TCS Motor Pack Replacement

REMOVAL PROCEDURE





1. Remove the gear cover (3).

IMPORTANT: Use care when handling the motor pack to avoid damaging the motor pack connector. Make sure brake fluid does not accidentally intrude into the motor pack. Brake fluid in the motor pack may cause a premature failure of the motor pack.

IMPORTANT: Use care when handling the motor packs. Replace the motor packs if the motor packs are dropped or damages during handling.

2. Remove the four Torx head screws (5) that attach the motor pack (1).
3. Remove the motor pack assembly (1).

IMPORTANT: If the disassembly of the modulator/master cylinder assembly was caused by an TCS hydraulic functional test that did not pass, the Automated ABS brake motor pack Diagnosis Test should be performed. Refer to Scan Tool diagnostics in Antilock Brakes. The Automated ABS brake motor pack Diagnosis Test isolates the motor pack or brake modulator.

No repair of the motor pack is authorized. Replace as an assembly.

INSTALLATION PROCEDURE





1. With either of the modulators positioned upside down, rotate each TCS modulator gear clockwise until movement stops.

The above procedure will cause the following conditions:
^ The pistons on the TCS modulator will be positioned very close to the bottom of the modulator bore.
^ The brake bleeding procedure becomes simplified.

IMPORTANT: Use care when handling the motor packs. Replace the motor packs if the motor packs are dropped or damaged during handling.

Align each of the three motor pack pinions (two are on the TCS) with the modulator gears.

2. Install the motor pack (1) to the modulator assembly (6).
3. Install four Torx head screws (4).
^ Tighten the Torx head screws to 4.5 Nm (40 inch lbs).

NOTICE: Refer to Fastener Notice in Service Precautions.

4. Install the gear cover (3) onto the modulator/brake master cylinder assembly.
