Official summary
Some vehicles without i-ACTIVSENSE may exhibit that the i-ACTIVSENSE OFF symbol turns on in the instrument cluster after replacing the speedometer. Since vehicles without i-ACTIVSENSE do not have an i-ACTIVSENSE switch, there is no way to clear the i-ACTIVSENSE OFF symbol. This is caused by a communication error between the new speedometer and the vehicle control module (VCM) due to a software level difference.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
