Tight corner braking<\/p>\n<\/th>\n<\/tr>\n<\/thead>\n

\n
Description<\/span><\/div>\n<\/td>\n
\n
\u2022 Brakes seem to be applied during tight cornering while driving very slowly on paved road.<\/div>\n<\/td>\n<\/tr>\n
\n
Possible cause<\/span><\/div>\n<\/td>\n
\n
\u2022 Because the coupling component locks up easily (similar to direct AWD), rotational difference between the front and rear wheels cannot be absorbed and brake-like phenomenon occurs.<\/div>\n
\u2022 Due to the coupling component construction, slight tight corner braking effect occurs during tight cornering on a paved road. (AWD system is normal. Compare with another same model vehicle to determine malfunction.)<\/div>\n

\n
Adjust tire air pressure, then go to next step.<\/div>\n<\/td>\n<\/tr>\n
\n
3<\/div>\n<\/td>\n
\n
INSPECT ABS WHEEL-SPEED SENSOR<\/div>\n
\u2022 Inspect ABS wheel-speed sensor. (See FRONT ABS WHEEL-SPEED SENSOR INSPECTION<\/a>.) (See REAR ABS WHEEL-SPEED SENSOR INSPECTION [AWD]<\/a>.)<\/div>\n
\u2022 Is it normal?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Go to next step.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Repair or replace the malfunctioning location and perform the repair completion verification.<\/div>\n
(See FRONT ABS WHEEL-SPEED SENSOR REMOVAL\/INSTALLATION<\/a>.)<\/div>\n
(See REAR ABS WHEEL-SPEED SENSOR REMOVAL\/INSTALLATION<\/a>.)<\/div>\n<\/td>\n<\/tr>\n
\n
4<\/div>\n<\/td>\n
\n
COMPARE WITH SAME MODEL VEHICLE<\/div>\n
\u2022 Perform simulation driving with another same model vehicle.<\/div>\n
\u2022 Does malfunction recur on the same model vehicle?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
i-ACTIV AWD system is normal.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Go to next step.<\/div>\n<\/td>\n<\/tr>\n
\n
5<\/div>\n<\/td>\n
\n
TRY TO REPRODUCE MALFUNCTION BY DRIVING VEHICLE WITH AWD SOLENOID CONNECTOR DISCONNECTED<\/div>\n
\u2022 Switch the ignition off.<\/div>\n
\u2022 Disconnect the AWD solenoid connector.<\/div>\n
\u2022 Try to reproduce the malfunction by driving the vehicle.<\/div>\n
\u2022 Does the malfunction recur?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n

\n
INSPECT AWD SOLENOID<\/div>\n
\u2022 Inspect AWD solenoid. (See AWD SOLENOID INSPECTION<\/a>.)<\/div>\n
\u2022 Is AWD solenoid normal?<\/div>\n<\/td>\n
\n
Yes<\/div>\n<\/td>\n
\n
Inspect harness between AWD solenoid and electrical supply unit (ESU), then go to next step.<\/div>\n<\/td>\n<\/tr>\n
\n
No<\/div>\n<\/td>\n
\n
Repair or replace the malfunctioning location and perform the repair completion verification.<\/div>\n
