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.
The relationship between the ECU and the throttle
position sensor (TPS) is very critical to proper system
operation. If the TPS is faulty, or the mounting position of
the TPS to the throttle body is altered, the TPS must be
re-initialized.
For the purpose of troubleshooting, a known-good ECU
from another Polaris ATV EFI of the same model may be
used without system or engine component damage.
ECU Replacement
1. Remove the retaining screws (2) holding the ECU.
2. With the Ignition turned off, disconnect the wire
harness from the ECU.
3. To install, reverse the procedures, reapply a small
amount of dielectric grease to the connector if
desired. Tighten screws to specification.
ECU Retaining Screws:
