EL - 188 Electrical system –circuit

IN System description:

The battery is connected through the fuse F\L3 into the vehicle frame fuse box, and individually connected
DI through fuses F03 and F04 to the pin 3 and pin of the ignition switch B035, as the power supply for the
ignition switch.

ACC power supply:
EG
When the ignition switch is at the ACC position, the pin 1 and pin 3 of ignition switch B035 are activated. The

ACC power supply is output through pin 1 to the cigarette lighter and radio player system.
TR
ON power supply:

When the ignition switch is at ON position, the pin 2 and pin 3 of ignition switch B035 are activated to send
AX
IG1 signal to the pin 85 of the IG1 relay. IG1 relay coil is powered up and output IG1 power supply as the
trigger power for the windshield wiper system, ABS system, combination instrument and other system;
FR meanwhile, the pin 4 and pin 5 of the ignition switch B035 are activated to output IG2 signal, to the pin of

IG2 relay 85. IG2 relay coil is powered up to out the IG2 power supply and the trigger power supply for the
A/C, dryers and other systems.
ST
ST power supply:

Step on clutch pedal, and put the transmission into neutral position. Put the ignition switch into ST position,
BR
the pin 4 and pin 6 of the ignition switch B035 are activated. The pin 6 outputs ST signal and the startup relay

coil is powered up to close the contacts under the control of the engine ECU. The battery current flows
BW
through the startup relay to the starter which is earthed, and the engine is started. Once the engine is started,
the starter stop working, and the ignition switch shifts automatically from the ST position to ON position.
