INFORMATION
1. If the engine switch-off time (formed in the gateway control unit) that is output is > the actual value, the engine seems to have cooled down
insufficiently.
This can be checked by switching the vehicle off - with the engine at operating temperature - for longer than 6 hours (ignition off). After this
time:
- Switch the ignition on and connect the PIWIS Tester.
- Select the following actual values: T020, T030, T040.
- Compare the actual values:
- If the values are close together, the switch-off time calculation is probably incorrect
-->Replace gateway control unit.
- The engine temperature (T020) deviates significantly
-->Check and repair the temperature sensor and wiring
2. Nominal value depending on:
- Time since Ignition off and
- Intake air temperature at Engine start
Example: Nominal value Engine start temperature max. 65 锟斤拷C (锟斤拷F)
- Time since Ignition off 6.1 hour(s) and
- Intake air temperature at Engine start 44 锟斤拷C (锟斤拷F)
