NOTE: If no active codes are present on the LCD or
verified through the Dealer Diagnostic Service and the
vehicle is experiencing steering-related issues, there
may be a mechanical steering-related issue. In this
case, the EPS is not the cause of the issue. Components
that may contribute to this type of issue could be
abnormal tire wear, bad wheel bearings, ball joints, tie
rod ends, tie rods, or bushings. Check the complete
steering system for any sign of wear or misalignment.
NOTE: If any codes are active and verified with the
Dealer Diagnostic Service, EPS replacement is not
always necessary. Follow the instructions listed in the
chart to potentially correct the malfunction.
* After correcting condition, cycle key switch On-Off-On.

has been detected.
EPS reflash has failed. Battery power was lost, or
the key switch was turned off, during EPS reflash
programming
EPS must be reprogrammed

has been detected.
Intermittent power has prevented a successful
application code launch.
Correct EPS power condition*
C1320 Incorrect Vehicle
Speed-to-RPM Ratio

signal less than 500 RPM.
Intermittent or broken main harness RPM wires,
intermittent voltage regulator, intermittent or
broken ACG stator wires.
Correct EPS condition*
C1321 Vehicle Speed Erratic
