Brake Pressure Modulator Valve Assembly Replacement Except V275

Caution: Refer to Battery Disconnect Caution in the Preface section.

1. Disconnect the negative battery cable.
2. Remove the cooling surge tank. Refer to Radiator Surge Tank Replacement .



3. Disconnect the ABS wiring harness connector (2) from the socket on the electronic brake control module (EBCM).
4. Cover the connector and the socket with shop cloths to protect it from the brake fluid.

Important: Do not allow air from the master cylinder into the hydraulic unit or the brake pipes. If air gets into the hydraulic unit, perform a bleeding procedure using a scan tool programmed for the ABS system. As long as no air enters the hydraulic unit, a simple bleeding procedure is all the system will require.
