1A-23 Engine General Information and Diagnosis:
Visual Inspection
Prior to diagnosis using the mode select switch 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 mode
select switch or SDS.
• Engine oil level and leakage. Refer to "Engine Oil and Filter Replacement in Section 0B (Page 0B-8)".
• Engine coolant level and leakage. Refer to "Cooling Circuit Inspection in Section 1F (Page 1F-4)".
• Fuel level and leakage. Refer to "Fuel Line Inspection in Section 0B (Page 0B-7)".
• Clogged air cleaner element. Refer to "Air Cleaner Element Inspection in Section 0B (Page 0B-2)".
• Battery condition.
• Throttle cable play. Refer to "Throttle Cable Play Inspection and Adjustment in Section 0B (Page 0B-10)".
• Vacuum hose looseness, bend and disconnection.
• Broken fuse.
• FI indicator light operation. Refer to "Combination Meter Inspection in Section 9C (Page 9C-4)".
• Each warning indicator light operation. Refer to "Combination Meter Inspection in Section 9C (Page 9C-4)".
• Speedometer operation. Refer to "Speedometer Inspection in Section 9C (Page 9C-7)".
• Exhaust gas leakage and noise. Refer to "Exhaust System Inspection in Section 1K (Page 1K-4)".
• Each coupler disconnection.
• Clogged radiator fins. Refer to "Radiator Inspection and Cleaning in Section 1F (Page 1F-5)".
