Electronic Brake Control Module Replacement Without RPO LAT

Caution: Refer to Brake Fluid Irritant Caution in the Preface section.

Notice: Refer to Brake Fluid Effects on Paint and Electrical Components Notice in the Preface section.

Notice: Always connect or disconnect the wiring harness connector from the EBCM/EBTCM with the ignition switch in the OFF position. Failure to observe this precaution could result in damage to the EBCM/EBTCM.

1. Place the ignition switch in the OFF position.
2. Remove the underhood electrical center. Refer to Underhood Electrical Center or Junction Block Replacement.
3. Without draining the coolant or removing the hoses, remove and position aside the radiator surge tank. Refer to Radiator Surge Tank Replacement.
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 outlet port to prevent brake fluid loss and contamination.

7. Carefully position aside and secure the brake pipe to provide clearance for removal of the EBCM.



8. Remove the 4 EBCM bolts (1).



9. Carefully pull the EBCM (1) from the BPMV.

Do not pry the components apart.

10. Remove the 12 EBCM seals, if necessary.

1. Install the EBCM seals, if removed.
2. Install the EBCM (1) to the BPMV.

Notice: Refer to Fastener Notice in the Preface section.




3. Install the 4 EBCM bolts (1) and tighten the bolts in a cross pattern.

Tighten
Tighten the bolts to 3 N·m (27 lb in).




4. Position the LF brake pipe to the BPMV.
5. Connect the LF brake pipe fitting (1) to the BPMV.

Tighten
Tighten the fitting to 21 N·m (16 lb ft).

6. Install the radiator surge tank. Refer to Radiator Surge Tank Replacement.
7. Install the underhood electrical center. Refer to Underhood Electrical Center or Junction Block Replacement.
8. If installing a new EBCM, program the EBCM. Refer to Control Module References.
9. Without starting the engine, place the ignition switch in the ON position.
10. Perform the Diagnostic System Check - Vehicle.
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 Procedure.
