Mustang ABS Repair

When we obtained the Mustang, he ABS light was on. We needed to fix it to pass inspection. 

An auto shop pulled the codes and surprisingly it was the ABS Control module and not the wheel speed sensors. We decided to try to fix it ourselves.

Sara ordered a replacement part, Doug borrowed a jack and stands from Johns S. and the fun began ... 

Step 1: remove old ABS control module

Steps 2 & 3: uninstall faulty control module and swap parts to make one working unit

Steps 4 & 5: reinstall module, fill brake fluid, bleed brakes

As with any project the predicted time was doubled and maybe tripled. The drama:

• Day 1 (hour 1): uninstall the broken control unit. Build DIY plugs to prevent brake fluid from leaking all over the place.
• Day 1 (hours 2-3): struggle to seat the brake line fitting. Connection didn't seem great. Turn on car, ABS light was no longer on, but brakes were out due to no brake fluid.
• Day 2 (11:00am): poured break fluid into reservoir, lifted back of car to bleed brakes. Nothing came out ... because all brake fluid leaked out of faulty connection.
• Day 2 (12:00pm): went to Advance Auto Parts to purchase brake line to test whether the brake line or the housing was to blame.
• Day 2 (1:00pm): uninstall 'new' ABS control unit
• Day 2 (2:00pm): remove electronics from new ABS unit and install in old unit
• Day 2 (3:00pm): reinstall old ABS control unit with new electronics, bleed rear breaks (RJ pushed the brake pedal while I controlled the bleeder valve), run out of brake fluid
• Day 2 (4:00pm): return to Advance Auto - return brake lines, purchase additional brake fluid, bleed front brakes.
• Day 2 (5:00pm): say a prayer ... turn the key ... no ABS light! No brake light! Whew!

Initial time estimate: 4 hours

Actual time: 9 hours (3 trips to Advance Auto Parts)
