Diagnostic Procedure

  1. Turn ignition on. Using scan tool, select F0: DATA LIST mode. Monitor brake switch status. If scan tool does not indicate brake switch is open, system is currently functioning correctly. See INTERMITTENT OR POOR CONNECTIONS  . If scan tool indicates brake switch is open, go to next step.
  2. While monitoring brake switch on scan tool, apply light pressure on brake pedal. If scan tool indicates brake switch "ON" within one inch (25 mm) of pedal travel, system is currently functioning correctly. See INTERMITTENT OR POOR CONNECTIONS  . If scan tool does not indicate brake switch "ON" within one inch (25 mm) of pedal travel, go to next step.
  3. Apply firm pressure to brake and inspect rear brake lights. If brake lights are illuminated, go to next step. If brake lights are not illuminated, repair open brake switch circuit. See WIRING DIAGRAMS  .
  4. Turn ignition switch to LOCK position. Disconnect 32-pin EBCM harness connector. Turn ignition switch on. With firm pressure applied to brake pedal, measure voltage between ground and 32-pin EBCM harness connector terminal No. 3 (Green/White wire). If voltage is 10 volts or greater, check for poor terminal contact at terminal No. 3 of EBCM. If okay, replace EBCM. If voltage is not 10 volts or greater, repair open Green/White wire.
