Necessary Action
Turn the key switch to the OFF position, wait
several seconds, turn the key switch to the ON
position, and check for normal vehicle operation.
If this fault continues to occur, inspect traction
motor encoder (speed sensor) (see Traction
Motor in this section).
Also, inspect the circuit wires between the
traction motor encoder and the controller (see
Electrical Schematic and Wire Harness
Drawings in Chapter 6 -- Electrical Drawings).
If a traction motor armature problem exists in the
motor (e.g. worn bearing in rear end bracket,
missing retaining ring on rear of armature shaft,
loose or damaged tone ring on armature), an
encoder fault could be generated due to the
armature issue.
Turn the key switch to the OFF position, wait
several seconds, turn the key switch to the ON
position, and check for normal vehicle operation.
If this fault continues to occur, contact your
