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
