1. DTC

description:

DTC P099E High current of electromagnetic valveS8 (short circuit)

DTC P099F electromagnetic valveS8low current(open circuit)

The transmission control unit (TCU) uses a variable pressure electromagnetic valve to regulate the hydraulic
pressure. The hydraulic system controls the clutch in the transmission to realize the torque transmission.

The transmission control unit (TCU) can control a certain amount of pressure by adjusting the current of the
electromagnetic valve to enter the clutch and the transmission of the clutch torque is directly related to the current
of the electromagnetic valve.

During operation, the transmission control unit evaluates the current actually delivered to the electromagnetic
valve and compares with the expected. If there is no pre-defined parameter currently, the DTC is set to display
abnormal load of the transmission control unit.

4. Diagnostic

Procedures:

Note: Before carrying out this diagnosis step, observe the data list on fault diagnosis tester and analyze the
accuracy of the data, as these will help with quick diagnosis.

1

Read the fault code again after clearing away the fault code to Check if fault codes, except DTC
P099E and P099F exist in the control system.

A. Connect fault diagnosis tester to the datalink connector.

B. Rotated ignition switch to ON position

C. Switch on fault diagnostic device power supply

D. Clear DTC code.

E. Reset reading fault code, and check if DTCs meet setting condition of fault code in current
