<Vehicles without rear differential lock system>
Code No. 26 Center differential lock switch system
Probable cause
Code No. 27 Rear differential lock switch system
The ABS-ECU is designed to accommodate the fitting of a rear differential lock.
Because of this, for vehicles which are not equipped with a rear differential lock,
system voltage is applied to terminal (33) of the ABS-ECU instead of the rear
differential lock switch signal. If there is an open circuit in the lines by which this
system voltage is applied, the ABS-ECU outputs code Nos. 26 and 27.
