DTC B1361 / B1365: Driver / Passenger Side Curtain-Air Bag Initiator Circuit Resistance HighS7RS0B8204043
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 harnes s, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.

DTC Will Set when
The combined resistance of the side curtain-air bag (inflator) module (driver or passenger), harness wiring and
connector terminal contact is above a specified value for specified time.
Flow Test Description
Step 1: Check whether malfunction is in side curtain-air bag (inflator) module.
Step 2: Check side curtain-air bag initiator circuit.

diagram (ground) as if giving an image of water flow.
[A]: Fuse No.
[B]: Circuit jumping page / direction
NOTE
This means “Jump to the page directed with the arrow(s) by their number.
(For example:” Two arrows directing left” means” Jump to two pages before”.)
You will find the same symbol with the arrows directing opposite in the referenced page. The circuit
continues between the symbols.
