Refer to the scan tool manual for complete scan tool operating instructions.

Automated Bleed

--

The EBCM commands each valve solenoid and the pump motor ON and OFF in a special sequence in order to bleed air out of the brake pressure modulator valve (BPMV). Refer to Antilock Brake System Automated Bleed Procedure for a step-by-step procedure.

ABS Motor

--

This function allows the technician to command the ABS pump motor ON and OFF.

Tire Size Calibration

Important: The powertrain control module (PCM) must also be programmed with the correct tire size calibration when different size tires are installed on the vehicle. Refer to Service Programming System (SPS) in Programming and Setup.

This function allows the technician to read the tire size calibration of the EBCM or calibrate the EBCM to the correct tire size. Calibration must be performed when the EBCM is replaced or when different size tires are installed on the vehicle.

Solenoid Tests

This function allows the technician to command a selected valve solenoid ON and OFF. Use the procedure below in order to verify proper operation of the EBCM and BPMV.

Solenoid Test Procedure

1. Raise the vehicle so the wheels are about 15 cm (6 in) off the floor. Refer to Lifting and Jacking the Vehicle in General Information.
2. Select the desired Solenoid Test on the scan tool.

Important: Steps 3, 4 and 5 must be performed within a 5-second time period. The EBCM will only energize a solenoid for 5 seconds.

3. Command the solenoid ON.
4. Apply the brake.
5. Have an assistant attempt to spin the wheel of the brake circuit being tested. The wheel should spin even though the brake is being applied.
