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.
Conditions To Clear
To clear Code 34, ignition must be off long enough to ensure 36VLR supply voltage has fully discharged. Once 36VLR is discharged, Diagnostic Energy Reserve Module (DERM) will again check failure conditions upon key on. Only if failure conditions are not present (no failure indicated) will current Code 34 be cleared.
