NOTE
Upon completion of inspection and repair work, perform the following items.
• Reconnect all air bag system components and ensure all components are properly mounted.
• Clear DTCs referring to “DTC Clearance”, if any.
• Repeat “Air Bag Diagnostic System Check” to confirm that the trouble has been corrected.

Wiring Diagram3 1) With ignition switch OFF, disconnect special tools (B)
and (C) from “L32” connector and SDM connector “L29”
from SDM respectively.
2) Release shorting bar in SDM connector inserting release tool (1) included in special tool (A).
3) Measure voltage from “L29-5” terminal to body ground and from “L29-6” terminal to body ground.
Special tool
(A): 09932-76010

CAUTION!
• Be sure to perform “Air Bag Diagnostic System Check” before starting diagnosis according to flow.
• When measurement of resistance or voltage is required in this flow, use a tester along with a correct terminal adapter from special tool (Connector test adapter kit).
• When a check for proper connection is required, refer to “Inspection of Intermittent and Poor Connections”.
• If there is open circuit in the air bag wire harnes s, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.

DTC Will Set when
The resistance of driver or passenger seat belt pretensioner initiator circuit is above a specified value for specified
time.
Flow Test Description
Step 1: Check if malfunction is in seat belt pretensioner.
