VodkaMan 10-05-2002, 01:33 PM I have a 95 Disco that is reading #48 fault code. I saw at disco web a #48 fault code for a 4.0 is listed as "stepper motor". my question is are the codes the same for 4.0 Discoverys and 3.9 Discoverys? If they are the same what is a "stepper motor"? Puffdragon 10-05-2002, 02:43 PM A stepper motor controls the idle system. on a 3.9, it is on the back passenger side of the plenum. VodkaMan 10-05-2002, 03:22 PM Thanks Puff so the fault codes will be teh same on both motors? Puffdragon 10-05-2002, 04:58 PM cant remember if they are the same, I am not used to dealling with regular codes. I always used Test book, which gave a description of the fault, so I never had to look up a code number. And I never check the codes on my D-90, I just clear the comp., and see if it comes back, and they never do. K.C. carpenter | |
