Ford 111 System pass

How to read it

Code 111 reads as 1 flash, pause, 1 flash, pause, 1 flash on the check-engine light. Jumper the self-test input to signal return at the test connector, then run the key on engine off self test and the running self test, counting the check-engine flashes each time.

What does Ford code 111 mean?

System pass

What this result tells you

• Both the KOEO and KOER self tests finished with no faults stored.
• All sensor and actuator circuits stayed within range through the test.
• A fresh repair cleared the memory and the system now passes.
• A battery disconnect wiped the keep alive memory ahead of the test.
• The fault is not present at the moment the test runs.

What to do next

1. Read code 111 as a clean pass, not a stored fault, so no parts are due on its account.
2. Keep reading the flash sequence and address any code that follows it.
3. Road test and retest when a driveability symptom points to an intermittent fault.
4. Repeat the test under the same conditions that set the symptom before declaring the system healthy.
5. Retest once more after any repair to confirm the pass still holds.
