Turn the ignition switch to ON and turn the Techstream on. 2. Clear DTCs (even if no DTCs are stored, perform the clear DTC operation). 3. Turn the ignition switch off and wait for at least 30 seconds. 4. Turn the ignition switch to ON and turn the Techstream on [A]. 5. Start the engine and wait 2 minutes. 6. 3UR-FE ENGINE CONTROL SYSTEM: SFI SYSTEM: P2237-P2239... |
