Lever switches of external lighting, indexes of turn and fog light and screen wipers form the uniform non-demountable block called by "the block of understeering switches".

This element consists of one managing director of the cascade executed on diodes and switches.

At short circuit of certain contacts of the block of the TsEKBS understeering switches distinguishes the operating influence of the driver.

Example: short circuit of contacts 12 and 14 TsEKBS defines as the command for inclusion of indexes of the right turn.

Fig. 7.93. Connection to diode contacts of the block of understeering switches

Constant connections 4-3, 12-5, 8-2, 13-14, 10-9 are used for diagnostics of the block of understeering switches and chains of connection with TsEKBS.
