SERVICE PROCEDURE

Using Integrated Diagnostic System (IDS), check for DTCs.

Replace signal return splice with 0.75 mm (18 AWG) wire using the crimp method. Affected splice numbers are S132 and S133. Refer to Wiring Diagram, Section 5-1.
Remove the engine appearance cover.
Remove the air cleaner tube from the housing.
Disconnect the tube for the engine sound symposer at the intake manifold.
Position and secure the upper radiator hose aside using mechanics wire or equivalent.
To increase access to the wire harness release the support clip from harness to coolant inlet valve hose.
Remove enough harness wrap to locate and replace splices.
Backfill the crimp with solder before sealing repair with heat shrink tube.
