Igntion Cycle Count Error
The ignition cycle count detected is out of range for the system.
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 engine control system keeps track of how many times the ignition is turned on and off. If it sees a number that's too high or too low, it triggers this code.
What the computer is actually seeing
The ECM expects a certain range of ignition cycles. For example, if it sees a count that exceeds its limit (say, more than 1000 cycles in a certain time frame), it triggers the code to indicate a discrepancy.
What a healthy reading looks like
Typically, the ignition cycle count should stay within normal limits, around 0 to 1000 cycles per ignition interval.
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 battery voltage, should be between 12.4V and 12.7V with the engine off.
- 2Inspect all related wiring and connectors for damage or corrosion.
- 3Clear the code and run the vehicle to see if it returns immediately, which indicates a real fault.
- 4Use a scan tool to monitor the ignition cycle count in real-time; anomalies indicate the ECM or wiring issue.
Common causes
- Faulty ECM software
- Poor electrical connection
- Voltage spikes in ignition circuit
- Bad battery or poor power supply
Typical repair cost
$100 - $500

Frequently asked questions
Is it safe to drive with this code?
Yes, but address it soon as it may impact performance.
Will the code come back once cleared?
It may, especially if there's an underlying issue.
Why is this code paired with other SPN codes?
Often, multiple issues can stem from the same fault in wiring or ECM problems.
