1.
Repair or replacement. 2.
Turn the ignition switch to ON. 3.
Drive the vehicle at 54 km/h (34 mph) or more for 3 seconds or more to clear the warning lights. |
Check the rear speed sensor.
The rear speed sensor tip is free of oil and foreign matter.
If foreign matter of 1 mm (0.03937 in.) x 1 mm (0.03937 in.) or more is adhered to the rear speed sensor, this DTC may be stored.
