1990 Toyota Camry

Hi there,

This is the E.C.U. Fault light. The ecu has set a fault code for something in the engine management system, This code can be retrieved by bridging TE & E1 at the diagnostic link under the bonnet, with the ignition on, the light will flash a code it might be 2 flash's, pause and 4 flashes, this is code 24 and so on.
These codes are use to determine faults that have developed in the electronics and sensors.
