PRIOR TO ECU REMOVAL OR AFTER INSTALLATION OF THE CHIP TUNING DPF SIMULATOR OR CHIP TUNING DPF REMAPPING
PRIOR TO ECU REMOVAL/REPLACEMENT OR FITTING DPF SIMULATOR
Before we can complete an ECU DPF removal successfully, you the customer, must ensure there are no DPF codes & no DPF lights on at time of ECU removal and conduct a DPF REGEN.
If the ECU has already been removed these steps must be completed when the ECU is reinstalled as failure to do these will cause engine check lights. There is no other way to do these steps except with a high-end Diagnostic Tool that has “SPECIAL FUNCTIONS” feature on the menu tree. A good mechanic or the Dealer will have the Scan Tool to be able to do these steps.
To conduct the RESET PROCEDURE, do the following step by step:
Plug in Scan tool
Key ON, Engine OFF and use the Scan Tool & ensure ALL DPF codes are cleared & that they do not return.
Find & rectify faults (electrical issues, sensor failures etc), if any, causing sensor codes to stay on.
Once cleared, you may notice no codes but DPF light on. This can mean a blocked DPF or DPF regeneration is due, which will simply show the light but no code. This is OK.
To clear the DPF light, use the Scan Tool & run ALL DPF regeneration protocols that exist. (4 protocols or more on Mitsubishi, Isuzu has 1 DPF Data Reset and 1x Oil Counter Reset)
Once resets have been completed, Cycle IGN OFF and ON (engine OFF) and scan for codes again and erase codes. Confirm the DPF light is off. DO NOT START ENGINE AFTER THIS STEP.
Now that you have NO CODES & NO DPF LIGHT with IGN “ON” (engine OFF) Switch off IGN
DO NOT START ENGINE!!!
DISCONNECT THE NEGATIVE TERMINAL FROM THE BATTERY.
Remove ECU & send to Chip Tuning with the 3 forms that are on the website under “DPF Removal”.
After you receive the ECU back from us, and before refitting the ECU, make sure the battery is STILL disconnected.
Refit ECU. Re-connect battery & turn IGN “ON”. With a high-end Scan Tool, clear all codes in ALL Control Modules (NOT JUST THE ENGINE CONTROL MODULE). Use, the “ERASE CODES” function on your Scan Tool REGARDLESS of whether or not any codes present. eg: Mitsubishis can hide some random codes after the ECU has been disconnected even when no codes display. So clear all again.
Start engine and test drive vehicle for approx. 1 km, stop and turn steering wheel to extreme left and right. This will reset the Steering Angle Sensor.
