Issue:
A customer may experience a hesitation or shudder while driving approximately 30-55 mph and at 14002000 RPM. The engine speed begins to visibly flutter on the tachometer. This occurs during warm up after
a cold start. This hesitation is felt under these conditions while maintaining a constant accelerator pedal
position.
Cause:
An updated PCM calibration is available to resolve this concern
Action:
Ensure that the customer complaint is fully understood & follow all troubleshooting actions as outlined in
the TOPIX Workshop Manual/ Pathfinder Help Text.
If these DTCs (P242B-64 & P246F-64) are stored in isolation or return after diagnosis, use at least
Pathfinder 196 to update the PCM & retest.
CAUTION: This procedure requires a minimum of Pathfinder 196 loaded or later.
NOTE: The Jaguar Land Rover (JLR) approved diagnostic equipment will read the Vehicle Identification
Number (VIN) for the vehicle and automatically take the vehicle out of ‘Transportation mode’ if required.
Connect the JLR approved battery support unit.
Connect the JLR approved diagnostic equipment to the vehicle and begin a new session.
Follow the JLR approved diagnostic equipment prompts.
Select 'ECU Diagnostics'.
Select Powertrain control module [PCM].
Select 'Update ECU'.
Follow all on-screen instructions to complete the task.
If required, reset the vehicle to ‘Transportation mode’.
When all of the tasks are complete, exit the session.
Disconnect the JLR approved diagnostic equipment and the JLR approved battery support unit.
