Chevrolet Captiva Service & Repair Manual: ABS Control Module R&R

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.

Removal

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.
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, Fig. 1.
7. Carefully position aside and secure the brake pipe to provide clearance for removal of the EBCM.
8. Remove the four EBCM bolts (1), Fig. 2.
9. Carefully pull the EBCM (1) from the BPMV. Do not pry the components apart, Fig. 3.
10. Remove the 12 EBCM seals, if necessary.

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.
6. Install the radiator surge tank.
7. Install the underhood electrical center.
8. If installing a new EBCM, program the EBCM.
9. Without starting the engine, place the ignition switch in the ON position.
10. 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.
