Automated Test

The Automated Test cycles each valve solenoid and the pump motor (as well as the necessary relays) to check component operation. This test is identical to the INITIALIZATION SEQUENCE. If a malfunction is detected, the Electronic Brake/Traction Control Module (EBTCM) will set DTCs, which will be displayed upon completion of the test.
