Autel Maxicheck Pro
Foxwell NT630 Elite
Vident iLink400 GM scannerGM MDI clone
GM Tech II
In details… Top 1. Here’s a guy doing the GM ABS bleed procedure on an Autel Maxicheck Pro, $179.
Top 2. Foxwell NT630 Elite is about $189 and seems like it will perform the automated ABS bleed feature.
So far this Foxwell is the cheapest I’ve found. Got a reply to my question on chinaobd2.com from Foxwell NT630 and they say this can do it on my 96 Tahoe. Think I’m holding out for a Tech 2 though.
Top 3. Vident iLink400 GM scanner is also able to do ABS bleeding.
Read Vident iLink400 GM function list:
https://www.chinaobd2.com/upload/pro/19102615720743541414.zip
There are 2 tables, one is ” funtion list” and another one is ” special function”, search “ABS” in the table of ” special function”. And this table is not the newest, if you can’t find your car model, you can contact at email Sales@CHINAOBD2.com.
Top 4. This guy used a GM MDI clone, which I believe is cheaper than a tech2 knock-off. The video comments says it can do the crank relearn and ABS bleed.
Top 5. GM Tech 2 is tested working fine to bleed the ABS.
Bleeding ABS on Corvette with GM Tech II by following the next procedure.
Perform a manual or pressure bleeding procedure. If the desired brake pedal height results are not achieved, perform the automated bleed procedure below.
The procedure cycles the system valves and runs the pump in order to purge the air from the secondary circuits normally closed off during normal base brake operation and bleeding. The automated bleed procedure is recommended when air ingestion is suspected in the secondary circuits, or when the BPMV has been replaced.
Automated Bleed Procedure
Notice: The Auto Bleed Procedure may be terminated at any time during the process by pressing the EXIT button. No further Scan Tool prompts pertaining to the Auto Bleed procedure will be given. After exiting the bleed procedure, relieve bleed pressure and disconnect bleed equipment per manufacturer’s instructions. Failure to properly relieve pressure may result in spilled brake fluid causing damage to components and painted surfaces.
1.Raise the vehicle on a suitable support.
2.Remove all four tire and wheel assemblies.
3.Inspect the brake system for leaks and visual damage. Refer to Brake Fluid Loss or Symptoms – Hydraulic Brakes. Repair or replace as needed.
4.Inspect the battery state of charge.
5.Install a scan tool.
6.Turn ON the ignition, with the engine OFF.
7.With the scan tool, establish communications with the EBCM. Select Special Functions. Select Automated Bleed from the Special Functions menu.
8.Bleed the base brake system.
9.Follow the scan tool directions until the desired brake pedal height is achieved.
10.If the bleed procedure is aborted, a malfunction exists. Perform the following steps before resuming the bleed procedure:
– If a DTC is detected, refer to Diagnostic Trouble Code
(DTC) List and diagnose the appropriate DTC.
– If the brake pedal feels spongy, perform the conventional brake bleed procedure again.
11.When the desired pedal height is achieved, press the brake pedal in order to inspect for firmness.
12.Remove the scan tool.
13.Install the tire and wheel assemblies.
14.Inspect the brake fluid level.
15.Road test the vehicle while inspecting that the pedal remains high and firm.
I’d like to say: The tech2 clones work perfectly fine, they will do ANYTHING a original $3000 one will do, the only notable difference is the built in power module will not hold up to a low voltage vehicle restart, so the workaround is to simply plug in a 12v dc power adapter to a extension cord, there are very few instances where you would even need to do that. otherwise they are well worth the investment, just getting a diagnostic from the dealer is around $125 a pop, you can stay at home and save time and money.
