Air Bag System: 8B-19
CAUTION
!
• Be sure to perform “Air Bag Diagnostic System Check” before starting diagnosis according to flow.
• When measurement of resistance or voltage is required in this flow, use a tester along with a correct
terminal adapter from special tool (Connector test adapter kit).
• When a check for proper connection is required, refer to “Inspection of Intermittent and Poor
Connections”.
• If there is open circuit in the air bag wire harness, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.
DTC Will Set when
The power source voltage to SDM is above an approx. 21 V for specified time.
Flow Test Description
Step 1: Check if voltage applied to SDM is within normal range.
Step 2: Check if DTC B1016 still exists.
DTC Troubleshooting
NOTE
Upon completion of inspection and repair work, perform the following items.
• Reconnect all air bag system components and ensure all components are properly mounted.
• Clear DTCs referring 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) With ignition switch OFF, disconnect SDM connector.
2) Check proper connection to SDM at “L29-27” terminal.
3) If OK, turn ignition switch ON and then check voltage
between “L29-27” terminal on SDM connector and body
ground.

Is voltage 14 V or less?
Go to Step 2. Check charging system
and repair as necessary
referring to “Generator
Test (Overcharged
Battery Check) in
Section 1J”.
2 1) With ignition switch OFF, reconnect SDM connector.
With ignition switch ON, is DTC B1016 indicated?
Substitute a known-
good SDM and recheck.
Intermittent trouble.
Check for intermittent
trouble referring to
“Inspection of
Intermittent and Poor
Connections” If OK,
substitute a known-
good SDM and recheck.
