Code U0155:87 Description

The U0155:87 diagnostic trouble code (DTC) indicates that there is a communication issue between the vehicle's engine control module (ECM) and the instrument panel cluster control module. This can result in the ECM not receiving important data from the instrument panel cluster control module, leading to potential performance issues and malfunctions within the vehicle. The instrument panel cluster control module is responsible for displaying important information to the driver, such as speed, fuel level, and engine temperature. When communication is lost with this module, it can cause the vehicle to operate inefficiently and potentially unsafe.
