Error code 74?

[Aryan15]

I recently did the KOER test on my 89 2.3L, and got a code 74(brake switch on/off during dynamic). Can anyone explain what this means? How do I fix it? Thanks

Looked at www.fuelinjection.com/index.php?p=47. It said code 74 quote "Brake on/offswitchnot activated during KOER test(user error)". Looked on wiring diagram brake on-off switch goes to pin # 2 at computer. Maybe check switch or wiring. Diagram at Autozone.com or elsewhere on line. That is where I got mine. Hope this helps
