P0617

Starter Relay A Circuit High

Starting system Generic OBD-II High

What it means

P0617 means the ECM detected high voltage on the starter relay control circuit. Because this relay energises the starter, a fault here can cause a no-crank or no-start condition. It is most often a bad relay or a wiring problem, with the ECM being the least likely cause.

Can I keep driving? May not crank or start — if the engine won't turn over, don't keep trying; get the starter relay circuit checked.

Common symptoms

What you'll notice

Common causes

Most likely first

  1. Faulty starter relay
  2. Corroded, open, or short-to-voltage wiring in the relay control circuit
  3. Poor connection at the relay socket or ground
  4. Failed engine control module (ECM), least likely

How to diagnose & fix

Work through it in order

  1. Read freeze-frame data and confirm the relay control circuit reads high.
  2. Swap or bench-test the starter relay to rule it out (often interchangeable with another relay).
  3. Inspect the relay control wiring and connector for corrosion, opens, or a short to voltage.
  4. Verify the ECM is grounding the relay control circuit when start is commanded.
  5. Repair the wiring or replace the relay, then re-test starting.

FAQ

Quick answers

Is it safe to drive with P0617?+
The concern here is starting, not driving. If the engine does start, it will run, but you risk a no-crank the next time. Fix the relay circuit before you get stranded.
Can I just clear P0617?+
Clearing won't help if the relay or wiring is faulty — the code returns and you may face a no-start. Repair the circuit first.
