Point Sensor – XJ8 1998 MY ON
DTCs are stored in the Single Point Sensor module nonvolatile memory and can be accessed only through
the DLC (data link connector) using PDU.
CAUTION: Measuring the resistance of airbag circuits may cause airbag deployment. Refer to
the service literature for safe testing procedures. Observe all safety precautions when diagnosing
or repairing airbag SRS systems.
