What engine ? Engine Controls and Fuel - 3.5L Engine Controls and Fuel - 3.9L Engine Controls and Fuel - 5.3L DTC P0069: Manifold Absolute Pressure-Barometric Pressure Correlation Circuit/System Description The BARO sensor has a 5-volt reference circuit, a low reference circuit, and a signal circuit. The control module supplies 5 volts to the BARO sensor on a 5-volt reference circuit, and provides a ground on a low reference circuit. The BARO sensor provides a voltage signal to the control module on a signal circuit relative to the ambient pressure changes. The manifold absolute pressure (MAP) sensor has a 5-volt reference circuit, a low reference circuit, and a signal circuit. The control module supplies 5 volts to the MAP sensor on a 5-volt reference circuit, and provides a ground on a low reference circuit. The MAP sensor provides a voltage signal to the control module on a signal circuit relative to the intake manifold pressure changes. The control module compares the BARO sensor to the MAP sensor in order to monitor the BARO sensor operation. DTC C0899 : Device Voltage Low Circuit/System Description The electronic brake control module (EBCM) monitors the ignition voltage level available for system operation. A low voltage condition prevents the system from operating properly. Circuit/System Testing Measure the voltage at the battery terminals. ? If less than 12 volts, charge and test the battery. With a scan tool, read the ignition voltage in the EBCM data list. Verify that battery terminal voltage and ignition voltage readings do not differ more than 1 volt. ? If the difference is more than 1 volt, test the ground circuit of the EBCM for high resistance or replace the EBCM. If OK, test the charging system.

After you have manually bled the system, turn the ignition on & put the ABS module in automatic bleed mode with a scan tool. Then, just hold the pedal down. The ABS will cause the pedal to go up & down several times & will stop when bleeding is complete.
