MANUAL TRANSMISSION TROUBLESHOOTING225
Code No.25 Abnormal tyre diameterAssumed cause of concern
Abnormal tyre Code No. 25 is output in cases where, when
the steering wheel is in a central position, and vehicle speed
is 20kph or more, there is a discrepancy between one of the
vehicle wheel speed sensors and the average of the 4 wheel
speed sensors, in that it is outside the specified range.However, the warning lamp does not come on.• Tyre malfunction
•Vehicle speed sensor malfunction
• Rotor malfunction
• Wheel bearing malfunction
• Harness, connector malfunction

Remarks*1: refer to ’005 Lancer Sedia Service Manual (No.1036K00)*2: refer to ’011 Lancer Evolution VII Service Manual (No.1036K02)
