REMOVAL

Note. If the ABM needs to be replaced, the rear axle type and tire revolutions per mile must be programed into the new ABM. For axle type refer to DIFFERENTIAL & DRIVELINE . For tire revolutions per mile, (Refer to TIRES/WHEELS/TIRES - SPECIFICATIONS) . To program the ABM refer to the Appropriate Diagnostic Service Information.

  1. Remove the HCU from the vehicle «(Refer to BRAKES/HYDRAULIC/MECHANICAL/HCU (HYDRAULIC CONTROL UNIT)»(ref-247606-S21823442392007020100000) - REMOVAL).
  2. Remove the module mounting screws (1).
  3. Disconnect the pump electrical connector (3) from the HCU (2).
  4. Remove the module (1) from the HCU (2).

INSTALLATION

Note. If the ABM needs to be replaced, the rear axle type and tire revolutions per mile must be programed into the new ABM. For axle type refer to DIFFERENTIAL & DRIVELINE . For tire revolutions per mile (Refer to TIRES/WHEELS/TIRES - SPECIFICATIONS) . To program the ABM refer to the Appropriate Diagnostic Service Information.

  1. Position the module (1) on the HCU (2).
  2. Install the mounting screws (1) and tighten to 6 N.m (53 in. lbs).
  3. Install the pump electrical connector (3) to the module (4).
  4. Install the HCU to the vehicle «(Refer to BRAKES/HYDRAULIC/MECHANICAL/HCU (HYDRAULIC CONTROL UNIT) - INSTALLATION»(ref-247606-S03506903102007020100000) ).
  1. Connect the Power Distribution Center (PDC) (3) to the Front Control Module (FCM) by lining up the electrical connector and pushing the two together.
  2. Install the four fasteners (2) securing the FCM (1) to the PDC (3).
  3. Install the Integrated Power Module (IPM), «(Refer to ELECTRICAL/POWER DISTRIBUTION/INTEGRATED POWER MODULE - INSTALLATION)»(ref-247631-S35411468202007020100000) .
  4. Connect the battery negative cable.

The PCM (1) is attached to the right-inner corner of the engine compartment.

CAUTIONCertain ABS systems rely on having the Powertrain Control Module (PCM) broadcast the Vehicle Identification Number (VIN) over the bus network. To prevent problems of DTCs and other items related to the VIN broadcast, it is recommend that you disconnect the ABS CAB (controller) temporarily when replacing the PCM. Once the PCM is replaced, write the VIN to the PCM using the DRB scan tool. This is done from the engine main menu. Arrow over to the second page to "1. Miscellaneous". Select "Check VIN" from the choices. Make sure it has the correct VIN entered before continuing. When the VIN is complete, turn off the ignition key and reconnect the ABS module connector. This will prevent the setting of DTCs and other items associated with the lack of a VIN detected when you turn the key ON after replacing the PCM.
CAUTIONUse the DRB scan tool to reprogram the new PCM with the vehicles original identification number (VIN) and the vehicles original mileage. If this step is not done, a Diagnostic Trouble Code (DTC) may be set.

The PCM (1) is attached to the right-inner corner of the engine compartment.

To avoid possible voltage spike damage to the PCM, ignition key must be off, and negative battery cable must be disconnected before unplugging PCM connectors.

  1. Position PCM (3) to vehicle.
  2. Install three PCM mounting bolts (2).
  3. Tighten bolts to 3-5 N.m (30-40 in. lbs.).
  4. Be sure ground strap (4) is secured both at bottom of PCM, and at inner-fender.
  5. Check pin connectors in the PCM. Also check the four 38-way connectors (2) for corrosion or damage. Repair as necessary.
  6. Install the four 38-way connectors (2) to PCM.
  7. Connect negative battery cable.
  8. Use the diagnostic scan tool to reprogram new PCM with vehicles original Identification Number (VIN) and original vehicle mileage. If this step is not done, a Diagnostic Trouble Code (DTC) may be set.
