Malfunction Threshold

The measured current for the PCM's command value is as specified here for at least 1 second.

MALFUNCTION THRESHOLD VALUE

Diagnosis Details

Conditions for illuminating the MIL

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the
PCM memory.

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic
runs.

The MIL, the DTC, and the freeze frame data can be cleared by using the scan tool Clear command or by
disconnecting the battery.

General Description

A/T clutch pressure control solenoid valve C is used for clutch pressure control. A spool in A/T clutch pressure
control solenoid valve C pushes a valve according to the duty cycle that is controlled by the powertrain control
module (PCM) to pressurize fluid so the hydraulic pressure is proportional to the current. The PCM measures
the current flowing through A/T clutch pressure control solenoid valve C and uses feedback control to
compensate the difference between the actual current and the commanded one. If the measured current for the
PCM output duty cycle is not within a specified range (open or short), a malfunction is detected and a DTC is
stored.

Fig. 161: Shift Solenoid Valve A Circuit Diagram

Fig. 162: Shift Solenoid Valve Driving Signal Combination Table

General Description

When shift solenoid valves A, B, C, D, and E are turned ON, the hydraulic pressure circuit opens. The hydraulic
pressure circuit supplies/discharges hydraulic pressure to/from each clutch according to the combination of the
ON/OFF status of those valves and the shift valves. The powertrain control module (PCM) commands the
driver circuit to turn on the shift solenoid valve. The circuit diagnoses malfunctions such as a circuit short or
open, and sends back a return signal during the PCM's command. When the return signal does not match the
PCM command, a malfunction is detected by the PCM. The malfunction is detected when the return signal does
not match the PCM command to turn ON the shift solenoid valve, and a DTC is stored.
