1

Is vehicle equipped with “AIR BAG” monitor connector?

Go to Step 2.

Go to Step 3.

2

Check “AIR BAG” monitor coupler.

Is the diagnosis switch terminal in “AIR BAG” monitor 
coupler connected to body ground with service wire?

Remove service wire.

Go to Step 3.

3

1) With ignition switch OFF, disconnect SDM connector 

“G47” or “G46”.

2) Check “G47-14” or “G46-12” terminal of SDM connector.

Is it shorted to ground terminal or harness?

Clean up terminal or 
harness.

Substitute a known-
good SDM and recheck.

“AIR BAG” Warning Light Cannot Indicate Flashing Pattern of DTC (If Equipped with “AIR BAG” 
Monitor Coupler)

S6JB0B8204010

Wiring Diagram
Refer to ““AIR BAG” Warning Light Flashes”.

CAUTION

!

 

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

 

Flow Test Description
Step 1: Check “AIR BAG” monitor coupler.
Step 2: Check for open circuit in air bag diagnosis switch circuit.

Troubleshooting

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.
• Repeat “Air Bag Diagnostic System Check” to confirm that the trouble has been corrected.

 

Step

Action

Yes

No

1

Inspect connection between diagnostic switch terminal on 
“AIR BAG” monitor coupler and body ground with service 
wire.

Are they connected securely with service wire?

Go to Step 2.

Properly connect 
diagnostic switch 
terminal on “AIR BAG” 
monitor coupler and 
body ground with 
service wire.

2

1) Disconnect SDM connector from SDM.
2) Check for proper connection at “PPL” wire (“G47-14” 

terminal or “G46-12” terminal of SDM connector and 
“G34-2” terminal of “AIR BAG” monitor coupler (1)) 
terminals.

3) If OK, then measure resistance between “G47-14” 

terminal [A] or “G46-12” terminal [B] and “G34-2” 
terminal.

Special tool
(A):  09932–76010 

Is resistance 1 

Ω

 or more?

Check “PPL” wire 
terminals. If OK, repair 
high resistance or open 
in “PPL” wire circuit.

Substitute a known 
good SDM and recheck.

8B-24 Air Bag System: 

DTC B1013: SDM fault

S6JB0B8204011

DTC Will Set when
An internal SDM fault is detected by SDM.

NOTE
DTC B1013 can never be cleared once it has been set.

 

DTC Troubleshooting

1) Turn ignition switch OFF.
2) Replace SDM.
3) Repeat “Air Bag Diagnostic System Check”.

DTC B1016: Power Source Voltage High

S6JB0B8204012

Wiring Diagram

CAUTION

!

 

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

 

DTC Will Set when
The power source voltage to SDM is above specified value for specified time.

Flow Test Description
Step 1: Check if voltage applied to SDM is within normal range.
Step 2: Check if DTC B1016 still exists.

DTC Troubleshooting

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.

 

Step

Action

Yes

No

1

1) With ignition switch OFF, disconnect SDM connector.
2) Check proper connection to SDM at “G47-16” or “G46-

11” terminal.

3) If OK, turn ignition switch ON and then check voltage 

between “G47-16” [A] or “G46-11” [B] terminal on SDM 
connector and body ground.

Special tool
(A):  09932–76010

Is voltage 14 V or less?

Go to Step 2.

Check charging system 
and repair as necessary 
referring to “Generator 
Test (Overcharged 
Battery Check) in 
Section 1J”.

2

1) With ignition switch OFF, reconnect SDM connector.

With ignition switch ON, is DTC B1016 indicated?

Substitute a known-
good SDM and recheck.

Intermittent trouble. 
Check for intermittent 
trouble referring to 
“Inspection of 
Intermittent and Poor 
Connections” If OK, 
substitute a known-
good SDM and recheck.
