DTC B1041: Passenger Air Bag Initiator Circuit Resistance High

S6JB0B8204019

Wiring Diagram

CAUTION

!

Be sure to observe instructions under CAUTION in “Air Bag Diagnostic System Check Flow”.

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. (Between “G68” and “G65”)
Step 3: Check passenger air bag (inflator) module initiator circuit. (Between “G67” and “G47” or “G67” and
“G46”)

1

1) With ignition switch OFF, disconnect passenger air bag

(inflator) module connector.

2) Check proper connection to passenger air bag (inflator)

module at terminals in “G65” connector.

3) If OK, then connect special tools (A), (B) and (D) to

“G65” connector.

Special tool
(A): 09932–76010
(B): 09932–75010
(D): 09932–78310

4) Check SDM DTC.

With ignition switch ON, is DTC B1041 indicated?

Go to Step 2.

Turn ignition switch
OFF. Replace
passenger air bag
(inflator) module
referring to “Passenger
Air Bag (Inflator) Module
Removal and
Installation”.

2

1) With ignition switch OFF, disconnect “G67” connector

located near the glove box.

2) Check proper connection to instrument panel harness

connector at terminal “G67-1” and “G67-2”.

3) If OK, then connect special tools (B) and (C) to “G67”

connector disconnected in Step 1).

Special tool
(B): 09932–75010
(C): 09932–77320

4) Check SDM DTC.

With ignition switch ON, is DTC B1041 indicated?

Go to Step 3.

High resistance or open
wire “BLU/RED” or
“YEL/RED” circuit.

8B-44 Air Bag System:

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.

3

1) With ignition switch OFF, disconnect SDM connector

“G47” or “G46”.

2) Check proper connection to SDM at terminals “G47-3”

and “G47-4” or “G46-5” and “G46-6”.

3) If OK, release shorting bar in SDM connector inserting

release too (1) included in special tool (A).

4) Measure resistance between “G47-3” and “G47-4”

terminals [A] or between “G46-5” and “G46-6” terminals
[B] with connected special tools (B) and (C).

Special tool
(A): 09932–76010
(B): 09932–75010
(C): 09932–77320

Is resistance 5.5

Ω

or less?

Substitute a known-
good SDM and recheck.

High resistance or open
wire in “BLU/RED” or
“YEL/RED” circuit.
(Between “G67” and
“G47” connectors or
between “G67” and
“G46” connectors).
