ECU Service
Never attempt to disassemble the ECU. It is sealed to
prevent damage to internal components. Warranty is void
if the case is opened or tampered with in any way.
All operating and control functions within the ECU are
pre-set. No internal servicing or readjustment may be
performed. If a problem is encountered, and you
determine the ECU to be faulty, contact the Polaris
Service Department for specific handling instructions. Do
not replace the ECU without factory authorization.
For the purpose of troubleshooting, a known-good ECU
from another Polaris RZR XP 1000 of the same model
may be used without system or engine component
damage.
ECU Replacement
Although the need for ECU replacement is unlikely, a
specific replacement procedure is required to ensure that
all essential data contained within the original ECU is
transferred to the replacement ECU.
NOTE: Refer to this procedure and carefully follow
all instructions provided in Digital Wrench®.
1. Carefully follow the ECU replacement instructions
provided in Digital Wrench® to ensure that all
essential data contained within the original ECU is
transferred to the replacement ECU.
2. Remove the black plastic cover by lifting up on the
tab. Remove the retaining screw that attaches the
ECU to the left rear fender well.
3. With the ignition turned off, disconnect the wire
harness from the ECU. Lift the connector locking
lever and rotate it up until the connector is free from
the ECU.
NOTE: Upon removing the ECU connector, you
should hear a “click” when the connector is fully
open.
4. To install, reverse the procedure and tighten the
mounting screws to specification.
NOTE: Upon installing the ECU connector, you
should hear a “click” when the connector is fully
closed.
