ECM, Adapting to Throttle Valve Control Module
NOTE:- Only Initiate "Basic Setting" Function O4 When The Throttle Valve Control Module -J338-, The Engine Control Module (ECM) -J220- Or The Engine Has Been Replaced.
- Initiating Basic Setting Matches The ECM To The Throttle Valve Control Module With The Ignition Switched On.
- If The Basic Setting Is Interrupted By The ECM, It Can Be, That The Throttle Valve Is Not At The Mechanical Idle Stop Due To Dirt Contamination Or An Incorrectly Adjusted Accelerator Cable. In This Case The Malfunction "Basic Setting Not Performed" Will Be Stored In DTC Memory. Thoroughly Clean The Soiled Area In Throttle Valve Control Module. The Next Time The Ignition Is Switched On, Basic Setting Will Be Automatically Performed Again.
