Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Diagnostic Aids
An intermittent condition is likely to be caused by a poor connection at driver-side air bag module terminals A or B, SIR coil assembly terminals A or B, SDM terminals No. 2 or 3, or an open in circuit 347 or 348. An intermittent open in SIR coil assembly could also set this DTC. To test for bad SIR coil assembly, clear DTCs, then turn steering wheel back and forth with ignition switch in RUN position. If AIR BAG warning light comes ON and DTC B1026 has set again, SIR coil assembly is probably malfunctioning.
