4-4SERVICE PROCEDURE
15. Hydraulic Unit for ABS System (Except ABS 5.3 Type)

Be careful to prevent foreign particles from getting into
hydraulic unit.

When a new hydraulic unit is installed, apply a coat of
rust-preventive wax (Nippeco LT or GB) to bracket attach-
ing bolts after tightening.

Do not pull harness disconnecting harness connector.
B: INSPECTION
1. CHECKING HYDRAULIC UNIT
1) Check connected and fixed condition of connector.
2) Open hydraulic unit relay box and check for discontinu-
ity or short circuits.
