Nig ht lam p adju sting circuit
The CA N data bus designed by the BOSCH c ompany is applied b y
Chery A5, sh own as fig ure 14-8. This enables the data communication of
eac h compute r, and forms the on-board network syst em. The in strument is
con nectted to the engine EMS、A BS、front ISU computer by CAN line and
sha re the data. The CA N end of instrumen t is 29、30; the CAN end of
eng ine ECU is 62、81;and the CAN end of front ISU is A25、A26.
①BUS line test
The inspect of connect ca pability、 open circuit or short circuit、
com puter power or gro und.
② Close the ign ition swi tch, cont rol the unit plug, and do not
connect the wiring harness plug at the tim e. Test the resistance between
the 62nd and 81st pin of A5 en gine control unit, this is the resistance
val ue of the d ata trasmission end port, the prescripti ve value is 123Ω, if it
is not so, please replace the engine control unit.
③DTC logical d ecision.
④Signal wavefor m test.
