Inspection and verification
1. Check the validity of the customer's complaint by using the system.
2. Perform a visual inspection for obvious signs of mechanical and electrical damage.
Visual inspection table
|
Mechanical factors |
Electrical factors |
|
– Fuel gauge lock - Damaged fuel tank – Damaged windshield washer fluid reservoir |
– Fuse(s) - Wiring harness – Loose or corroded connector(s) - Instrument panel – Outside air temperature sensor – Information and Message Center – Windscreen washer fluid level switch |
3. If an obvious cause for the reported or received complaint is identified, correct the fault (if possible) before proceeding to the next step.
4. Check the correct operation of the following systems by operating the systems.
- Outside air temperature
- Average speed
- Instantaneous fuel consumption
- Average fuel consumption
- Remaining distance to refueling
5. If the cause of the malfunction is not obvious, check the malfunction symptom and refer to Self-diagnosis Mode.
Self-diagnostic mode
1. To enter the self-diagnosis mode of the information and message center, set the ignition switch to position II, press and hold the SELECT button for five seconds.
2. Release the SELECT button: the information and message center will enter the Self-diagnosis mode.
3. To switch between the tests described below in the Self-Diagnostic Mode, press the SELECT button.
4. To exit the Self-Diagnostic Mode at any time, press the RESET button on the information and message center or the INFO button on the turn signal switch.
5. If Self-Diagnostic Mode is not available, use the FDS 2000 Information and Message Center for diagnostics.

Checked indicator/indicator lamp/display |
Description |
|
1. Checking segments and output tone |
All segments are included |
- |
Displays all the segments that are switched on to check the operation of the bulbs. A tone signal is generated every two seconds. There are no manipulations with the windshield washer fluid level indicator lamp and the ice warning indicator lamp. |
|
2. Checking the inclusion of segments |
All segments are included |
Checking the light bulbs |
Displays all enabled segments to test the operation of the bulbs. |
|
3. Speed sensor input signal status |
km/h or m/h |
Average speed. |
Displays the input pulse signal received from the speed sensor. |
|
4. Fuel supply flow input signal status |

Instantaneous fuel consumption. |
Displays the input pulse signal received from the fuel pump module. |
|
5. Average fuel consumption signal status |
L/100km |
Average fuel consumption. |
Displays the average fuel economy calculated by the powertrain control module (PCM). |
|
6. Fuel tank resistance input signal status |
Fuel pump symbol and L or°G |
Remaining distance to refueling. |
Displays the amount of fuel remaining in the fuel tank in liters or gallons. When the circuit is open, the message OC is displayed; when the circuit is closed, the SC message is issued. |
|
7. Fuel tank resistance input signal status |
Fuel pump |
- |
Displays the fuel tank reference input voltage value in V (the measured level should be 0.5 V below the battery voltage). |
|
8. Fuel correction factor |

9. Air temperature sensor input signal status |
°C |
Outside air temperature. |
Displays the outside air temperature. At values below - 40°C or above + 65°C, the OC and SC messages are displayed. |
|
10. Status of the parking light input signal |
LO or HI |
Status of the input signal of the parking lights |
Displays the status of the parking light input signal. When the parking light is turned on (ON position), HI is displayed. |
|
11. Battery voltage input signal status |
Lbt or Hbt |
Power supply. |
Displays the current battery voltage. The Lbt message is displayed when the battery voltage is low. The Hbt message is displayed when the battery voltage is high. |
|
12. Checking the ROM code |
ROM |
The version of the installed software of the information and messages module. |
Displays the version of the installed software. |
6. If the complaint is not resolved after exiting the Self-Diagnostic Mode, refer to the Malfunction Symptom Table.
