VOLUNTARY SERVICE CAMPAIGN
2018 PATHFINDER; ELECTRIC INTAKE VALVE TIMING
CONTROL MODULE REPROGRAMMING
CAMPAIGN ID #:
APPLIED VEHICLES:
PC661
2018 Pathfinder (R52)
Check Service COMM or Dealer Business Systems (DBS)
National Service History to confirm campaign eligibility.
INTRODUCTION
Nissan is conducting this voluntary service campaign on certain specific 2018 model year
Pathfinder vehicles to reprogram the electric Intake Valve Timing (IVT) control module. This
service will be performed at no charge to the customer for parts or labor.
IDENTIFICATION NUMBER
Nissan has assigned identification number PC661 to this campaign. This number must
appear on all communication and documentation of any nature dealing with this campaign.
DEALER RESPONSIBILITY
Dealers are to repair vehicles falling within range of this campaign that enter the service
department. This includes vehicles purchased from private parties, vehicles presented by
transient (tourists) owners, and vehicles in a dealer’s inventory.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job
properly and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO
NOT assume that it does. See your Nissan dealer to determine if this applies to your vehicle.

19. Compare the “Software Version detected” to the “Software Version available.”

If the “Software Version detected” is THE SAME as the “Software Version available”
then reprogramming IS NOT required, skip to step 24.

If the “Software Version detected” is DIFFERENT than “Software Version available”
then reprogramming IS required, continue to the next step (step 20).
NOTE: The “Software Version detected” will be different than the “Software Version
available” if reprogramming is required.

ERROR SCREENS
If an error should occur, refer to the following pages for possible causes.
The error in Figure 19 indicates that eVTC reprogramming tool (J-52601) has a poor USB
connection.
a. Inspect the USB connection on the CONSULT PC and the eVTC Reprogramming
tool (J-52601).
b. If the connections are secure, try a known good mini USB cable and retry
reprogramming.

The error in Figure 20 indicates that eVTC Reprogramming tool (J-52601) has a poor
reprogramming harness connection.
a. Inspect the round connector at the eVTC Reprogramming tool (J-52601).
b. Inspect connector A and B on the electric IVT control module.
c. If the connections are secure, try a known good reprogramming harness.
