Electronic Brake Control Module Replacement

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

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

Caution: 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.
3. Without draining the coolant or removing the hoses, remove and position aside the radiator surge tank. Refer to Radiator Surge Tank Replacement : Diesel  → Petrol Engines .
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 left front brake pipe fitting (1) from the BPMV.
7. Cap the brake pipe fitting and plug the BPMV outlet port to prevent brake fluid loss and contamination.
8. Carefully position aside and secure the brake pipe to provide clearance for removal of the EBCM.



9. Remove the 4 EBCM bolts (1).




Note: Do not prise the components apart.

10. Carefully pull the EBCM (1) from the BPMV.
11. Remove the 12 EBCM seals, if necessary.

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

Caution: Refer to Fastener Caution in the Preface section.




3. Install the 4 EBCM bolts (1) and tighten the bolts in a cross pattern to 3 N·m (27 lb in).



4. Position the left front brake pipe to the BPMV.
5. Connect the left front brake pipe fitting (1) to the BPMV and tighten to 21 N·m (16 lb ft).
6. Install the radiator surge tank. Refer to Radiator Surge Tank Replacement : Diesel  → Petrol Engines .
7. Install the underhood electrical center.
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.
12. If the pedal feels spongy, perform the Antilock Brake System Automated Bleed .
