Code A015 - Enable Relay Contacts Shorted To Battery: Notes

1993 Chevrolet Camaro Z28, Standard, M29SECTION Notes

Ignition voltage is supplied through terminal C2 of ABS enable relay. EBCM energizes pull-in coil by completing ground circuit at pin B3 of EBCM. Magnetic field created will close enable relay contacts to supply battery voltage to Electro-Mechanical Brake (EMB) and EBCM, providing power to motors and solenoids.

This test determines if enable relay is energized when required. Fault Code A015 prevents enable relay from removing power from ABS system. If a second fault occurs and turns enable relay off, fault cannot be removed if relay cannot be controlled. Code A015 will set after 3 drive cycles. Once Code A015 is set, ABS INOP light will flash to indicate malfunction, but ABS system will not be disabled.

NOTE: Test numbers refer to numbers on diagnostic chart.
  1. This step determines if EBCM is capable of controlling enable relay.
  2. This step checks for short to battery in circuit No. 1633 (Red wire).
  3. This step checks if circuit No. 1632 (Pink wire) is shorted to ground.
  4. This step determines if short to battery is in circuit No. 1633 (Red wire) or EBCM.
  5. This step checks for intermittents in wiring or connectors.

  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
