Temperature gauge (MIU 1)
| Temperature gauge (MIU 1) |
| Fault symptoms |
Temperature gauge always indicates low temperature, L Diagnostic trouble code B1311 may be present in ICE module Radiator fan may start when ignition switched on
| Diagnostic procedure |
| 1. |
Check whether any diagnostic
trouble codes are present in the ICE module. If there are, take the necessary steps.
|
|
| 2. |
If there are no diagnostic trouble codes in ICE, continue fault diagnosis as
described under "Electrical system, ICE"
.
If no faults are discovered when carrying out the diagnostic procedure described, continue with point 3. |
|
| 3. |
Check the conductive foil on the rear of the main instrument display panel for an
open circuit between pin 4 (12p-1) and the screw marked "T-SIG" on the main instrument
display panel. If the conductive foil is intact and the temperature gauge does not work, the
fault is probably in the instrument. The complete main instrument display panel will have to be
changed. If there is an open circuit in the conductive foil, change the foil.
