Master Cylinder: Notes
CAUTION:
On models with ABS VI system, DO NOT remove hydraulic modulator/master cylinder assembly until a Gear Tension Release Function procedure has been performed. When hydraulic modulator displacement cylinder pistons are in the home position, there is a prevailing torque. This torque creates a gear tension or force on hydraulic modulator motor gears that makes motor pack separation difficult. To avoid injury or damage to motor gears, Gear Tension Relief Function briefly reverses each motor to eliminate prevailing torque. A Tech 1 scan tool is needed to perform Gear Tension Relief Function.
CAUTION:
When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES
article in GENERAL INFORMATION before disconnecting battery.
