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