Engine General Information and Diagnosis: 1A-22
Visual Inspection
Prior to diagnosis using the FI indicator light assy or SDS, perform the following visual inspections. The reason for
visual inspection is that mechanical failures (such as oil leakage) cannot be displayed on the screen with the use of FI
indicator light assy or SDS.
Engine oil level and leakage. Refer to “Engine Oil Filter Replacement” in Section 0B (Page 0B-7).
Engine coolant level and leakage. Refer to “Cooling Circuit Inspection” in Section 1F (Page 1F-4).
Fuel level and leakage. Refer to “Fuel Hose Inspection” in Section 0B (Page 0B-14).
Clogged air cleaner element. Refer to “Air Cleaner Element Cleaning” in Section 0B (Page 0B-4).
Battery condition.
Throttle cable play. Refer to “Throttle Cable Play Inspection and Adjustment” in Section 0B (Page 0B-12).
Broken fuse.
Exhaust gas leakage and noise. Refer to “Exhaust System Inspection” in Section 1K (Page 1K-3).
Each coupler disconnection.
Clogged radiator fins. Refer to “Radiator Inspection and Cleaning” in Section 1F (Page 1F-4).
