id0140f1802400

  Caution
  • To prevent the A/F sensor damage, do not perform the following operation before starting the engine for the first time after the PCM is replaced.
    ― Fully depress and release the accelerator pedal three times repeatedly while depressing the brake pedal with the ignition switch in the ON position.

  Note
  • If the PCM is replaced, always perform each adjustment procedure using the following steps.

STEP | ACTION | PAGE/CONDITION
--- | --- | ---
1 | Perform diesel particulate filter regeneration procedure. Note • If the diesel particulate filter manual regeneration cannot be performed, go to the next step. | (See DIESEL PARTICULATE FILTER REGENERATION [MZR-CD (RF Turbo)].)
2 | Read the PCM configuration data. | (See PCM CONFIGURATION [MZR-CD (RF Turbo)].)
3 | Replace the PCM. Note • When reusing a used PCM, perform the following data reset beforehand. ― Engine oil data reset ― PCM data reset | (See ENGINE OIL DATA RESET [MZR-CD (RF Turbo)].) (See PCM DATA RESET [MZR-CD (RF Turbo)].)
4 | Turn the engine switch on. | –
5 | Write the PCM configuration data. | –
6 | Perform A/F sensor date reset procedure. | (See AIR FUEL RATIO (A/F) SENSOR DATA RESET [MZR-CD (RF Turbo)].)
7 | Perform IMMOBILIZER SYSTEM programming. | (See IMMOBILIZER SYSTEM COMPONENT REPLACEMENT/KEY ADDITION AND CLEARING [WITH ADVANCED KEYLESS SYSTEM].) (See IMMOBILIZER SYSTEM REPROGRAM PROCEDURE [KEYLESS ENTRY SYSTEM].)
8 | Perform after repair procedure. | (See AFTER REPAIR PROCEDURE [MZR-CD (RF Turbo)].)
9 | Turn the engine switch off. | –
10 | Wait for 20 s. | –
11 | Start the engine. | Verify that the MIL does not illuminate.
12 | Turn the engine switch off. | –
13 | Turn the engine switch on (Engine off). | –
14 | Perform KOEO self-test procedure. | (See KOEO/KOER SELF TEST [MZR-CD (RF Turbo)].)
15 | Perform Intake shutter valve/EGR valve initialization procedure. | (See INTAKE SHUTTER VALVE/EGR VALVE INITIALIZATION [MZR-CD (RF Turbo)].)
16 | Perform diesel particulate filter reset procedure. | (See DIESEL PARTICULATE FILTER RESET [MZR-CD (RF Turbo)].)
17 | Turn the engine switch off. | –
18 | Wait for 20 s. | –
19 | Start the engine. | –
20 | Perform KOER self-test procedure. | Warm up until the exhaust gas temperature (EXHTEMP1, EXHTEMP2, EXHTEMP3 PID) is 100 °C {212 °F} or more. (See KOEO/KOER SELF TEST [MZR-CD (RF Turbo)].)
21 | Perform injection amount correction procedure. | Engine coolant temperature 65—95 °C {149—203 °F}. Intake air temperature 15—65 °C {59—149 °F}. Fuel temperature 30—60 °C {86—140 °F}. (See ENGINE TUNE-UP [MZR-CD (RF Turbo)].)
22 | Turn the engine switch off. | –
23 | Wait for 20 s. | –
24 | Start the engine. | –
25 | Perform diesel particulate filter assessment procedure. | Engine coolant temperature 60 °C {140 °F} or more. (See DIESEL PARTICULATE FILTER ASSESSMENT [MZR-CD (RF Turbo)].)
26 | Perform diesel particulate filter regeneration. Caution • If the diesel particulate filter manual regeneration has not been performed in Step 1, perform the diesel particulate filter manual regeneration twice. | (See DIESEL PARTICULATE FILTER REGENERATION [MZR-CD (RF Turbo)].)
27 | Perform repair verification drive mode. | (See OBD DRIVE MODE [MZR-CD (RF Turbo)].)
28 | Verify that O2S11_CAL value is not 0 using the PID O2S11_CAL. ― If the value is 0, return to the previous step. | (See ON-BOARD DIAGNOSTIC TEST [MZR-CD (RF Turbo)].)
29 | Turn the engine switch off. | –
