DIAGNOSTIC TROUBLE CODE INDEX
Symptom Table
| Symptom | Repair order |
|---|---|
| When the sonar system is OFF, the OFF indicator does not light and the sonar buzzer does not sound. | Check sonar system OFF switch. Refer to " COMPONENT INSPECTION ". Check harness and connections for sonar system OFF switch. Replace sonar control unit. Refer to " REMOVAL AND INSTALLATION ". |
| When the sonar system is OFF, the OFF indicator lamp does not light but the sonar buzzer does sound. | Check sonar system OFF indicator lamp. Refer to " COMPONENT INSPECTION ". Check harness and connections for sonar system OFF indicator lamp. Replace sonar control unit. |
| When the sonar system is OFF, the sonar buzzer does not sound but the OFF indicator lamp lights. | Check sonar buzzer. Refer to " COMPONENT INSPECTION ". Check harness and connections between sonar buzzer and sonar control unit. Replace sonar control unit. |
