Diagnostic Procedure with Diagnostic Trouble Code (DTC)
OCCUPANT DETECTION SYSTEM (DIAGNOSTICS)
E: DTC 29 ODS FAILURE
DTC DETECTING CONDITION:
•Occupant detection sensor is faulty.
•Occupant detection control module is faulty.
•Occupant detection harness is faulty.
•Rear airbag harness is faulty.
•Fuse No. 25 (in joint box) is blown.
Step Check Yes No
1 CHECK POOR CONTACT OF CONNEC-
TORS.
Check for poor contact of the connectors
between the occupant detection control mod-
ule and airbag control module.
Is there poor contact? Reconnect the
connector. If the
fault is not fixed,
replace the airbag
harness.
Go to step 2.
2 CHECK DIAGNOSTIC TROUBLE CODE
(DTC).
READ DIAGNOSTIC TROUBLE CODE (DTC)
FOR THE AIRBAG SYSTEM.
Is “2C Belt Tension Sensor fail-
ure or 37 Buckle Switch failure”
displayed in the diagnostics
code?
Pe r for m t h e d ia g -
nosis according to
each DTC.
Check the seat
harness, and if any
fault is found,
replace the seat
harness. If the
fault is not fixed,
replace the occu-
pant detection sys-
tem.
