Troubleshooting Hints

IMPORTANT: Before removing Trip Calculator components, turn Ignition Switch to "OFF" and disconnect negative Battery cable.

1. Check Fuses 10 and 15 by visual inspection.
2. Check that G201, G203 and G301 are clean and tight.
^ Check for a broken (or partially broken) wire inside of the insulation which could cause system malfunction but prove "GOOD" in a continuity/voltage check with a system disconnected. These circuits may be intermittent or resistive when loaded, and if possible, should be checked be monitoring for a voltage drop with the system operational (under load).
^ Check for proper installation of aftermarket electronic equipment which may affect the integrity of other systems (refer to General Troubleshooting Procedures). Diagnostic Aids
^ Refer to System Diagnosis.
