Inspection and verification
1. Check the validity of the customer's complaint by activating the system.
2. Perform a visual check for obvious signs of mechanical and electrical damage.
Visual Inspection Table
|
Mechanical factors |
Electrical Factors |
|
– Blocking the fuel gauge – Damaged fuel tank – Damaged washer fluid reservoir |
- Fuse (And) – wiring harness – Loose or corroded connector (s) - Dashboard – Outside temperature sensor – Information and message center – Windshield washer fluid level switch |
3. If there is an obvious cause for the reported or received complaint, correct the problem (if it is possible) before moving on to the next step.
4. Check the correct operation of the following systems by operating the systems.
- Outside temperature
- average speed
- Instant fuel consumption
- Average fuel consumption
- Remaining distance to refuel
5. If the cause of the problem is not obvious, look for the symptom and refer to the Self-Diagnostic Mode.
Self-diagnosis mode
1. To enter the information and message center self-diagnosis mode, turn 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-diagnostic mode.
3. Press the SELECT button to switch between the tests described below in Self-Diagnostic Mode.
4. To exit Self-Diagnostic Mode at any time, press the Information and Message Center RESET button 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 to diagnose.

Test pointer/indicator/display |
Description |
|
1. Check segments and output tone |
All segments turn on |
- |
Displays all segments that are switched on to check the operation of the bulbs. A tone 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 turn on |
Light Bulb Check |
Displays all segments that are switched on to check the operation of the bulbs. |
|
3. Speed sensor input status |
km/h or m/h |
Average speed. |
Displays the input pulse signal received from the speed sensor. |
|
4. Fuel flow input status |
l/h |
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 consumption calculated by the powertrain control module (PCM). |
|
6. Fuel tank resistance input status |
Fuel pump symbol and L or°G |
Remaining distance to refuel. |
Displays the amount of fuel remaining in the fuel tank in liters or gallons. When the circuit is opened, an OC message is issued; at which the circuit is closed, the message SC is issued. |
|
7. Fuel tank resistance input status |
Fuel pump |
- |
Displays the voltage value of the fuel tank reference input in V. (the measured level should be 0.5 V below the battery voltage). |
|
8. Fuel correction factor |
MPG |
Instant fuel consumption |
Displays the fuel consumption pulse correction factor as a percentage. (can be±25). |
|
9. Air temperature sensor input status |

Outside air temperature. |
Displays the outdoor temperature. Below -40°C or above +65°C, OC and SC messages are displayed. |
|
10. Signal input status of parking lights |
LO or HI |
Side light input status |
Displays the status of the marker lights input. If the marker lights are on (ON position), the message HI is displayed. |
|
11. Battery voltage input 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 |
Version of the installed software of the information and messages module. |
Displays the installed software version. |
6. If the complaint persists after exiting the Self-Diagnostic Mode, refer to the Symptom Table.
