DIAGNOSTIC FLOW TABLE
DTC B1031 :
Fig. for STEP 1
Special tool
(A) : 09932-75020
DTC B1032 :Step Action Yes No
1 1) With ignition switch OFF, disconnect SDM
connector.
2) Check proper connection to SDM at “Q01-4”
terminal.
3) If OK then ignition switch ON, and then
check voltage from “Q01-4” terminal on
SDM connector to body ground.
Is voltage 14 V or less?Go to step 2. Check Charging System
and repair as necessary.
(Refer to DIAGNOSIS in
Section 6H)
2 1) With ignition switch OFF, reconnect SDM
connector.
With ignition switch ON, is DTC B1031 current?Substitute a known-good
SDM and recheck.Check Charging System
and repair as necessary.
(Refer to DIAGNOSIS in
Section 6H)
NOTE:
Upon completion of inspection and repair work, perform following items.
Reconnect all air bag system components, ensure all components are properly mounted.
Clear diagnostic trouble codes (Refer to DTC CLEARANCE), if any.
Repeat AIR BAG DIAGNOSTIC SYSTEM CHECK to confirm that the trouble has been corrected.
Step Action Yes No
1 1) Measure voltage on battery.
Is voltage 11 V or more?Go to step 2. Check Charging System
and repair as necessary.
(Refer to DIAGNOSIS in
Section 6H)
2 1) With ignition switch OFF, disconnect SDM
connector.
2) Check proper connection to SDM at “Q01-4”
terminal.
3) If OK then ignition switch ON, and then
check voltage from “Q01-4” terminal on
SDM connector to body ground.
Is voltage 8 V or more?Go to step 3. Possibly faulty points are
as follows. Check each of
them and repair as neces-
sary.
•Circuit from battery to
“Q01” connector
•Charging System
