Brake Booster Motor B Phase U-V-W Current High

Check these first

• Excessive current draw in brake booster motor B phase U, V or W
• A short between motor B phase windings
• A binding motor B adding mechanical drag and current
• A short to ground in a motor B phase wire
• A failed phase driver in the brake booster control

What to do next

1. Check the brake booster motor B connector for damage
2. Measure resistance between motor B phase pairs
3. Test each motor B phase wire for a short to ground
4. Check the motor B for binding or mechanical drag
5. Replace the brake booster motor if a phase is shorted or binding
6. Clear the code and retest
