5. This test determines whether the malfunction is in
CKT IB06±YEL/BLK.
6. This test determines whether the malfunction is in
the SRS coil assembly or the driver air bag
assembly.Diagnostic Aids:
An intermittent condition is likely to be caused by a short
to ground in the driver air bag assembly circuit. Inspect
CKTs IB05±YEL and IB06±YEL/BLK carefully for cutting
or chafing.

DTC 25 Driver Deployment Loop Short To Ignition
CAUTION: When DTC 25 has been set, it is necessary to replace the SDM. Setting DTC 25 will also cause DTC
71 to set. When a scan tool ªCLEAR CODESº command is issued and the malfunction is no longer present,
DTC 71 will remain current. Ensure that the short to voltage condition is repaired prior to installing a
replacement SDM to avoid damaging the SDM.
