1) Reasons why the indicator lamps light up






X1) The vehicle is equipped with ASR:
There is a malfunction that affects only the ASR system. The ABS and EDL systems are
not deactivated. Check DTC memory page 01

ASR is switched off via the traction control button. If the traction control indicator light
does not light up in this case, check the switch and the indicator light, carry out the
"Electrical test", steps 10 and 11 page 01
-166
.
ASR is in adjustment mode. The traction control indicator light blinks 3 times per second.Short circuit to B+ in the traction control button: The traction control indicator light
switches off five minutes after ignition is switched on. The lamp remains constantly lit after ignition is switched on, but none of the above
mentioned conditions are true. There is a short to Ground (GND) in the wiring that
controls the traction control indicator light between terminal 20 of the ABS control module
-J104- and the instrument cluster.



There is an irregularity present or a complaint has been made. The indicator lamps go
on during the self-test and then go out. The possible causes are as follows: The DTC "Brake light switch -F-" is stored in DTC memory , check DTC memory page 01
-187
.
The DTC "ABS/instrument cluster electrical connection" is stored in DTC memory , check
DTC memory page 01
