Diagnostic Mode 01 - Read Current System Data

Diagnostic Mode 01 - Read Current System Data

Diagnostic Mode 01 makes it possible to access current emissions-related measured values and diagnostic data. The original measured values (no replacement values), input and output data and system status information are displayed using Diagnostic Mode 1.

Test requirement
- Coolant temperature at least 80 degrees C.

Procedure
- Connect the scan tool.
- Start the engine and run at idle.
- Select "Diagnostic Mode 1: Obtain data".
- From the following table, select the desired the "PID" that is to be monitored, e.g. "PID 05-Coolant temperature".

NOTE: More than one "PID" may be selected and monitored.

The current values of the component or system that is being monitored will be displayed on the scan tool screen.

PID Component or System
04: Calculated load condition value
05: Coolant temperature
06: Oxygen integrator, bank 1
07: Oxygen adaptation value, bank 1
09: Oxygen adaptation value, bank 2
12: Engine RPM
13: Vehicle speed
14: Ignition timing adjustment at 1. cyl. in direction
15: Intake air temperature (IAT)
16: Air flow quantity at Mass Air Flow (MAF) sensor
17: Throttle valve position (absolute)
18: Secondary air injection (AIR)
19: Oxygen sensor location
21: Sensor voltage Bank 1 Sensor 2
25: Sensor voltage Bank 2 Sensor 2
28: OBD request is designed for diagnostic of this vehicle
33: Driven distance after MIL on
52: Oxygen sensor value Bank 1 - sensor 1
56: Oxygen sensor value Bank 2- sensor 1

- Switch the ignition off.

End of diagnosis.
