ABS (ANTI LOCK) warning lamp, (MIU 2)
|
The lamp does not light up when the ignition switch is turned to the Drive
position.
1.
|
If the lamp does not light up the
bulb is probably faulty and will have to be changed.
If the lamp still does not light up after changing the bulb, continue with point 2.
|
2.
|
Connect a BOB to the main instrument display panel's 56-pin connector.
|
3.
|
Check the operation of the main instrument display panel and the lamp by
grounding pin 16 on the BOB with the ignition switched on.
First make sure that the central warning lamp is not alight. The ABS warning lamp and
the central warning lamp should light up.
If only the central warning lamp lights up, then the ABS warning lamp is faulty. Continue
with point 4. If both lamps light up, there is an open circuit in the lead connected to the ABS
control module. Continue with point 5.
If none of the lamps light up, the fault is probably in the main instrument display
panel's processor card. Continue on
.

4.
|
Change the bulb. If the lamp still fails to light up when activated, check that the
new bulb is OK by fitting it in place of another bulb in the main instrument display panel that
does light up.
If the lamp still does not light up, there could be an internal fault in the main instrument
display panel. Remove the main instrument display panel's rear section complete with
processor card and check that all leads connected to the connector marked CN4 are securely
located. If any lead has worked loose or is broken, continue on
.
If the connections in the connector are OK, the fault is probably in the intermediate part
with bulbs and indicating instruments. Continue on
.
|
5.
|
Check that the wiring between the main instrument display panel and the ABS
control module is OK by connecting a BOB to the 25-pin ABS control module connector (the
main instrument display panel and ABS control module should not be connected).
|
6.
|
Check for an open circuit by taking a reading across pin 16 on the BOB
connected to the main instrument display panel and pin 1 on the BOB connected to the ABS
control module.
|
7.
|
If the lead is OK, continue fault diagnosis as described in "Brakes, ABS"
.
