Monitor description

Description of what the ECM monitors and how it detects malfunctions (monitoring purpose and its details).

Related DTCs

A group of diagnostic trouble codes that are output by the ECM based on the same malfunction detection

logic.

Preconditions that allow the ECM to detect malfunctions.

Typical enabling conditions

With all preconditions satisfied, the ECM sets the DTC when the monitored value(s) exceeds the

malfunction threshold(s).

The priority order that is applied to monitoring, if multiple sensors and components are used to detect the

Sequence of operation

malfunction.

While one sensor is being monitored, the next sensor or component is not monitored until the current

monitoring is concluded.

Required sensor/components

The sensors and components that are used by the ECM to detect malfunctions.

The number of times that the ECM checks for malfunctions per driving cycle.

Frequency of operation

«Once per driving cycle» means that the ECM detects malfunctions only one time during a single driving

cycle.

«Continuous» means that the ECM detects malfunctions every time the enabling conditions are met.

Duration

The minimum time that the ECM must sense a continuous deviation in the monitored value(s) before

setting a DTC. This timing begins when the typical enabling conditions are met.

Malfunction thresholds

Beyond this value, the ECM concludes that there is a malfunction and sets a DTC.

MIL illumination timing after a defect is detected.

«Immediate» means that the ECM illuminates the MIL the instant the ECM determines that there is a

MIL operation

malfunction.

«2 driving cycle» means that the ECM illuminates the MIL if the same malfunction is detected again in the

next driving cycle.

Normal operating ranges of sensors and solenoids under normal driving conditions.

Component operating range

Use these ranges as references.

They cannot be used to judge if a sensor or solenoid is defective or not.

1.

PROBLEM SYMPTOM CONFIRMATION

(a) Based on the result of the customer problem

analysis, try to reproduce the symptoms. If the

problem is that the transaxle does not shift up, shift

down, or the shift point is too high or too low,

conduct the following road test referring to the

automatic shift schedule and simulate the problem

symptoms.

2.

PERFORM ROAD TEST

NOTICE:

Perform the test at the ATF (Automatic Transmission

Fluid) temperature 50° to 80 °C (122° to 176 °F) in the

normal operation.

(a) D position test

Shift into the D position, fully depress the

accelerator pedal and check the following points.

(1) Check up-shift operation.

Check that 1st to 2nd, 2nd to 3rd and 3rd to 4th

up-shifts take place, and that the shift points

conform to the automatic shift schedule (See

page SS-19).

HINT:

4th Gear Up-shift Prohibition Control

• Engine coolant temperature is 60 °C (140 °F)

or less.

• ATF temperature is 10 °C (50 °F) or less.

4th Gear Lock-up Prohibition Control

• Brake pedal is depressed.

• Accelerator pedal is released.

AX

• Engine coolant temperature is 60 °C (140 °F)

AX–12

U340E AUTOMATIC TRANSAXLE – AUTOMATIC TRANSAXLE SYSTEM

(4) Check kick-down operation.

Check the possible kick-down vehicle speeds

when the 2nd to 1st, 3rd to 2nd and 4th to 3rd

kick-downs take place while driving with the shift

lever in the D position. Confirm that each takes

place within the applicable vehicle speed range

indicated in the automatic shift schedule (See

page SS-19).

(5) Check for abnormal shock and slippage during

kick-down.

(6) Check the lock-up mechanism.

• Drive in the D position (4th gear) at a

constant speed (lock-up ON) of

approximately 37 mph (60 km/h).

• Lightly depress the accelerator pedal and

check that the engine speed does not change

abruptly.

HINT:

• There is no lock-up function in the 1st, 2nd

and 3rd gears in the D position.

• If there is a sudden increase in engine speed,

lock-up has not occurred.

(b)

3 position test

Shift into the 3 position, fully depress the accelerator

pedal and check the following points:

(1) Check the transmission control switch operation.

While driving in the D position (4th gear), shift

the shift lever into the 3 position, and check that

the 4th to 3rd down-shift takes place.

(2) Check up-shift operation.

Check that the 1st to 2nd and 2nd to 3rd up-

AX

shifts take place, and that the shift points

conform to the automatic shift schedule (See

page SS-19).

HINT:

There is no 3rd to 4th up-shift in the 3 position.

(3) Check engine braking.

While driving in the 3 position and 3rd gear,

release the accelerator pedal and check the

engine braking effect.

(c)

2 position test

Shift into the 2 position and fully depress the

Test Result

Possible Cause

• Line pressure is too low

D range time lag exceeds standard value

• Forward clutch (C1) is worn

• No. 2 one-way clutch (F2) is not operating properly

• Line pressure is too low

R range time lag exceeds standard value

NOTICE:

AX

•

Perform the test at the normal operating ATF

• The line pressure test must always be carried

out by pairs of technicians. One technician

G024063E02

must observe the condition of the wheels and

wheel stoppers outside the vehicle, while the

other is performing the test.

DTCs prescribed by SAE J2012 are recorded in the

ECM memory (See page AX-32).

FI00534

If the malfunction does not occur in 3 consecutive

trips, the MIL goes off but the DTCs remain in the

ECM memory.

(c)

To check the DTCs, connect the intelligent tester to

Intelligent Tester

the DLC3 of the vehicle. The intelligent tester also

enables you to erase the DTCs and check freeze

frame data and various forms of engine data (For

operating instructions, see the instruction book).

(d)

The DTCs include SAE controlled codes and

manufacturer controlled codes. SAE controlled

DLC3

CAN VIM

codes must be set as prescribed by the SAE, while

manufacturer controlled codes can be set freely by

AX

C115104E01

the manufacturer within the prescribed limits (See

(e)

page AX-32).

The diagnosis system operates in normal mode

during normal vehicle use. In normal mode, 2-trip

detection logic is used to ensure accurate detection

of malfunctions. Check mode is also available to

technicians as an option. In check mode, 1-trip

detection logic is used for simulating malfunction

symptoms and increasing the system’s ability to

detect malfunctions, including intermittent

malfunctions.

(f)

2-trip detection logic: When a malfunction is first

detected, the malfunction is temporarily stored in

the ECM memory (1st trip). If the ignition switch is

turned off and then turned to the ON position again,

and same malfunction is detected again, the MIL

illuminates.
