Installation - ICU

  1. Install the ICU onto its mounting bracket.
  2. Install the 3 bolts attaching the ICU to the mounting bracket. (Figure ). Tighten the 3 mounting bolts to 11 N.m (97 in. lbs.)
  3. Install the four brake tubes going to the brakes into their respective outlet ports on the ICU HCU. (Figure ). Using a crow foot on a torque wrench, tighten the four brake tube nuts to 17 N.m (145 in. lbs.).
    NOTE: When installing the brake tubes from the master cylinder on the HCU, the brake tube with the small tube nut is to be installed in the forward-most port on the HCU with the small end going toward the master cylinder secondary port.
  4. Install the primary and secondary brake tubes from the master cylinder onto the HCU. (Figure ). Do not completely tighten the primary and secondary tubes at this time.
  5. Connect the primary and secondary brake tubes to the master cylinder ports. (Figure ).
  6. Using a crow foot on a torque wrench, tighten the primary and secondary brake tube nuts at both the master cylinder and HCU to 17 N.m (145 in. lbs.).
    7. CAUTION: Before installing the 24-way connector in the CAB, be sure the seal is properly installed in the connector.
  7. Install the 24-way connector into the socket of the CAB as follows:
    • Position the 24-way connector in the socket of the CAB and carefully push it down as far as possible. (Figure ).
    • When the connector is fully seated into the CAB socket, push the connector lock inward. This pulls the connector into the socket of the CAB and locks it in the installed position.
  8. Position the battery tray back in place. Install the two bolts, then the two nuts mounting the battery tray to its bracket. (Figure ). Tighten the two bolts and nuts to 15 N.m (135 in. lbs.).
  9. Reinstall the air cleaner box onto its grommeted alignment post. (Figure ).
  10. Install the one nut and one bolt securing the air cleaner box in place, then connect the wiring harness connector at the air inlet sensor.
  11. Install the battery and clamp it in place. Tighten the hold-down clamp bolt to 12 N.m (105 in. lbs.).
  12. Connect the positive, then the negative (ground) cable on the battery.
    NOTE: The ICU may need to be initialized using the DRBIII(R) scan tool after ICU installation. Refer to DIAGNOSTIC INFORMATION AND PROCEDURES  .
  13. Bleed the base brakes and ABS hydraulic systems. (Refer to STANDARD PROCEDURE - ANTI-LOCK BRAKE SYSTEM BLEEDING  ).
  14. Fill the master cylinder to the proper fill level.
  15. Road test the vehicle to ensure proper operation of the base and anti-lock brake systems.
