WARNING: This page is about a different car, the 2004 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

This is not an OBD-II self-diagnostic item.
Diagnostic trouble code "VEH SPD SE/CIR-MTR" with Consult-II or 15th judgement flicker without Consult-II is detected when TCM does not receive the proper vehicle speed sensor MTR signal (input by CAN communication) from unified meter and A/C amp.
