i always do a complete brake job all the hoses, calipers, wheel cylinders, pads, shoes, drums, rotors, and flush the snot out of it. it cost a little more but it is worth it.

I have an '89 Dakota with the "Maintenance Required" light on. One book says DRB 2 and I see OBD 2 tools mentioned. How can I clear it? Which tool will connect? I assume the blue box reset won't work on my '89. Local dealer was not much help.

DRB 2 or something equivalent.

OTOH, you CAN just unplug the blue box if you have it ... that way, it'll go out. Or take the bulb out.

It only says "Times to check EGR system"; that's all.

I can't locate the connector, I don't know what it looks like. Does it need to be DRB 2 or will OBD 2 work? Any one have a Dodge service manual for an '89? Thanks in advance. Doug.

http://www.autobooksbishko.com/searc...k&category=All shows the disc version for under $40 as I type this.

No, it's not OBDII. DRB2 is the version of the dealer tool.

The connector is under the hood, by the blower motor resistor, under the coil and a bit towards the passenger side. It looks like this:

Here's what will plug into it





My SnapOn 2500 with the right carts and adapter will work just peachy keen. You may want to find one used on fleaBay and see what you can get it for.

Also, easiest thing to do is to remove the blue box (towards the door from the knee blocker under the dash; the one near the fuse box) if your truck uses it. If it's in the ECU, either a DRB or something similar to reset it, or just remove the light.

Thanks much. I'll look around for the plug in. I may just try to unhook the light. The chassis manual is a good idea.
