2020 Hyundai Ioniq - Intermittent Rear Right EPB "Open Circuit"
Hey everyone,
I’m having a frustrating issue with the Electronic Parking Brake (EPB) on my 2020 Hyundai Ioniq.
The diagnostic scanner is throwing a code for an "Open Circuit" on the rear right EPB actuator.
Here is the catch: the issue is intermittent.
Sometimes the error disappears on its own, and both parking brakes work completely fine.
A short while later, the warning light comes back on.
What I've checked so far:
I inspected the wiring harness going to the rear right caliper. I wiggled and twisted the cables to see if I could trigger/fix the fault or find a visible break, but visually, everything looks intact and I couldn't find any obvious damage.
