Voltage Supply Circuit Fault
There's a problem with the voltage supply circuit for the actuator.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The actuator isn't getting the right voltage, which can mess with its operation. This can lead to performance issues, like poor acceleration or increased emissions.
What the computer is actually seeing
The computer monitors the voltage supply circuit for range between 0 to 5 volts for correct operation. If it sees a voltage drop below 0.5V or above 4.5V, it triggers this code.
What a healthy reading looks like
Should see 0.5V to 4.5V for normal operation; under 0.5V indicates a fault, while over 4.5V indicates an overvoltage condition.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check the wiring and connectors for the actuator for damage or corrosion.
- 2Using a multimeter, test the voltage at the actuator connector. It should read between 0.5V and 4.5V.
- 3If the voltage is low, backtrack to check for shorts or opens in the wiring harness.
- 4If the voltage is normal but the issue persists, replace the actuator and retest.
- 5If replacing the actuator does not resolve the code, consider further diagnosing the control module.
Common causes
- Damaged wiring or connectors in the voltage supply circuit
- Faulty actuator
- Short circuit in wiring to the actuator
- Open circuit in wiring to the actuator

Frequently asked questions
Is it safe to drive with this code?
It's best to fix it soon since performance and emissions can be affected.
Will this code come back after repairs?
If the repair properly addresses the wiring or actuator issue, it shouldn't come back.
Why does this code relate to the actuator?
The actuator needs proper voltage to function; if it doesn't get it, the system flags this code.
