ABS Motor Pack Replacement
REMOVAL PROCEDURE
1. Remove the Hydraulic Modulator Assembly.
2. Remove the Torx head screws attaching the gear cover.
3. Remove the gear cover from the Brake Motor pack.
4. Remove the Torx head screws that attach the Brake Motor Pack to the Hydraulic Modulator.
5. Remove the Brake Motor Pack from the Hydraulic Modulator.
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.
IMPORTANT: If the disassembly of the modulator/master cylinder assembly was caused by an ABS 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 Brake System. The
Automated ABS brake motor pack Diagnosis Test isolates the motor pack or brake modulator.
IMPORTANT: No repair of the motor pack is authorized. Replace as an assembly.
