Removal
| 1. |
Place the ignition switch in the OFF
position. |

Remove the underhood electrical center. |
| 3. |
Without draining the coolant or removing
the hoses, remove and position aside the radiator surge tank. |
| 4. |
Clean the electronic brake control
module (EBCM) to brake pressure modulator valve (BPMV) area of any
dirt or debris. |
| 5. |
Disconnect the EBCM electrical connector
by lifting the locking lever upward. |
| 6. |
Disconnect the LF brake pipe fitting
(1) from the BPMV. Cap the brake pipe fitting and plug the BPMV

Carefully pull the EBCM (1) from the
BPMV. Do not pry the components apart, Fig. 3. |

Installation
| 1. |
Install the EBCM seals, if removed. |
| 2. |
Install the EBCM to the BPMV. |
| 3. |
Install the EBCM bolts and torque
the bolts in a cross pattern to 27 inch lbs. |
| 4. |
Position the LF brake pipe to the BPMV. |
| 5. |
Connect the LF brake pipe fitting to
the BPMV and torque to 16 ft. lbs. |

Perform the diagnostic system check. |
| 11. |
Observe the feel of the brake pedal
after performing the diagnostic system check. If the pedal now feels
spongy, air may have been in the secondary circuit of the brake
modulator assembly, which may have been introduced into the primary
circuit. If the pedal feels spongy, perform the antilock brake system
automated bleed. |
