| Red 2001 Hyundai Accent Rear View |
I have a 2001 Hyundai Accent
GL 1.6L DOHC Auto. If The Overdrive button is not engaged when I start
the car it blows the ECU/TCU fuse as soon as I turn the key.
If I am driving with the overdrive on and It gets turned of the fuse
blows and the car quits. When this happens all I have to do is engage
the OD and then replace the fuse and its fine. This is a real pain in the butt. Nothing has been altered or “fixed” electrically. Its all factory and stock. Its a 10amp 2 prong fuse. I cant figure out what would cause this. Any help would be great thanks.
Answer: Hyundai’s
have extremely poor wiring. The factory actually stretch the wires used
in the looms so as to get more wiring looms from a roll of wire
(strange I know but this came directly from a person at Hyundai). I once
had a 96 Sonata that would blow the main power fuse only if the
headlights were on high beam and you placed the trans in reverse.
Problem was the owner had a very long and dark driveway. After chasing
the problem for a week we finally found the loom had a break in a single
wire (which had been stretched) causing feedback and ultimately a dead
short in the main power circuit. It is possible that your solution may be as simple as a bad overdrive switch but I wouldn’t bet on it.
