Diagnostic mode 1: Check measured values

Requirement
- Coolant temperature must be at least 80 degree C, see PID 5, Coolant temperature.

Procedure
- Connect diagnostic tester. Diagnostic Tester, Connecting
- Depending on the desired operating condition:switch on ignition
or
- Start engine and let run at idle.
- Under address word 33, select "Diagnostic mode 1: Checking measured values."
- Select the desired measured values "PID XX".

NOTE:
- The specified values for the respective measuring values can be found at the respective component-and function tests.
- The following list only serves as an overview.
- The measuring values are sorted according to the PID (parameter-identifications).

01: Monitoring status since erasing DTC memory
03: Condition of the fuel system
04: Calculated load condition value
05: Cooling fluid temperature
06: Short time gasoline-air ratio bank 1
07: Gasoline-air ratio bank 1
12: Engine rotations per minute (RPM)
13: Vehicle speed
14: Valve timing adjustment at 1. cyl. to "advance"
15: Intake Air Temperature (IAT)
16: Air flow quantity at Mass Air Flow (MAF) sensor
17: Throttle valve position (absolute)
18: Availability status of secondary air
21: Bank 1 - sensor 2
