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 15: The combined resistance of the passenger air bag (inflator) module, harness wiring and connector ter-
minal contact is above a specified value for specified time.
DTC 16: The combined resistance of the passenger air bag (inflator) module, harness wiring and connector ter-
minal contact is below a specified value for specified time.
DTC 18: The voltage measured at passenger air bag initiator circuit is below a specified value for specifie time.
DTC 19: The voltage measured at passenger air bag initiator circuit is above a specified value for specifie time.
TABLE TEST DESCRIPTION:
DTC 15, 16, 18 and 19
STEP 1:Check whether malfunction is in passenger air bag (inflator) module.
STEP 2:Check passenger air bag (inflator) module initiator circuit in air bag harness.
STEP 3:Check passenger air bag (inflator) module initiator circuit in air bag harness (for DTC 18 and 19 only).
