Check SDM DTC.

With ignition switch ON, is DTC B1362 or B1366 still indicated?
YES -
Go to Step 3.
NO -
Replace side curtain-air bag (inflator) module. Side Curtain-Air Bag (Inflator) Module Removal and Installation

3. With ignition switch OFF, disconnect SDM connector "L32".
Check proper connection to SDM at terminals "L32-1" and "L32-2" or "L32-3" and "L32-4".
If OK, release shorting bar in SDM connector inserting release tool (1) included in special tool (A).
Measure resistance between "L32-1" and "L32-2" terminals (for DTC B1362) or "L32-3" and "L32-4" terminals (for DTC B1366) with connected special tools (A), (B) and (C).
Special Tool

(A): 09932-76010

(B): 09932-75010

(C): 09932-78310





Is resistance 0.65 ohms or more?
YES -
Substitute a known-good SDM and recheck.
NO -
DTC B1362: Repair short from "YEL/GRN" wire circuit to "YEL/BLU" wire circuit or from "YEL/GRN" or "YEL/BLU" wire circuit to other wire circuit.
DTC B1366: Repair short from "BLK/YEL" wire circuit to "BRN/YEL" wire circuit or from "BLK/YEL" or "BRN/YEL" wire circuit to other wire circuit.

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, 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.
