Test sequence



- Measure direct voltage with multimeter between sockets [ F.2 ] 98 and [ F.15 ] 111 of the 35-pole socket box tester.



- Switch on ignition.



Specified value



- Voltage[11.0...15.0] V



Question



- Is the measurement value OK?



YES



The measurement value is OK.End of test



NO



The measurement value is not OK.Possible cause and remedy



- N10/1f52 (Fuse 52)



- Lines



End of test



0868
