April 5, 2026: LEMON Manuals is launched! Read the announcement.

DTC C0210/33 Rear Speed Sensor RH Circuit; DTC C0215/34 Rear Speed Sensor LH Circuit; DTC C1273/73 Low Output Signal of Rear Speed Sensor RH (Test Mode DTC); DTC C1274/74 Low Output Signal of Rear Speed Sensor LH (Test Mode DTC): Description

Refer to DTC C0200/31 AND C0205/32  .

DTCs C1273/73 and C1274/74 can be deleted when the speed sensor sends a vehicle speed signal or the Test Mode ends. DTCs C1273/73 and C1274/74 are output only in the Test Mode.
