Failsafe with HKS EVC 6

[P997.tt]

Update:

Found a cut in the path of the molex red, repaired and reassured connection to A8 ...

Water level light is Finally OFF!!!!!!! Happy day!

Confirmed by jumping the pump with the sys link ...

Niw the green led still didn't come one, and the thres amber is not coming on now too ... I tried the test idc jumper and the S led does flicker with throttle ..

first step is a success!

now the iDC signal.

I am afraid you have to retest all the test points again. This time, with the engine running.

Can you post a hi-res picture of the top side of the controller.

Post light fix diagnostic readout, Engine running idle:

Hi Richard, awaiting your input on the readings above, here is the picture you requested:

[P997.tt]

Took the car for a spin and its not acting right.

With the system of I get no boost at all, with it on only about 3-4psi and some flow bars before both yellow led's come on ... Think its in failsafe mode ... Is this due to the idc issue too?

For the time being, disable the failsafe by linking the "DFS" with "PRK"

Thanks for the update, it appears the test points are is now reading correctly. The controller is OK on all the basic functions.

Moving onto the next diagnostic work:

A few question first to help me:
1. When you do the SYS test, does the red and yellow led comes on on the controller.
2. SYS test: Did the system spray?
3. SYS test: Did the gauge show flow?

Next test for the green led:
4. Unplug the red and blue harness to stop the pump and FAV from activating.
5. Unplug the green harness.
6. Ground the green wire of the ECU harness (grey) and tell me if you all the leds come on on the controller.

Await your reply.

Link the "DSF" with "PRK" to disable the failsafe for the time being.

I went back in and disconnected the failsafe manually for now, if all goes well will deal with that, will test it later tonight if it boosts again ..

Answers:
1-yes both amber and red came on with the sys test
2- i disconnected the fav to purge the line and it did deliver to that end didnt test the jet end though, but the road test earlier it did show a few bars before fs kicked in ..

I did the ground test before when the system was malfunctioning and the green light sid not come on ...

Will try again and update

Richard,

Same result, when I grounded the green wire the amber and red lights came on, no green ..

What is causing the failsafe to kick in? System is receiving the idc signal clear from the voltage readings. Could it be triggered by an unsecured fav In the engine bay?
