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.
DTC 26 - Driver-Side Deployment Loop Open: Description
When there is an open in driver inflator module or SIR coil assembly, resistance between DRIVER-SIDE HIGH terminal No. B9 and DRIVER-SIDE LOW terminal B8 increases. This causes a larger voltage drop from DRIVER-SIDE HIGH to DRIVER-SIDE LOW across a resistor inside DERM which connects these 2 terminals. The increase in voltage difference between DRIVER-SIDE HIGH and DRIVER-SIDE low is detected by DERM during CONTINUOUS MONITORING tests and DTC 26 will set.
