Abs Quick Check Chart
NOTE:
For measurements, use Breakout Box (014-00322), Overlay (007-00103), ABS Adapter (T93T-50-ALA) or equivalent.
Ensure resistance exists between breakout box pin No. 1 and ground, or invalid results may occur. Incorrect results indicate wiring or component failure. See appropriate test for complete diagnostic procedures before replacing component. Go to TROUBLE CODE TESTS or SYMPTOM TESTS .
When testing wheel speed sensor output, measure frequency and voltage. Result of voltage divided by frequency will not change with wheel speed. Take both measurements at same wheel speed. If ABS quick check is okay, go to DRIVE TEST .
