Few days back when my mechanic came to my home in the morning and switch On my car himself
the gear lever box was already opened and the relay was naked infront of us
We tap the tap , tap the dashboard , tap the grip/connectors but all failed
Check light doesn't turn On
He used her Tester to check the current in relay
but there was No current at all
Then he removed the under seat car's carpet to bring the ECU out
Still no light
As soon as he touch and tried to removed the 10 holes connector attached with ECU
Suddenly the Check Light Comes
He said k ECU mein current tha but relay tak nai aa raha tha , jis ki waja say check light On nai hote
According to him the current first comes to ECU and then it moves to Relay
(if no ECU..........no current in relay)
Is it So in real ?
