S5JB0A8204010

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”.

S5JB0A8204012

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.

DTC B1017: Power Source Voltage Low

S5JB0A8204013

Wiring Diagram
Refer to “DTC B1016: Power Source Voltage High”.

CAUTION

!

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

DTC Will Set when
The power source voltage is below specified value for specified time.

Flow Test Description
Step 1: Check if voltage on battery is within normal range.
Step 2: Check if voltage applied to SDM is within normal range.
Step 3: Check if voltage applied to “L04” connector is within normal range.
Step 4: Check if DTC B1017 still exists.

Go to Step 2.

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

2

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.
