The team at the ALLDATA Repair Info Centre Service have solved a problem affecting certain Tesla Model Y vehicles in relation to the horn and its failure to sound when pressed. 

 
The team at the ALLDATA Repair Info Centre Service was recently presented with an issue on a 2022 Tesla Model Y. The vehicle owner revealed to the technician that when the horn was pressed on steering wheel, it didn’t make any sound. 

A basic diagnostic check was carried out, and it was discovered that no supply was present at the horn. Due to the nature of the vehicle and inability to source a fuse for the horn, however, the technician turned down the work.

Following Tesla’s recent integration to the ALLDATA portal, THE ALLDATA technical team have found a solution. Although relatively uncommon, some vehicles can experience an issue with the connector, the one that sits behind the steering wheel, in that it can loosen or even disconnect completely.

The horn on these vehicles is supplied though their body control module, so, as the customer stated that there was no power to the horn, it was likely that the issue was linked to the horn connector.

The first procedure was to disconnect the LV power supply and separate the driver’s airbag from the steering wheel. The next task was to check the connector, as depicted below, making sure that male and female parts were thoroughly secured together.

The final job was just to reassemble the components and test.
