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.

DTC B1032: Driver Air Bag Circuit Low ResistanceS6RW0D8204019
Wiring Diagram
Refer to “DTC B1031: Driver Air Bag Circuit High Resistance”.
DTC Detecting Condition and Trouble Area4Floor harness circuit check
1) Disconnect “L378” connector located near the driver side
front pillar lower trim.
2) Check for proper connection to floor harness connector
at terminal in “L378” connector.
3) If OK, release shorting bar in SDM connector inserting
release tool (1) included in special tool (A).
Special tool
(A): 09932–76010
4) Measure resistance between “L04-3” and “L378-1”
terminals.
5) Measure resistance between “L04-4” and “L378-2”
terminals.
Is each measured resistance 1
Ω or less?Repair high resistance
or open wire in “GRN/
RED” or “GRN” circuit at
instrument panel
harness.Repair high resistance
or open wire in “GRN/
RED” or “GRN” circuit at
floor harness.
5Contact coil circuit check
1) Check contact coil circuit referring to “Contact Coil Cable
and Its Circuit Check”.
Is contact coil circuit in good condition?Replace driver air bag
(inflator) module
referring to “Driver Air
Bag (Inflator) Module
Removal and
Installation”.Replace contact coil
