For the GReddy TT install, Greddy has us taping into the ECU power wire, pin # 119, for powering the e-manage.

The wire I tapped into for this, I also use it for the PRofec e-01
power.
Been running like this since January.

I just added a fuel pressure gauge, and wideband 02, and used this same wire to tap off of for power, and now this ECU wire (pin 119) is no longer getting power.

Sounds like I might of blown a fuse. Checking fuses, I can't find any blown.

Does anyone know where I should check on power source for the ECU ?

Thanks in advance

 

Did you check EC-400 in the service manual? Might have some info there, I'm looking now.

 

thanks for the reply, pg 400 seems to be where I need to look.

I removed all the power I had coming off the ECU power now, except for the e-manage, like GReddy has diagramed.

Now I just have to figure out how to get power back to it...

 

Which fuse block are you checking? There are at least three that I am aware of. Behind left drivers kick panel, in front of battery, and the one I just discovered the other day, a third behind and to the left of the battery. To get to this one, you need to take off the battery cover

 

ECU pin 119 is connected to Joint Connector-4, which then is connected in parallel to ECU pin 120 (later down the line)..

check the Intelligent Power Distribution Module Engine Room (RPDM E/R) there is a Relay inside...

as for checking ECM power, check the voltage at 119 and 120.. if that doesnt give any power, check 111

there is a 15Amp fuse from the IPDM E/R.. it is located next to the battery in the engine compartment.. there is a Cover, which you need to pop off... check fuses there... this is on page PG-27 of the svc manual...
