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”.

Is each measured resistance 1
Ω or less? Go to Step 2. High resistance or open
wire in “ORN” circuit or
“PNK/BLK” circuit.
2 1) Disconnect service wire from “E13” connector. 2) Measure voltage between “L29-50” terminal and body ground, “L29-51” terminal and body ground.
