11.39. Sound signal


1. On cars "Toyotas 4 Runner/Hilux/Surf" 2 sound signals established on both parties from a radiator are provided.
2. For check disconnect the socket and directly connect the battery to a signal. In the absence of a sound replace a signal.
3. If the sound is, check tension on a conclusion when pressing the signal button. In the presence of tension check connection with weight.
4. If tension is not present, check the relay. It is necessary to consider that relays of a sound signal generally have 4 or the 3rd conclusion (3-output relays have external connection with weight).
5. If relays are serviceable, check tension on relay conclusions. If tension is not present, check wires from a safety lock to the relay.
6. If on relay conclusions tension is, press the button of a signal and check a chain of connection with weight between the relay and the button. If break is not present, replace the signal button.
7. If via the button the chain on weight becomes isolated, check existence in a chain from the relay for the button of break or short circuit.


1. For replacement of a sound signal disconnect the socket and turn off a bolt (it is specified by an arrow).
2. Remove a signal and establish the new.
3. Further installation is carried out upside-down.
