A/C Clutch Current Fault
The A/C clutch current is outside the expected range.
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 A/C system isn't pulling the right amount of current to engage the clutch, which can prevent the A/C from working properly.
What the computer is actually seeing
The engine control module (ECM) expects a specific current draw from the A/C clutch, around 2-3 amps when operating correctly. If it sees less than 1 amp or more than 5 amps, it throws this code.
What a healthy reading looks like
A/C clutch current should be around 2-3 amps.
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 A/C fuse and relay integrity (replace if blown). Decision: Good or bad? If bad, replace and retest.
- 2Inspect wiring and connectors for damage or corrosion. Decision: Any issues found? If yes, repair or replace as needed and retest.
- 3Check the refrigerant level in the system. Decision: Is it low? If yes, recharge and retest.
- 4Using a multimeter, measure the A/C clutch current when A/C is on. Decision: Is it within 2-3 amps? If no, continue to next step.
- 5If the current is out of range, isolate the A/C clutch. Measure resistance across the clutch. Decision: Is it within normal resistance specs? If no, replace the A/C clutch.
Common causes
- Wiring issue in the A/C circuit
- Faulty A/C clutch or compressor
- Bad A/C relay
- Low refrigerant level
- Corroded connectors
