With ABS
ABS CONTROL MODULE AND HYDRAULIC CONTROL UNIT (ABSCM&H/U)
REMOVAL
1. Disconnect the ground cable from the battery.
2. Use compressed air to remove water and dust around the ABSCM&H/U.
NOTE: If the terminals become dirty, it may cause improper contact.
3. Lift the lock lever and disconnect the ABSCM&H/U connector.
CAUTION: Do not pull on the harness when disconnecting the connector.
4. Remove the harness clip.
5. Disconnect the brake pipes from the ABSCM&H/U.
6. Wrap the brake pipe with a vinyl bag so as not to spill the brake fluid on the vehicle body.
CAUTION: If brake fluid is spilled on the vehicle body, wash it off immediately with water and wipe clean.
7. Remove the nuts and remove the ABSCM&H/U.
CAUTION:
^ Do not drop or bump the ABSCM&H/U.
^ Do not turn the ABSCM&H/U upside down or place it sideways for storage.
^ Be careful not to let foreign matter enter into ABSCM&H/U.
^ Be careful that no water enters the connectors.
8. Remove the ABSCM&H/U bracket.
INSTALLATION
1. Install the ABSCM&H/U bracket.
Tightening torque: 33 N-m (3.3 kgf-m, 24 ft-lb)
2. Align the damper groove of the ABSCM&H/U to the bracket side claw, and install the ABSCM&H/U with new nuts (Part No. 023506000).
NOTE: Check the identification marks of the ABSCM&H/U.
Tightening torque: 7.5 N-m (0.76 kgf-m, 5.5 ft-lb)
3. Connect the brake pipes to their correct ABSCM&H/U positions.
Tightening torque: 15 N-m (1.5 kgf-m, 10.8 ft-lb)
4. Using a harness clip, secure the ABSCM&H/U harness to the bracket.
5. Connect the connector to the ABSCM&H/U.
NOTE:
^ Be sure to remove all foreign matter from inside the connector before connecting.
^ Make sure the ABSCM&H/U connector is securely locked.
6. Bleed air from the brake system.
REPLACEMENT
CAUTION:
^ Because the seal of the ABSCM cannot be replaced, do not pull or peel it by lifting it up.
^ Because the screw of the H/U will become slightly worn in every replacement procedure, 5 times is the maximum number of times for replacement. If a problem is found such as not being able to torque the screw to specifications even before 5 replacement operations are performed, replace the H/U body.
^ When installing the ABSCM, always use new screws.
^ When the sealing surface of the ABSCM or H/U is dirty or damaged and it cannot be removed or repaired, replace with a new part.
1. Remove the ABSCM&H/U bracket.
2. To prevent entry of foreign objects and brake fluid leakage, plug the oil pressure port of the ABSCM&H/U using a screw plug, etc.
3. Set the pump motor section of the removed ABSCM&H/U face down on a vise.
NOTE: Before securing a part in a vise, place cushioning material such as wood blocks, aluminum plate or cloth between the part and the vise.
4. Using TORX bit E5, remove the four screws of ABSCM.
NOTE: These screws cannot be reused.
5. Slowly pull out the ABSCM upward from the H/U.
NOTE: To prevent damaging of coil section, remove the ABSCM straight up from H/U without twisting.
6. Make sure there is no dirt or damage on the sealing surface of the H/U.
CAUTION:
^ Do not clean the ABSCM and H/U by applying compressed air.
^ Even if damage is found on the H/U seal, do not attempt repair by filing or with a metal scraper. To remove the seal residue, always use a plastic scraper. Do not use chemical such as paint thinner, etc., to clean.
7. Position the coil of the new ABSCM to align with the H/U valve.
8. To prevent deformation of the ABSCM housing cover, hold the corner of ABSCM and install it to the H/U without tilting.
9. Using a TORX bit E5, attach/tighten new screws in the order of (1) through (4).
CAUTION: Always use new screws.
Tightening torque: 1.5 N-m (0.15 kgf-m, 1.1 ft-lb)
10. Check that there is no foreign matter in mating surface between the ABSCM and H/U.
11. Using a TORX bit E5, tighten the screws in the order of (1) through (4) again.
Tightening torque: 3 N-m (0.3 kgf-m, 2.2 ft-lb)
12. Check that there is no gap in the mating surface between ABSCM and H/U.
13. Install the ABSCM&H/U to the vehicle.
