A normal function of the Transmission Control Module (TCM) programming is to perform an internal check that verifies the integrity of the RAM memory allocations.

The DTC P0601 sets when the Random Access Memory(RAM) is not operating correctly when checked on initialization. An area of RAM is failed a read/ write test.

A normal function of the Transmission Control Module (TCM) programming is to perform an internal check that verifies the integrity of the KAM memory allocations.

The DTC P0603 sets when the keep alive memory (KAM) is not operating correctly when checked on initialization.

An area of KAM is failed a read/ write test.

A normal function of the Transmission Control Module (TCM) programming is to perform an internal check that verifies the integrity of the RAM memory allocations.

The DTC P0604 sets when the Random Access Memory(RAM) is not operating correctly when checked on initialization. An area of RAM is failed a read/ write test.

A normal function of the Transmission Control Module (TCM) programming is to perform an internal check that verifies the integrity of the RAM memory allocations.

The DTC P1604 sets when the Random Access Memory(RAM) is not operating correctly when checked on initialization. An area of RAM is failed a read/ write test.

The Malfunction Indicator Lamp(MIL) will illuminate.

The MIL will turn OFF when the malfunction has not occurred after three-ignition cycle.

A history DTC will clear after 40 consecutive warm up cycles without a fault.

Using a scan tool can clear history DTCs.

In case that TCM reset has been occured by software (warm reset) not by ignition key ON, TCM increments software reset counter. If the counter exceeds the permissible maximum value for the software count then the fault will be detected.

The external watchdog will be triggered. If the external warchdog does not run out after 30ms then the fault will be detected.

The brake switch is used to indicate brake pedal status to the transaxle control module(TCM). The brake switch is a normally open switch. Applying the brake pedal closes the switch, supplying voltage to the TCM. Releasing the brake pedal interrupts voltage to the TCM.

This error is set with status status flag static at the system initialization phase. After that if the debaunced brake light switch signal is active in the TCM run mode then the failure statue is set to sporadic. In this case the fault isn't deluded but it is suppressed in keyword service.

The neutral start switch is located on the selector shaft and informs the TCM of the current selector lever position P-R-N-D-3-2-1.

The selector lever position is transmitted to the TCM in encoded form along 4 lines. The encoding is such that malfunctions in the connecting lead are identified.

The neutral start switch is located on the selector shaft, which is connected to the selector lever via a pull cable. In addition, the neutral start switch controls the starter interlock, the reversing light and the selector lever position indicator on the instrument panel.

The TFT sensor is a positive temperature coefficient thermistor (temperature sensitive resistor)that provides information to the TCM regarding transaxle fluid temperature. The temperature sensor is located in valve body. Calculated temperature is a factor to determine at the shift time and shift delay time.

The internal electrical resistance of the sensor varies in relation to the operating temperature of the transaxle fluid.

The TCM sends a 5volt-reference signal to the temperature sensor and measures the voltage rise in the electrical circuit. A higher fluid temperature creates a higher resistance in the temperature sensor, thereby measuring a lower voltage signal.

The TCM measures this voltage as another input to help control line pressure, shift schedules and LOC apply. When transaxle fluid temperature reaches 120°C (248°F) the TCM enters "hot mode." Above this temperature the TCM modifies transaxle shift schedules and LOC apply in an attempt to reduce fluid temperature by reducing transaxle heat generation.

Information relative to transaxle input speed to the TCM. The TCM uses transaxle input speed information to control line pressure, LOC apply and release and transaxle shift patterns. This information is also uses to calculate the appropriate operating gear ratios and LOC slippage.

The input speed sensor mounts onto piston B that is inside of valve body.

An air gap of 1.8~2.2mm(0.07~0.086inch) is maintained between the sensor and the piston B.

The sensor consists of a permanent magnet surround by a coil of wire. As the piston B is driven by the turbine shaft, an AC signal induced in the input speed sensor. Higher vehicle speeds induce a higher frequency and voltage measurement at the sensor.

Sensor resistance should measure between 825~835 ohms at 20°C(68°F). Sensor can measure from 1,000~ 8,000HZ.
