anyone know what the identifier would be to see if a 2006 HHR/LT has ABS brakes or not(either front only or all wheel) on the service identifier sticker in th glove box...there's lots of codes and i would imagine that one denotes ABS for the vehicle??

 

I found an old thread that says it JM4...

 

Here is the RPO code list, the meaning of the code doesn't change.

The easy way would be to look under the hood for the big "black box" with all of the brake lines on it. ABS was all or none. Or, look at the back of your hubs for electrical wires for the wheel speed sensors.

 

Yes, JM4 , ABS front disc, rear drum brakes
