DETAILED FLOW
1.
COLLECT THE INFORMATION FROM THE CUSTOMER
It is also important to clarify customer complaints before inspection. First of all, reproduce symptoms, and
understand them fully. Ask customer about his/her complaints carefully. In some cases, it will be necessary to
check symptoms by driving vehicle with customer.
CAUTION:
Customers are not professional. It is dangerous to make an easy guess like “maybe the customer
means that...,” or “maybe the customer mentions this symptom”.

System Description
INFOID:0000000000957227
DESCRIPTION
• Electronic control allows optimal distribution of torque to front/rear wheels to match road conditions.
• Makes possible stable driving, with no wheel spin, on snowy roads or other slippery surfaces.
• On roads which do not require AWD, it contributes to improved fuel economy by driving in conditions close to
rear-wheel drive.
• Sensor inputs determine the vehicle's turning condition, and in response tight cornering/braking are con-
trolled by distributing optimum torque to front wheels.
• It transmits/receives each signal from the following control unit via CAN communication line.
NOTE:
• When driving, if there is a large difference between front and rear wheel speed which continues for a long
time, fluid temperature of drive system parts becomes too high and AWD warning lamp blinks quickly. (When
AWD warning lamp blinks, vehicle changes to rear-wheel drive conditions.) Also, optional distribution of
torque sometimes becomes rigid before lamp blinks quickly, but it is not malfunction.
• If AWD warning lamp is blinking quickly, stop vehicle and allow it to idle for some time. Blinking will stop and
AWD system will be restored.
