B1035
DTC B1035: Driver Air Bag (2nd Stage) Circuit Resistance High
Wiring Diagram
DTC Will be Set when
The combined resistance of the driver air bag (inflator) module (2nd stage), contact coil assembly, harness wiring and connector terminal contact is above a specified value for specified time.
Flow Test Description
Step 2: Check whether malfunction is in contact coil and driver air bag (inflator) module (2nd stage) or the others.
Step 3: Check driver air bag (inflator) module (2nd stage) initiator circuit.
Step 4: Check whether malfunction is in contact coil or driver air bag (inflator) module (2nd stage).
DTC Troubleshooting
1.
Was "Air Bag Diagnostic System Check" performed?
YES -
Go to Step 2.
NO -
Go to Air Bag Diagnostic System Check Air Bag Diagnostic System Check:Advanced Air Bag.
2. With ignition switch OFF, disconnect contact coil connector located under of the steering column.
Check proper connection to contact coil at terminal in "G27" connector.
If OK, then connect special tools (B) and (C) to "G27" connector disconnected in Step 1).
Special Tool
(B): 09932-75010
(C): 09932-77320
Check SDM DTC.
NOTE:
At this time, DTC B1031 may be output, but it is not related to this check.
With ignition switch ON, is DTC B1035 indicated?
YES -
Go to Step 3.
NO -
Go to Step 4.
3. With ignition switch OFF, disconnect SDM connector "G46".
Check proper connection to SDM at terminals "G46-3" and "G46-4".
If OK, release shorting bar in SDM connector inserting release tool (1) included in special tool (A).
Measure resistance between "G46-3" and "G46-4" terminals with connected special tools (B) and (C).
Special Tool
(A): 09932-76010
(B): 09932-75010
(C): 09932-77320
Is resistance 5.5 ohms or less?
YES -
Substitute a known-good SDM and recheck.
NO -
High resistance or open wire in "BRN/RED" or "BRN/BLK" circuit.
4. With ignition switch OFF, disconnect special tools (B) and (C) from "G27" connector and then reconnect contact coil connector located under of the steering column.
Remove driver air bag (inflator) module from steering wheel referring to Removal and Installation Driver Air Bag (Inflator) Module Removal and Installation:Advanced Air Bag.
Check proper connection to driver air bag (inflator) module connector (connector color is black).
If OK, then connect special tools (A), (B) and (D) to driver air bag (inflator) module connector (connector color is black).
Special Tool
(A): 09932-76010
(B): 09932-75010
(C): 09932-77320
(D): 09932-78310
Check SDM DTC.
NOTE:
At this time, DTC B1031 may be output, but it is not related to this check.
With ignition switch ON, is DTC B1035 indicated?
YES -
Turn ignition switch OFF. Replace contact coil assembly referring to Contact Coil Cable Assembly Removal and Installation Contact Coil Cable Assembly Removal and Installation.
NO -
Turn ignition switch OFF. Replace driver air bag (inflator) module referring to Removal and Installation Driver Air Bag (Inflator) Module Removal and Installation:Advanced Air Bag.
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, if any. DTC Clearance
- Repeat Air Bag Diagnostic System Check Air Bag Diagnostic System Check:Advanced Air Bag
to confirm that the trouble has been corrected.
