Recently installed an Edge Mileage Max on my '02. The check engine light stayed on for two days and then went away today. P PCU 1693 and P ECU 0273 codes showed on the odometer.

Today, first good snow of the year, so I put it in 4 wheel and it doesn't engage. I drove for maybe a mile assuming it would kick in, the light didn't come on or anything. I stopped and looked under the pickup and nothing looked out of order (vacuum lines, etc.).

After I looked under the pickup I called a buddy asking if he knew somethin about these dodges that I didn't, while I was on the phone, the light came on and the 4 wheel drive engaged and worked.

Any advice helps.

Thanks.

Dunno if I have updated my sig since I got rid of the 12v but I drive a 2002, 6spd, 4X4, 112,000 miles, stock except for the Edge Mileage Max.

 

I have heard the check engine lights can get triggered by the Edge products.

As for the 4 wheel drive issue, I would put a gauge on my vac lines and check for 22-25 psi of suck. A leak will surely cause a slow/non activation of the axle disconnect/connect.

I try to cycle mine a few times a year when I am on a dirt road just to keep things familiar...

 

I haven't been able to look at it yet, hunted all weekend.

I drove it about 50 miles and the whole time the 4x4 light kept flickering on and off. I don't know if that might narrow the problem down?

Thanks, I'll check the pressure.

 

Sweet.

How was your time afield?

 

I see you're from Kalispell. I went to the breaks, out of Jordan, got a decent 5 point muley. Got stuck drivin the tacoma since the dodge's 4x4 isn't workin right.

 

Not really, folks are there, though. I get over a few times a year, not as much as I would like too.......

Nice deer, glad you got one! My Toyota always made it home...

Love my Dodge, though.

 

Was ice in the lines to the actuator, 4x4 works fine now
