BLEEDING SYSTEM
NOTICE: Prior to bleeding the brakes, the front and rear displacement cylinder pistons must be returned 'to the top most position. Using a Tech 1 or
T-100 (CAMS), select F5: Motor Rehome. Motor rehome function cannot be performed if current DTCs are present. If DTCs are present, the vehicle
must be repaired and DTCs cleared before performing the motor rehome function.
Start engine and allow it to run for at least 10 seconds (with foot off brake), this will cause the ABS to initialize itself. Make sure the ABS indicator lamp
is "OFF" after about 3 seconds. If the lamp remains "ON", a Tech 1 must be used to diagnose the illumination of the indicator lamp. If lamp goes "OFF"
and stays "OFF," repeat this procedure one more time. Now using a Tech 1 or T-100 (CAMS), enter the manual control function and "Apply" the front
and rear motors. The entire brake system should now be rebled following either "Pressure Bleeding" or "Manual Bleeding."
