(ECM)
The ECM is located beneath the passenger seat near the
battery.
NOTE: The ECM is only serviceable as an assembly.

The ECM is rarely the cause for electrical problems;
however, if the ECM is suspected, substitute another
ECM to verify the suspected one is defective.
This system has a built-in feature that will only allow an
ECM of the same part number to be used in this model.
Do not attempt to substitute an ECM from a different
model as the system will not allow it to start.
Error codes can be cleared by following the procedures
located in the Gauge Diagnostic Menu sub-section in this
section.
