V3800-CR-TE4,V3800-CR-TIE4, DM
Heat the accelerator sensor and other electrical components with a hair dryer.
Verify whether or not the voltage value (resistance value) changes.
NOTE
• Do not exceed 60 °C (140 °F) (still touchable by hand) when heating.
• Do not remove the component case and add heat directly to
electronic parts.
Verify whether or not malfunction symptoms occur under heavy engine loads
(headlights, A/C, wiper, etc. switches ON).
If any commercial electrical products have been installed, remove them and
verify whether or not the malfunction symptoms occur.
If it is thought that the malfunction occurs in rainy or high temperature weather, spray the machine
with water and verify whether or not the malfunction occurs.
NOTE
• Do not spray water directly onto the engine. Spray water mist on the entire surface of
the radiator to indirectly change the temperature and humidity of the engine
compartment.
• Do not spray water directly on electrical parts.
