Injector Malfunction ### of individual coil?

[4g63telantra]

I just started tuning the car with a friend of mine. We almost got the car running better till code 0041 Injector Circut Malfunction came on with DSMLINK.

Can this code be from running individual coil park? (4 MSD blaster SS)

Has anyone got this code before?

Thanks

A code 41 means that the ECU lost 12v at one of the injector pins. It expects that after it fires the injector the voltage will settle back to battery voltage and if it doesn't it throws an error.

Ignition problems throw different codes.

What can this code mean? wiring problem? bad ECU?

It means that somewhere in the injector circuit it broke.
It could be a loose connector, broken wire, bad injector, or bad injector resistor.

Start at the ECU with the ignition on and check each of the 4 injector pins for battery voltage. Hopefully you have a hard failure so you'll find one of the pins doesn't have power and can then trace it back to the problem.
