'Service Suspension System', 2010 Yukon Denali

[Doubeleive]

For that price, they're OTW Thanks. Will plugging them in instead of the shocks keep the ALS from working?...Thinking after writing, I guess it should not, since the ride height sensors are on the rods. The plugs on the shocks are just to tell the system they're there, I suppose...
Here's the shocks I ordered. They're a direct replacement for what I had; my oem part number is right on the list !?!?

ya for $83 those are pretty much guaranteed to be passive only, I would bet money if you connected a meter to that connector on the shock it will show a open circuit

 

[j91z28d1]

so they are working airbags but passive shocks. huh.

you said the light went out and alls well? I can only guess the connector is on the shock has a resistor in it to trick the mag ride. not a bad idea if so, saves buying external resistors.

do you still have the mag ride shocks up front?

my bet is those connectors are just there to hold the wire and do nothing otherwise, hence the service suspension error, or if they do have resistors built in there garbage resistors.

I very well could have misunderstood. if he's still getting codes. you're probably right.


I know money is tight for everyone, but the oem shocks that keep the mag ride are the best option. shame they are so expensive

Yes I’m still getting the msg. I measured 4.3-4.4ohm across one of them, so the appears to be something there. What info would that device give back, other than ‘the shock is there’?
I bought these cheaply, mostly to test the system and see if everything worked once the bags could hold air. Obviously, they raise as many questions as they answer!

Did you measure resistance on both shocks?

3.9 Ohm 25 Watt is what is needed, I would think 4.3 is fine, check both shocks to verify they are both reading the same.

BTW
A 3157 turn signal bulb has the right resistance to fool the module. You can use them to be sure the signal to the shocks is present. If the trouble code goes away one of the shocks is bad.

This would be easier to diagnose with a scan tool like a Tech2.

Here is a good thread on this.

Autoride suspension help

I have a 2009 Yukon Denali Xl. For the past few months the Autoride compressor has been super noisy and running constantly. 2 weeks ago, I decided to replace the rear shocks with Arnott rebuilt units. After replacing the compressor was still noisy which is knew it would be, but it would run as...

Do you mean a 3157?
