-K86- Possible reasons why the indicator lamps light up

A self-test is performed after the ignition is switched on. If all systems
are OK, warning lights, the ABS warning light -K47- and traction
control indicator light -K86- go out after approximately three seconds.
If the indicator lamps do not light up, check the relevant lamps carry
out "Electrical Test", steps 17 and 19. The possible causes are as
follows:
Electrical Wiring Diagrams, Troubleshooting & Component Locations
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.

Also observe notes on the next page.
The indicator lights did not go out after the self-test. However, the red
"brake system malfunction" symbol did not go on. The On Board
Diagnostic recognized a malfunction, which deactivated the
ABS/EDL/ASR/ESP. However, the "Electronic Brake Distribution" (EBD)
remained activated. Check DTC memory page 01
-356
.
The ESP driving test may have been activated page 01
-250
Check the voltage supply for the red "brake system malfunction" symbol.
Carry out "Electrical test", step 18. If the control is malfunctioning, see
the next example for lighted indicator lights. During the last drive, a dynamic malfunction of the wheel speed sensor
occurred or a malfunction in the ABS return flow pump -V39- occurred.
In this case, the indicator lights automatically go off after the vehicle is
started, and has exceeded a speed of 2.75 km/h or a check of the return
flow pump indicated it is OK.

Continuation from preceding page.
A DTC is stored in the DTC memory the first time the vehicle exceeds 6
km/h, if the voltage supply to the ABS control module -J104- is between
7 and 10 volts and the indicator lights go on. If during the drive, the
voltage supply to the ABS control module -J104- exceeds 10 volts, the
indicator light go out. The DTC remains in the memory. "Check DTC

WARNING!
The brake system is only partially functional. Because brake pressure at
the rear wheels is no longer regulated vie Electronic Brake Distribution
(EBD), the rear wheels can lock even during light braking (excessive
braking at rear axle). This can cause the rear of the vehicle to break
loose and thereby cause and accident.
Note: For vehicles with automatic transmission, the red "brake system
malfunction" symbol does not appear immediately after the ignition is
switched on. Instead, the note "Depress brake pedal before engaging gear"
appears in the display. Press the brake pedal and select a gear. The red
brake warning light appears, if the light control is working properly.
A malfunction deactivated the ABS/EDL, ASR/ESP and the "Electronic
Brake Distribution" (EBD).Check DTC memory page 01

No DTCs are stored in DTC memory. The ABS and traction control
warning lights do not go out after the self-test, and three seconds
after the ignition is switched on the red "brake system malfunction"
symbol goes on. There is an open circuit or short circuit to B+ in the wiring that
controls the traction control indicator light between terminal 32 of
the ABS control module -J104- and the instrument cluster; carry
out "Electrical test" step 17. Voltage supply for control module less than 7 volts; carry out
"Electrical test" step 21.
