Default Re: Yellow RJ45 Connector & 4 way power connector

Lets work on the rest.. in green text

1. Ignition key on the ?OFF? or ?0? position:
- Dash Gauge is plugged in and switched on.
- All the RJ45 plugged are colour matched.
- 4-way plug is engaged into the socket.
- No leds should be lit anywhere.

PASS

2. Ignition key on the ?ACC? or ?#1? position:
Absolutely no change, same as the above conditions.

PASS

3. Ignition key on the ?pre-cranking? or ?#2? position:
- Do not crank. Observe the gauge and controller leds
- Yellow led on the gauge will stay lit for 5-10s before
the rest of the gauge lights up.

PASS

- ?S? and ?W.INJ? led should be lit on the gauge.

PASS


- All the green leds on the HFS-6 controller should be
lit with the exception of the green connector.
FAIL. RED CONNECTOR, F-IDC, THRES NOT LIT
Richard: This statement is referring to the green leds on the RJ connectors. Not the red led on the controller board.
Update: The green led on the read harness on newer HFS-6 moitors the flow sensor's turbine movement.



3. Start the engine and let it idle for a minute or so:
- The green led on the controller should flicker
FAIL. RED CONNECTOR, F-IDC, THRES NOT LIT AND NONE FLICKER
Richard: Not until the green wire is detecting the fuel injector IDC properly, it will not flicker. Tell me how go went about connecting this wire to the fuel injector (-).

- The yellow led on the ?green? and ?yellow? RJ Connector
socket should flicker.
FAIL. LIGHTS ON , BUT NO FLICKER
Only the yellow led should flicker, green should be solid. This is further proof that the IDC is not read properly is th eyellow led doesnot lit up of flicker. Test the green wire of the yellow RJ connector by grounding it momentarily. You should see those two yellow leds light up.

- Flicker should speed up with engine speed.
FAIL. LIGHTS ON , BUT NO FLICKER
The green led on the yellow RJ conenctor socket should be a solid green.
