Diagnostic Mode 6: Check Tests Of Parts Not Contantly Monitored



Diagnostic Mode 6: Check Test Results Of Components That Are Not Continuously Monitored

Function
This diagnostic mode displays the test results of emission relevant components and systems which are not continuously monitored.

The values of the individual test results must reach the specified value or must be within the min.- and max.- limits.

Test-ID Component, System
09: Coolant temperature plausibility
10: Start-Stop positions test of quantity adjuster
11: Fuel temperature plausibility
12: Plausibility test of Manifold Absolute Pressure (MAP)/Barometric Pressure

Test-ID 09: Coolant temperature plausibility

Test requirements
- There must not be any DTCs stored in DTC memory, Diagnostic mode 3: Check DTC memory. Diagnostic Mode 7: Check Tests Of Parts Constantly Monitored
- Coolant temperature must not be above the maximum of 20 degree C, Diagnostic mode 1: Check measuring values; PID 5, Coolant temperature. Diagnostic Mode 1: Check Measured Values
