Initial Inspection and Diagnostic Overview

^ Check for blown fuses. If necessary, repair or replace harness or related part.

^ Check H.E.C. internal circuit (continuity check) before diagnosing. This is because the time control unit is directly connected to the H.E.C. which functions as an intermediate joint for input and output.

^ Check the power supply and ground circuits of time control unit. Repair or replace harness if necessary.
