Hot start problem on Yaris D4-D
(Translated from French)
Summary of the thread
A Toyota Yaris D4-D experiences a hot start problem where the engine won't restart after being turned off when hot, accompanied by a flashing 'cool' temperature light and a 'CLAC' sound. The issue resolves after the engine cools down. Despite replacing the alternator and coolant temperature sensor, the problem persists. Suggested solutions include checking the battery connections, inspecting the starter relay and its connections, and examining engine ground connections for corrosion or looseness.

Check the battery connections and ensure they are clean and tight. A weak or failing battery can cause starting issues, especially when the engine is hot. If the problem persists, consider having the battery tested. Let me know how it goes or if you have any further questions!
Hello, thank you for your answer, the battery, alternator & starter are new.

Inspect the starter relay and its connections. A faulty relay can cause starting issues when the engine is hot. If the relay seems fine, consider checking the engine ground connections for any corrosion or looseness. Keep me updated on your progress or if you have more questions!
