2003 Land Rover Discovery, 116mi, 4 amigos.


Performed rewire fix years ago and no 3/4 Amigoes since. Recently replaced front hub and ABS sensor scraped the notches in hub and 4 Amigoes came on. So bought new hub and factory installed ABS sensor but 4 Amigoes returned.


Bought a ABS scanner. Says "Erratic right front sensor signal." OBD2 code is P1590. I reset all but 4 Amigoes come right back and stay on. Reset. 4 Amigoes return and wont go away.


Could this be coincidental failing of brake shoes, ECU, or ABS modulator. Could the sensor be dirty or mis-adjusted from factory?


I hate those 4 Amigoes. These are not my amigos at all.

 

We don't want your life story, but a little more info might be a good idea.

 

Will be good to know which scanner you are using. P1590 is not relate to the front sensors only. The reason of the 3 amigo are coming back after reset is because the fault is still permanent. My experience was a bad sensor cable but I was able to ping point it by using a Lynx scanner.

 

I am using scanner:
Autel AL619 AutoLink ABS/Air Bag + OBDII Scan Tool





I am going through in my mind how replacing the front passenger hub + sensor might cause a simultaneous failure somewhere else in the system.

 

4 Amigos are gone for now.


New hub came with sensor pre-installed. Removed the sensor this weekend. The internal ABS pinwheel was full of grease from the parts manufacturer. This caused erratic front signal message given by my Autel AL619. Cleaned the grease out, reinstalled sensor, mounted wheel. No more 4 Amigos. For now...
