CHECK ACS warning lamp (pin 27)
The above indicator and warning lamps are supplied with battery voltage from the main
instrument display panel (+15 supply) and grounded in their respective systems outside
the main instrument display panel.
|
If none of the above indicator lamps work, fuse 17 has probably blown. The
indicator lamp does not light up when activated.
|
1.
|
If the lamp does not light up as
it should, the bulb is probably faulty and must be changed. 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.
|
|
2.
|
If the bulb is intact, check the main instrument display panel and the wiring
between it and the bulb's sensor by connecting a BOB to the 56-pin connector behind
the main instrument display panel (which should be connected).
|
|
3.
|
Switch on the ignition.
Ground the pin on the BOB corresponding to the bulb connection.
If the bulb lights up, there is an open circuit in the wiring between the main instrument
display panel and the bulb's sensor or in the sensor. Investigate the cause and take
appropriate action.
If the bulb does not light up, the fault is in the main instrument display panel. Continue
with point 4.
|
|
4.
|
Remove the main instrument display panel's rear section complete with
processor card and check that all leads between the processor card and the intermediate part
are securely located. If any lead has worked loose or is broken, continue on
. If the connections are OK, the fault is probably in the intermediate part with
bulbs and indicating instruments. Continue on
.

panel and supplied with battery voltage from systems outside the main instrument display
panel.
|
None of the above indicator lamps (except the EXH lamp) light up when
activated.
|
1.
|
The fault could be because the
bulb's driver stage on the processor card is faulty. Continue on
.
|
The indicator/warning lamp does not light up when activated.
|
1.
|
If the lamp does not light up as
it should, the bulb is probably faulty and must be changed.
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.

the main instrument display panel (which should be connected).
|
|
3.
|
Switch on the ignition.
Connect a power supply to the bulb by connecting pin 15 to the corresponding pin on
the BOB to which the bulb is connected.
If the bulb lights up, there is an open circuit in the wiring between the main instrument
display panel and the bulb's sensor or in the sensor. Investigate the cause and take
appropriate action.
If the bulb does not light up, the fault is in the main instrument display panel. Continue
