DTC B1041: Passenger Air Bag Initiator Circuit Resistance HighS7RS0B8204022
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 adaptor 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 passenger air bag (inflator)  module, harness wiring and connector terminal contact is 
above a specified value for specified time.
Flow Test Description
Step 1: Check if malfunction is in passenger air bag (inflator) module.
Step 2: Check passenger air bag (inflator) module initiator circuit. (in instrument panel harness)
Step 3: Check passenger air bag (inflator)  module initiator circuit. (in floor harness)
