Refer to the scan tool manual for complete scan tool operating instructions. | ||||||||||||||||||
ABS Motor | -- | This function allows the technician to command the ABS pump motor On and Off. | ||||||||||||||||
Automated Bleed | -- | The electronic brake control module (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. | ||||||||||||||||
Left Front Brake Apply | -- | The EBCM enegizes the appropriate solenoids and the precharge pump motor to apply brake pressure to the left, front wheel. The precharge pump turns off after approximately 2 seconds, but the brake pressure is held for approximately 9 seconds. Refer to Brake Pressure Modulator Valve Hydraulic Testing for a step-by-step procedure. | ||||||||||||||||
Left Rear Brake Apply | -- | The EBCM enegizes the appropriate solenoids and the precharge pump motor to apply brake pressure to the left, rear wheel. The precharge pump turns off after approximately 2 seconds, but the brake pressure is held for approximately 9 seconds. Refer to Brake Pressure Modulator Valve Hydraulic Testing for a step-by-step procedure. | ||||||||||||||||
Pre-charge Bleed | -- | The EBCM commands both turbocharger (TC) isolation valve solenoids on and energizes the precharge pump to bleed air from the precharge pump, combination valve and the hydraulic circuitry between these components. Refer to Antilock Brake System Automated Bleed Procedure for a step-by-step procedure. | ||||||||||||||||
Request ABS/VSES Info. for SPS | Request Info. | This function allows you to request VIN and EBCM software information to be used when programming the EBCM using service programming system (SPS). | ||||||||||||||||
Right Front Brake Apply | -- | The EBCM enegizes the appropriate solenoids and the precharge pump motor to apply brake pressure to the right, front wheel. The precharge pump turns off after approximately 2 seconds, but the brake pressure is held for approximately 9 seconds. Refer to Brake Pressure Modulator Valve Hydraulic Testing for a step-by-step procedure. | ||||||||||||||||
Right Rear Brake Apply | -- | The EBCM enegizes the appropriate solenoids and the precharge pump motor to apply brake pressure to the right, rear wheel. The precharge pump turns off after approximately 2 seconds, but the brake pressure is held for approximately 9 seconds. Refer to Brake Pressure Modulator Valve Hydraulic Testing for a step-by-step procedure. | ||||||||||||||||
Solenoid Tests |
| This function allows the technician to command a selected dump or isolation valve solenoid On and Off to verify proper operation of the BPMV. Refer to Brake Pressure Modulator Valve Hydraulic Testing for complete procedure instructions. | ||||||||||||||||
Tire Size Calibration |
|
Important: The Yaw Rate Reference Table Reset Procedure must also be performed if the tire size is changed. Refer to Yaw Rate Reference Table Resetting . 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. | ||||||||||||||||

Refer to the scan tool manual for complete scan tool operating instructions. | ||||||||||||||
Function Test | -- | The electronic brake control module (EBCM) commands the system relay, valve solenoids, and pump motor ON and OFF. The EBCM sets a DTC if a malfunction is detected. | ||||||||||||
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. | ||||||||||||
ABS Relay | -- | This function allows the technician to command the system relay ON and OFF. | ||||||||||||
System Identification | -- | The scan tool displays the hardware and software revision of the EBCM. | ||||||||||||
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
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. | ||||||||||||
