DTC Detecting Condition and Trouble Area






DTC Troubleshooting

1.
Was "Air Bag Diagnostic System Check Flow" performed?
YES -
Go to Step 2.
NO -
Go to Air Bag Diagnostic System Check Flow Air Bag Diagnostic System Check Flow:Advanced Air Bag.

2. Front side-air bag circuit check

Remove applicable driver-side / passenger-side front side-air bag (inflator) module from seat back referring to Removal and Installation Front Side-Air Bag (Inflator) Module Removal and Installation:Advanced Air Bag.
Check for proper connection to applicable front side-air bag (inflator) module at terminal in connector "Q104" or "Q105".
If OK, then connect special tools (A), (B) and (C) to applicable front side-air bag (inflator) connector "Q104" or "Q105".
Special Tool

(A): 09932-76010

(B): 09932-75010

(C): 09932-78310





Check SDM for DTC.

With ignition switch turned ON, is DTC B1061 or B1065 still indicated?
YES -
Go to Step 3.
NO -
Replace front side-air bag (inflator) module referring to Removal and Installation Front Side-Air Bag (Inflator) Module Removal and Installation:Advanced Air Bag.

3. Front side-air bag circuit check

With ignition switch turned OFF, disconnect special tools from applicable front side-air bag (inflator) connector "Q104" or "Q105".
Disconnect SDM connector "L04".
Check for proper connection to SDM connector at terminal "L04-11" and "L04-12" (for DTC B1061) or terminal "L04-13" and "L04-14" (for DTC B1065).
If OK, release shorting bar in SDM connector inserting release tool (1) included in special tool (A).
Special Tool

(A): 09932-76010

Measure resistance between "L04-12" and "Q105-1" terminals, between "L04-11" and "Q105-2" terminals (for DTC B1061).
Measure resistance between "L04-13" and "Q104-1" terminals, between "L04-14" and "Q104-2" terminals (for DTC B1065).






Is each measured resistance 1ohms or less?
YES -
Substitute a known-good SDM and recheck.
NO -
Go to Step 4.

4. Floor harness circuit check

Disconnect applicable "L384" or "L385" connector under front cushion.
Check for proper connection to floor harness connector at terminal "L385-1" and "L385-2" (for DTC B1061) or terminal "L384-1" and "L384-2" (for DTC B1065).
If OK, release shorting bar in SDM connector inserting release tool (1) included in special tool (A).
Special Tool

(A): 09932-76010

Measure resistance between "L04-12" and "L385-1" terminals, between "L04-11" and "L385-2" terminals (for DTC B1061).
Measure resistance between "L04-13" and "L384-1" terminals, between "L04-14" and "L384-2" terminals (for DTC B1065).






Is each measured resistance 1ohms or less?
YES -
DTC B1061: Repair high resistance or open wire in "YEL" or "BLK" circuit at driver-side front side-air bag harness.
DTC B1065: Repair high resistance or open wire in "YEL" or "BLK" circuit at passenger-side front side-air bag harness.
NO -
DTC B1061: Repair high resistance or open wire in "GRY/RED" or "GRY" circuit at floor harness.
DTC B1065: Repair high resistance or open wire in "BRN/WHT" or "BRN" circuit at floor harness.

NOTE:

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 referring to DTC Clearance DTC Clearance:Advanced Air Bag
, if any.
- Repeat Air Bag Diagnostic System Check Air Bag Diagnostic System Check:Advanced Air Bag
to confirm that the trouble has been corrected.
