Hi, I am Mike, welcome. I'm reviewing your question.
I believe the next step would be to retrieve the trouble codes to see which may refer to this problem because the pcm relies on a sensor to control that module and turn on the fans.
Perform this PINPOINT TEST KN
Skip that test then. Or go to radio shack or somewhere and get a 1.6 ohm resistor.
Yes, it said "PCM connector disconnected"
1 what? ohm? if you zero the meter first then try again.
Even so if the reading is less than 10k ohms, that's 10,000 ohms, "REPAIR the short circuit. CLEAR the DTCs. REPEAT the self-test." That was test KN6, correct?
So you meant 1 volt?
Why would you be jumping your multimeter leads together when on dc volts?
You got me confused now. You said you were checking resistance, that's step kn6, then you say kn5, that was the voltage test.
Ok, no voltage at kn5 is less than 1 volt. and the answer to kn6 is less than 10,000 ohms, so REPAIR the short circuit. CLEAR the DTCs. REPEAT the self-test
Let's back up here, at first you said 1, which I assumed meant 1 ohm, then you said no resistance. What did you mean by no resistance? zero? or infinity such as an open?
If you meant zero, then that white/blue wire is shorted to ground. That is what I interpret from that.
Did that answer your question? If so, kindly leave me a positive rating, so I get credit. After all, you have already made the deposit.
