The payment provides inclusion of a light signal after fulfilment of certain run when there comes turn of service of this or that knot or the unit. The payment represents the onboard computer which memory eats from separate batteries recharged nickel-kadmievyh. Payment deenergizing is provided with the special device connected to a diagnostic socket. Battery working life – about 6 years after which it is necessary to replace it.

Batteries are recharged from an onboard network of the car. For the term of operation temperature conditions, especially warmly strongly influence. At raised temperatures tightness of batteries and electrolits can be broken can get on a guard of devices.

Malfunction of the auxiliary battery leads to infringement of indications of a part of devices – a tachometre and the temperature index, and also to increase of noise of the receiver and to impossibility of deenergizing of alarm lamps. Conclusions of batteries are soldered to a payment, therefore their replacement is expedient for executing in a workshop for what it is necessary to remove a guard of devices and a payment.

The prevention

At removal of a guard of devices and payments take measures against casual breakdowns of electronic components by a static electricity.
