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. Turn the ignition switch to the OFF position.
2. If equipped with RPO LSJ, remove the throttle body air snorkel.
3. Clean the electronic brake control module (EBCM) (3) to brake pressure modulator valve (BPMV) (4) area of any accumulated dirt and foreign material.
4. Remove the 4 EBCM-to-BPMV retaining bolts (2).
5. Disconnect the electrical connector (1) from the EBCM (3).

Important: Do Not use a metal tool to pry the EBCM from the BPMV. Use care to ensure that the EBCM-to-BPMV mating surfaces are not scratched during EBCM removal.

6. Separate the EBCM (3) from the BPMV (4) by carefully pulling apart.

1. Clean the EBCM mating surface of the BPMV (4), with denatured alcohol, or equivalent.
2. Ensure that the EBCM (3) to BPMV (4) seal is fully seated in the groove on the EBCM (3).
3. Install the EBCM (3) to the BPMV (4). Use care when aligning the EBCM (3) to the BPMV electrical terminals (4).
4. Connect the electrical connector (1) to the EBCM (3).

Notice: Refer to Fastener Notice in the Preface section.

5. Install the 4 EBCM-to-BPMV retaining bolts (2). Tighten the bolts in a criss-cross pattern.

Tighten
Tighten the bolts to 4.5 N·m (40 lb in).

6. If equipped with RPO LSJ, install the throttle body air snorkel.
7. If a new EBCM was installed, the EBCM must be programmed. Refer to Electronic Brake Control Module Programming and Setup .
8. Turn the ignition switch to the ON position. DO NOT start engine.
9. Perform the Diagnostic System Check - Vehicle .
10. Refer to Control Module References for programming and setup information.
