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 tester along with a cor-
rect terminal adaptor 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 B1015 :
The combined resistance of the passenger air bag (inflator) module, harness wiring and connector terminal con-
tact is above a specified value for specified time.
DTC B1016 :
The combined resistance of the passenger air bag (inflator) module, harness wiring and connector terminal con-
tact is below a specified value for specified time.
DTC B1018 :
The voltage measured at passenger air bag initiator circuit is below a specified value for specified time.
DTC B1019 :
The voltage measured at passenger air bag initiator circuit is above a specified value for specified time.
TABLE TEST DESCRIPTION
DTC B1015, B1016, B1018 and B1019 :
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 B1019 only)
