Wiring Diagram
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 harness, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.
DTC Will Set when
The resistance measured between side-sensor circuit and ground circuit is below a specified value for specified time.
Flow Test Description
Step 1: Check for short circuit between side-sensor circuit and ground.
Step 2: Check if malfunction is in side-sensor.
