are OK, warning lights, the ABS warning light -K47- and traction
control indicator light -K86- go out after approximately three seconds.

Repair Manual, Electrical Equipment, Repair Group 90.



The battery voltage is insufficient. None of the lamps in the instrument
cluster light up. Check the battery. The ABS warning light -K47- does not light up during the self-test. There
is a short to Ground (GND) in the wiring that controls the ABS/EDL
warning light between terminal 32 of the ABS control module -J104- and
the instrument cluster. This malfunction does NOT influence the control
of the traction control indicator light.
