DTC B1043: Passenger Air Bag Initiator Circuit Short to Ground

S5JB0A8204024

Wiring Diagram
Refer to “DTC B1041: Passenger Air Bag Initiator Circuit Resistance High”.

CAUTION

!

 

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

 

DTC Will Set when
The voltage measured at passenger air bag (initiator) circuit is below 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) 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 B1043 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”.

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).

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.

1) With ignition switch OFF, disconnect special tools (B) 

and (C) from “G67” connector and SDM connector “G47” 
or “G46” from SDM respectively.

2) Release shorting bar in SDM connector inserting release 

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

3) Measure resistance between “G47-3” and body ground, 

and between “G47-4” and body ground [A] or between 
“G46-5” and body ground, and between “G46-6” and 
body ground [B].

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

Is resistance infinity?

Substitute a known-
good SDM and recheck.
