belt pretensioner initiator circuit.
Pass Preten Ini Res (Passenger pretensioner
initiator resistance) (ohm)
This parameter indicates the resistance of the passenger
seat belt pretensioner initiator circuit.
Driv Sidebag Ini Res (Driver side-air bag initiator
resistance) (ohm)
This parameter indicates the resistance of the driver
side-air bag initiator circuit.
Pass Sidebag Ini Res (Passenger side-air bag
initiator resistance) (ohm)
This parameter indicates the resistance of the
Passenger side-air bag initiator circuit.
Driv curtain Ini Res (Driver side curtain-air bag
initiator resistance) (ohm)
This parameter indicates the re sistance of the driver side
curtain-air bag initiator circuit.
Pass curtain Ini Res (Passenger side curtain-air bag
initiator resistance) (ohm)
This parameter indicates the resistance of the passenger
side curtain-air bag initiator circuit.

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.

“AIR BAG” Warning Right Does Not Come ONS7RS0B8204008
Wiring Diagram6 1) Disconnect combination meter connector “G28” referring
to “Combination Meter Removal and Installation in
Section 9C”.
2) Check proper connection to combination meter at “YEL/ BLK” terminal for “AIR BAG” warning right and to SDM at
terminal “L29-2”.
3) If OK, then check resistance between “YEL/BLK” wire terminal of combination meter connector “G28” and
“L29-2” terminal of SDM connector.
Special tool
(A): 09932-76010
Is resistance 1
Ω or less? Substitute a known-
good SDM and recheck.
If “AIR BAG” warning
right remain lighting,
replace combination
meter.
“YEL/BLK” wire
(between combination
meter and SDM
connector) open or
short to ground.

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 adapter 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.

Flow Test Description
Step 1: Check combination meter power feed circuit.
Step 2: Check “AIR BAG” warning right 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.

1 1) Set parking brake.
2) Note combination me ter when ignition switch is turned
ON.
Does the “BRAKE” in dicator (warning right) come ON? Go to Step 2. Check and correct the
following possible
cause. • Open circuit in
“GRN” or “WHT/RED”
wire. • Short circuit
between “GRN” or
“WHT/RED” and
ground. • “METER” fuse
blown.
2 1) Disconnect SDM connector “L29”.
2) Note combination me ter when ignition switch is turned
ON.
Does the “AIR BAG” warning right come ON? Substitute a known-
good SDM and recheck.

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 B1014: “AIR BAG” Warning Right Circuit FailureS7RS0B8204011
Wiring DiagramStep Action Yes No
1 1) With ignition switch OFF, disconnect SDM connector “L29”.
2) Check “L29-35” terminal of SDM.
