Scheme 646
You are now in diagnostic test mode (DTM) 5.
When the LED is lit the system can accept codes.
- Enter the first digit while the LED is still lit. Do not enter the second digit until the LED is lit again.
- Enter the second code digit when the LED is lit.
- Wait until the LED is lit again and enter the third digit.
- Read off and note response code.
Responses to codes can be read off as text in the following tables.
| Code | Text | Remarks | Response code explanation |
|---|---|---|---|
| 1-1-1 | Odometer | The mileage recorded by the instrument, last three digits. | |
| 1-1-2 | Odometer | The mileage recorded by the instrument, first three digits. | |
| 1-1-3 | Odometer manipulated time | Time in hours that the speedometer has been disabled while the engine has been running. Three last digits of a six digit number. | No code. Flashes correspond to actual numbers, 0 = 10 flashes. |
| 1-1-4 | Odometer manipulated time | Time in hours that the speedometer has been disabled while the engine has been running. Three first digits of a six digit number. | No code. Flashes correspond to actual numbers, 0 = 10 flashes. |
| 1-2-1 | Mileage since last service | Indicates mileage in km or miles since the last service (when the service counter was reset). | See Table 1, 1-2-1 Mileage since last service . |
| 1-2-2 | Time since last service reminder indicator (SRI) reset | Real time in months since last service. | See Table 2, 1-2-2 Time since last service . |
| 1-2-3 | Engine hours since service | Time in hours that the engine has been running since the last service. | See Table 3, 1-2-3 Engine hours since last service . |
| 1-2-4 | Speedometer type | Market specification for combined instrument panel. | See Table 4, 1-2-4 Speedometer . |
| 1-3-1 | The service reminder indicator (SRI)* - mileage parameter | Distance entered for service intervals | See Table 5, 1-3-1 Mileage interval for service reminder indicator (SRI) activation . |
| 1-3-2 | Service reminder indicator (SRI)* - time parameter | Actual time entered for service intervals | See Table 6, 1-3-2 Actual time interval for service reminder indicator (SRI) activation . |
| 1-3-3 | Service reminder indicator (SRI)* - engine hours parameter | Engine hours entered for service intervals. | See Table 7, 1-3-3 Engine hours interval for service reminder indicator (SRI) activation . |
| 1-3-4 | Tachometer type | Engine speed (RPM) entered | See Table 8, 1-3-4 Tachometer, adjusting engine speed (RPM) reading . |
Information and check
Diagnostic test mode (DTM) 6 - Data entry
Diagnostic test mode (DTM) 6 is used when replacing the combined instrument panel.
Note. When replacing the combined instrument panel check the following data and if necessary program it into the new combined instrument panel.
- 1) Speedometer calibration code (selecting speedometer type).
- 2) Mileage. The mileage from the old combined instrument panel must be transferred.
- 3) Criteria for service reminder indicator (SRI) activation are always programmed and should only be reprogrammed if another service reminder indicator (SRI) parameter is required.
Note. This programming can only be carried out once for each instrument. It is important to do it correctly. Use a text readout unit if possible.
Go into diagnostic test mode (DTM) 6
- Press the button five times, briefly but distinctly within 30 seconds of the response code being flashed out as above. You are now in diagnostic test mode (DTM) 6.
- Wait until the LED is lit.
- Enter the new code according to one of the tables. «Tables 1-8»(ref-408443-S17806238902011071200000) .
- One digit at a time.
Wait for the LED to light between each digit.
- Confirm what you have entered.
The control module flashes out the same code that was entered to allow you to check that you entered the correct code (if you have made a mistake start from the beginning).
Wait until the LED is lit again.
- To confirm that the code is correct depress the button for five seconds or more.
- Release the button and the lamp will go out.

DTM 1 - Self-test
The microprocessor in the dashboard can store up to 7 different kinds of fault.
The control module has a memory for DTCs. This memory retains the DTCs even if the battery is disconnected for any length of time.
Use this DTM to find out if some input signals to the dashboard are missing or if the speed data signal leads are faulty. Speed data is something the dashboard sends to a large number of other systems, such as the trip computer, cruise control, fuel and ignition system and automatic gearbox.
