DTC A044 - Left Front Channel Will Not Move: Notes

EBCM monitors for bound-up ESB, stuck motor or seized hydraulic modulator. When release is commanded during initialization, the ESB should release the motor, resulting in sensed current being less than commanded current (motor is spinning freely). If the motor is not moving, sensed current will be equal to stall current.

NOTE: Test numbers refer to test numbers on diagnostic chart.

Checks for proper motor movement during apply and release commands from Tech 1.
Compares EBCM command current to motor feedback current.
Checks for proper hydraulic modulator gear and piston movement.
Verifies motor can actually apply when commanded.
Determines if the malfunction is caused by a defective EBCM or by a short circuit.
