2 1) With ignition switch OFF, disconnect “L32” connector located near the glove box.
2) Check proper connection to floor harness connector at terminal “L32-1” and “L32-2”.
3) If OK, then connect special tools (B) and (D) to “L32” connector.
Special tool
(B): 09932–75010
(D): 09932–77320
4) Check SDM DTC.
NOTE
At this time, DTC B1041 ma y be output, but it is
not related to this check.

With ignition switch ON , is DTC B1032 indicated? Go to Step 3. “GRN/RED” circuit
shorted to “GRN” circuit,
“GRN/RED” circuit or
“GRN” circuit shorted to
other circuit in
instrument panel
harness.

3 1) With ignition switch OFF, disconnect SDM connector “L29”.
2) Check proper connection to SDM at terminals “L29-3” and “L29-4”.
3) If OK, release shorting bar in SDM connector inserting
release tool (1) included in special tool (A).
4) Measure resistance between “L29-3” and “L29-4” terminals with connected special tool (B) and (D).

DTC B1033: Driver Air Bag Initiator Circuit Short to GroundS7RS0B8204020
Wiring Diagram
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 harnes s, connector or terminal is found damaged, replace
the wire harness, connector and terminal as an assembly.

DTC Will Set when
The voltage measured at driver air bag initiator ci rcuit is below a specified value for specified time.
Flow Test Description
Step 1: Check whether malfunction is in contact coil and driver air bag (inflator) module or the others.
Step 2: Check driver air bag (inflator) module initiator circuit. (in instrument panel and floor harness)
Step 3: Check driver air bag (inflator) module initiator circuit. (in floor harness)
Step 4: Check whether malfunction is in contact coil or driver air bag (inflator) module.
