DTC B1015: Passenger Air Bag Initiator Circuit Resistance High
Wiring Diagram
[A]: Shorting bar 2. Ignition switch 4. SDM 6. Ground for air bag system
1. From main fuse 3. “AIR BAG” fuse 5. Passenger air bag (inflator) module    
Be sure to perform Air Bag Diagnostic System Check before starting diagnosis according to the flow.
When measurement of resistance or voltage is required in this flow, use a specified digital multimeter (Refer to Special Tool .) along with a correct terminal adaptor from special tool (Connector test adapter kit).
When a check for proper connection is required, refer to Inspection of Intermittents and Poor Connections .
If there is open circuit in the air bag wire harness, connector or terminal is found damaged, replace the wire harness, connector and terminal as an assembly.
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 whether malfunction is in passenger air bag (inflator) module.
Step 2: Check passenger air bag (inflator) module initiator circuit in air bag harness.
Step Action YES NO
1) With ignition switch OFF, disconnect passenger air bag (inflator) module connector “G62” behind the glove box.
2) Check proper connection to passenger air bag (inflator) module at terminals in “G62” connector.
3) If OK, then connect special tools (B) and (C) to passenger air bag (inflator) module connector “G62”.

(B) : 09932–75010
(C) : 09932–78340
With ignition switch ON, does DTC B1015 still exist?
Go to Step 2.
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 SDM connector “G102”.
2) Check proper connection to SDM at terminals “G102-7” and “102-8”.
3) If OK, release shorting bar in SDM connector inserting release tool (1) included in special tool (A).
4) Measure resistance between “G102-7” and “G102-8” terminals with special tool (B) and (C) connected to “G62” connector.

(B) : 09932–75010
(C) : 09932–78340
Is resistance 4.5 Ω or less?
Substitute a known-good SDM and recheck.
Repair high resistance or open in “YEL/RED” or “YEL” wire circuit.
Upon completion of inspection and repair work, perform the following items.
Reconnect all air bag system components, ensure all components are properly mounted.
Clear DTCs (Refer to DTC Clearance .), if any.
Repeat Air Bag Diagnostic System Check to confirm that the trouble has been corrected.
