PC816 – 2022 PATHFINDER
ISS ECM REPROGRAM

SERVICE PROCEDURE:
Reprogram the ECM
IMPORTANT: Before starting, make sure:


ASIST on the CONSULT PC has been synchronized (updated) to the current date



All CONSULT-III plus (C-III plus) software updates (if any) have been installed



The CONSULT PC is connected to the Internet (Wi-Fi or cable)

NOTE:


Most instructions for reprogramming with CONSULT-III plus (C-III plus) are
displayed on the CONSULT PC screen



Take the vehicle for a 10 minute drive in order to meet the following Idle Air
Volume Learn (IAVL) conditions:
 Engine coolant temperature: 70 -100°C
(158 - 212°F)
 Battery voltage: More than 12.9V (At
idle)
 Transmission: Warmed up



After reprogramming is complete, you will
be required to perform Throttle Valve
Closed Position, Idle Air Volume Learn,
Accelerator Closed Position, and DTC erase



Connect a battery maintainer or smart charger to the 12V battery. If the
vehicle battery voltage drops below 12.0V or above 15.5V during
reprogramming, the ECM may be damaged.



Be sure to turn OFF all vehicle electrical loads. If a vehicle electrical load
remains ON, the ECM may be damaged.



Be sure to connect the AC Adapter.



If the CONSULT PC battery voltage drops during reprogramming, the process
will be interrupted and the ECM may be damaged.



Turn OFF all external Bluetooth® devices (e.g., cell phones, printers, etc.)
within range of the CONSULT PC and the plus VI. If Bluetooth® signal waves
are within range of the CONSULT PC or the plus VI during reprogramming,
reprogramming may be interrupted and the ECM may be damaged.

1. Verify the extended storage switch is pushed IN (Figure 1).
