Basic Setting (scan tool function 04): Notes
NOTE:
- The specified values for the "Basic Setting" and "Read Measuring Value Block" functions are described in the respective component test descriptions.
- Disconnecting the battery or the Engine Control Module (ECM) harness connector will erase all learned values and the readiness code. Diagnostic Trouble Code (DTC) memory, however, will not be erased. After reconnecting the battery and/or the ECM, the engine may idle unevenly and there may be some temporary loss of driveablity. If so, let the engine run at idle for a few minutes until the learning process has been completed.
- No learning will take place if a malfunction affecting engine regulation is stored in DTC memory (this does not include sporadic malfunctions).
- Basic settings are established with the engine running.
- In "Basic Setting" display groups 60 or 98, with the engine stopped and the ignition switched on, adaptation of the throttle valve control module -J338- takes place. Adaptation of throttle valve control module -J338- (with "Basic Setting" function 04 and display group 60), see THROTTLE VALVE CONTROL MODULE, ADAPTATION TO ENGINE CONTROL MODULE (ECM) .
- In "Basic Setting" display groups 88 or 99, oxygen sensor control is switched off. This makes it possible to check for malfunctions that may be caused by oxygen sensor control being switched on or off. In the selected display group, press buttons -4- and -8- to switch back and forth between "Read Measuring Value Block" function 08 and "Basic Setting" function 04.
NOTE:
After selecting "Basic Setting" function 04, the ECM takes the following actions:
- EVAP canister purge regulator valve is closed
- A/C compressor is switched off
