Attachment III - Technical Information
OVERVIEWThis program involves replacement of the ABS module. The module is secured to the ABS hydraulic control unit (HCU) located in the engine compartment.
NOTE:
HCU removal is not required for module replacement.
REMOVAL
NOTE:
The new ABS Module does not contain the suspect diode, therefore, the heat shield that may have been installed for Safety Recall 04S22 is no longer required.
1. Remove the heat shield (if equipped).
2. Remove the three (3) screws attaching the radiator coolant reservoir and position the reservoir aside.
3. Disconnect the module wire harness connector by releasing the lock tab and pulling the connector from the module. See Figure 1.
4. Remove the four (4) Torx head screws securing the module to the HCU. See Figure 2.
5. Lift the module slightly and disconnect the ABS pump motor connector, then remove the module from the vehicle. See Figure 3.
INSTALLATION
1. Position the new module above the HCU and connect the ABS pump motor connector.
2. Carefully position the new module onto the HCU and install the four (4) screws. Tighten to 4 Nm (35 lb-in).
3. Connect the module wire harness connector and engage the locktab.
4. Position and install the radiator coolant reservoir. Tighten the three (3) screws to 12 Nm (106 lb-in).
NOTE:
The new ABS Module does not contain the suspect diode, therefore, the heat shield that may have been installed for Safety Recall 04S22 is no longer required.
5. Turn the ignition key to ON and verify the ABS indicator light on the instrument panel goes out after approximately five (5) seconds.
