DTC 21 – DRIVER AIR BAG INITIATOR CIRCUIT RESISTANCE HIGH
DTC 22 – DRIVER AIR BAG INITIATOR CIRCUIT RESISTANCE LOW
DTC 24 – DRIVER AIR BAG INITIATOR CIRCUIT SHORT TO GROUND
DTC 25 – DRIVER AIR BAG INITIATOR CIRCUIT SHORT TO POWER CIRCUIT
CAUTION:
Be sure to perform AIR BAG DIAGNOSTIC SYSTEM CHECK before starting diagnosis according
to flow table.
When measurement of resistance or voltage is required in this table, use a specified digital multi-
meter (Refer to SPECIAL TOOLS in this section.) along with a correct terminal adapter from special
tool (Connector test adapter kit).
When a check for proper connection is required, refer to INTERMITTENT AND POOR CONNEC-
TIONS in this section.
If there is open circuit in the air bag wire harness, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.
DTC WILL SET WHEN:
DTC 21: The combined resistance of the driver air bag (inflator) module, contact coil assembly, harness wiring
and connector terminal contact is above a specified value for specified time.
DTC 22: The combined resistance of the driver air bag (inflator) module, contact coil assembly, harness wiring
and connector terminal contact is below a specified value for specified time.
DTC 24: The voltage measured at driver air bag initiator circuit is below a specified value for specified time.
DTC 25: The voltage measured at driver air bag initiator circuit is above a specified value for specified time.
TABLE TEST DESCRIPTION:
DTC 21, 22, 24 and 25
STEP 1:Check whether malfunction is in contact coil and driver air bag (inflator) module or the others.
STEP 2:Check driver air bag (inflator) module initiator circuit in air bag harness.
STEP 3:Check whether malfunction is in contact coil or driver air bag (inflator) module.
