2014年5月5日 · Looks right to me. If you want to verify visually, take a look at the brake lines where they hop over the center of the rear axle. If there are 2 flexible lines, you are JL4. Otherwise, there will only be 1 that splits to the 2 rear calipers.

2024年8月12日 · I have a 2005 Tahoe Z71 4x4 with the stablitrack / JL4 EBCM module. We replaced the module due to no communication with the scan tool. We had success with a JL4 module from an 05 Escalade, and have a line of communication with the scantool to perform bidirectional diagnostic and testing.

2019年5月25日 · Now in my searching JL4 is stabletrack G80 is positraction and GT5 is 4:10 gears . Now when searching this was only one found in the 2006 I bought. I noticed some years did not include positraction with stabletrack .. but 2006 did was there something different with the transfer case or does stabletrack just not kick in untill out side 20 mpg ...

2020年7月2日 · I have a 2005 Yukon XL 1500 Denali. I had a brake line rust out, and accidentally stripped out the threads on the ABS module attempting to run new brake lines to the rear. I have the JL4 RPO code. My understanding is that the exact ABS module for this particular build spec was only used for a couple of years and is hard to find a replacement for.

2022年3月15日 · Hey new this forum . Just purchased a 05 Yukon xl Denali 6.0 AWD with active brake control. The vehicle locks brakes after around 5 min into driving . The car was from Nebraska not sure if that makes a difference and I’m in socal. Some say could be my brake lines and hoses and some say my wheel...

2024年10月5日 · I have an 2004 Gmc Yukon xl with code JL4 stabilitrak(?) I had a line blow out from the brake port to I thinkbthe Abs Modulator and cant seen to locate a repalcement line. Looked at parts at Autozone Advanced and Amazon. I additional bought a new brake line kit from Doorman # 919-149 not...

2018年11月2日 · JL4 in the glove box. 6 flexible brake lines vs. 5. If you have 2 over the rear axle instead of 1, you have JL4. Reactions: kbuskill , Jolly Roger and wjburken

2023年2月9日 · Only the JL4 trucks came this way, and apparently from my research you cant find new pumps either, just the regular abs pump. Reactions: Sam Harris , swathdiver , OR VietVet and 1 other person Feb 9, 2023

2018年3月23日 · The only difference I can see in the one's O'Reilly sells (have commercial acct) is that it wants to know hydroboost or vacuum, and then if it has JL4 active brake control. If you have a traction control switch then you don't have active brake control, if you don't have the switch then you do have active brake control (JL4 code in glove box).

2014年5月5日 · Yes you can. The abs pump can get air in it but if you cycle the key before each caliper it should bleed fine, if not you can bleed, go for a ride and fine some grass or gravel and lock em up then bleed again, etc etc. make sure you don’t floor the pedal when pumping, you’ll blow seals in master.
