Check for proper connection to SDM connector at terminal "L04-11" and "L04-12" (for DTC B1062) or terminal "L04-13" and "L04-14" (for DTC B1066).
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 "L04-11" and "L04-12" terminals (for DTC B1062) or between "L04-13" and "L04-14" terminals (for DTC B1066).






Is each measured resistance infinity?
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 applicable floor harness connector at terminal in connector "L384" or "L385".
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 "L04-11" and "L04-12" terminals (for DTC B1062) or between "L04-13" and "L04-14" terminals (for DTC B1066).






Is each measured resistance infinity?
YES
DTC B1062: Repair "YEL" circuit for short to "BLK" circuit at driver-side front side-air bag harness.
DTC B1066: Repair "YEL" circuit for short to "BLK" circuit at passenger-side front side-air bag harness.
NO
