1) With ignition switch OFF, disconnect SDM connector 

“L32”.

2) Check proper connection to SDM at terminals “L32-1” 

and “L32-2” or “L32-3” and “L32-4”.

3) If OK, release shorting bar in SDM connector inserting 

release tool (1) included in special tool (A).

4) Measure resistance between “L32-1” and “L32-2” 

terminals (for DTC B1332) or “L32-3” and “L32-4” 
terminals (for DTC B1336) with connected special tools 
(A), (B) and (C).

Special tool
(A):  09932–76010
(B):  09932–75010
(C):  09932–78310

Is resistance 0.65 

 or more?

Substitute a known-
good SDM and recheck.

DTC B1332: 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 B1336: Repair 
short from “BLK/YEL” 
wire circuit to “BRN/
YEL” wire circuit or from

1) With ignition switch OFF, remove rear side upper trim of 

left or right side and disconnect side curtain-air bag 
(inflator) module connector.

2) Check proper connection to side-air bag (inflator) 

module at terminals in “G18” or “G41” connector.

3) If OK, then connect special tools (A), (B) and (C) to side 

curtain-air bag (inflator) module connector.

Special tool
(A):  09932–76010
(B):  09932–75010
(C):  09932–78310

4) Check SDM DTC.

With ignition switch ON, is DTC B1333 or B1337 still 
indicated?
