PrecautionsBCS000ZG

Before connecting or disconnecting the TCM harness con-
nector, turn ignition switch OFF and disconnect negative
battery terminal. Failure to do so may damage the TCM.
Because battery voltage is applied to TCM even if ignition
switch is turned off.

When connecting or disconnecting pin connectors into or
from TCM, take care not to damage pin terminals (bend or
break).
Make sure that there are not any bends or breaks on TCM
pin terminal, when connecting pin connectors.

Before replacing TCM, perform TCM input/output signal
inspection and make sure whether TCM functions properly
or not. (See page AT- 6 4 , "
TCM Terminals and Reference
Val ue".)

After performing each TROUBLE DIAGNOSIS, perform
“DTC (Diagnostic Trouble Code) Confirmation Procedure”.
The DTC should not be displayed in the “DTC Confirmation
Procedure” if the repair is completed.

Before proceeding with disassembly, thoroughly clean the out-
side of the transaxle. It is important to prevent the internal parts
from becoming contaminated by dirt or other foreign matter.

Disassembly should be done in a clean work area.

Use lint-free cloth or towels for wiping parts clean. Common shop rags can leave fibers that could interfere
with the operation of the transaxle.

Place disassembled parts in order for easier and proper assembly.

All parts should be carefully cleaned with a general purpose, non-flammable solvent before inspection or
reassembly.

Gaskets, seals and O-rings should be replaced any time the transaxle is disassembled.

It is very important to perform functional tests whenever they are indicated.

The valve body contains precision parts and requires extreme care when parts are removed and serviced.
Place disassembled valve body parts in order for easier and proper assembly. Care will also prevent
springs and small parts from becoming scattered or lost.

Properly installed valves, sleeves, plugs, etc. will slide along bores in valve body under their own weight.

Before assembly, apply a coat of recommended ATF to all parts. Apply petroleum jelly to protect O-rings
and seals, or hold bearings and washers in place during assembly. Do not use grease.

Extreme care should be taken to avoid damage to O-rings, seals and gaskets when assembling.

After overhaul, refill the transaxle with new ATF.

When the A/T drain plug is removed, only some of the ATF is drained. Old ATF will remain in torque con-
verter and ATF cooling system.
Always follow the procedures under “Changing A/T Fluid” in the AT section when changing A/T fluid. Refer
to “Changing A/T Fluid”, AT- 1 4 , "
Checking A/T Fluid" .

PRECAUTIONS

Service Notice or PrecautionsBCS000ZH
TORQUE CONVERTER SERVICE
The torque converter should be replaced under any of the following conditions:

External leaks in the hub weld area.

Converter hub is scored or damaged.

Converter pilot is broken, damaged or fits poorly into crankshaft.

Steel particles are found after flushing the cooler and cooler lines.

Pump is damaged or steel particles are found in the converter.

Vehicle has TCC shudder and/or no TCC apply. Replace only after all hydraulic and electrical diagnoses
have been made. (Converter clutch material may be glazed.)

Converter is contaminated with engine coolant containing antifreeze.

Internal malfunction of stator roller clutch.

Heavy clutch debris due to overheating (blue converter).

Steel particles or clutch lining material found in fluid filter or on magnet when no internal parts in unit are
worn or damaged — indicates that lining material came from converter.
The torque converter should not be replaced if:

The fluid has an odor, is discolored, and there is no evidence of metal or clutch facing particles.

The threads in one or more of the converter bolt holes are damaged.

Transaxle malfunction did not display evidence of damaged or worn internal parts, steel particles or clutch
plate lining material in unit and inside the fluid filter.

Vehicle has been exposed to high mileage (only). The exception may be where the torque converter
clutch dampener plate lining has seen excess wear by vehicles operated in heavy and/or constant traffic,
such as taxi, delivery or police use.

TROUBLE DIAGNOSIS

TROUBLE DIAGNOSISPFP:00004
DTC Inspection Priority ChartBCS000ZX
If some DTCs are displayed at the same time, perform inspections one by one based on the following priority
chart.
NOTE:
If DTC “CAN COMM CIRCUIT” is displayed with other DTCs, first perform the trouble diagnosis for
“CAN COMMUNICATION LINE”. Refer to AT- 1 3 3
.
Fail-safeBCS000ZY
The TCM has an electronic Fail-safe mode. This allows the vehicle to be driven even if a major electrical input/
output device circuit is damaged.
Under Fail-safe, the vehicle always runs in third gear, even with a shift lever position of “1”, “2”, “3” or “D”. The
customer may complain of sluggish or poor acceleration.
Always follow the AT- 3 7 , "
WORK FLOW" .
The SELF-DIAGNOSIS results will be as follows:

The first SELF-DIAGNOSIS will indicate damage to the vehicle speed sensor or the revolution sensor.

During the next SELF-DIAGNOSIS, performed after checking the sensor, no damages will be indicated.
FAIL-SAFE FUNCTION
The following fail-safe functions allow vehicles to be driven even when sensor, switch or solenoid malfunction
occurs.
Vehicle Speed Sensor 1 (Revolution Sensor)
Vehicle speed sensor 2 signal is input from combination meter.
Accelerator Pedal Position Sensor Signal
TCM controls the throttle opening angle to a predetermined fixed position to enable driving if a malfunctioning
signal is input to TCM.
Park/Neutral Position (PNP) Switch
When the multiple PNP switch signals are input to TCM, the priority of selector lever position becomes “D”·“3”,
“N”, “R”, “2” and “1” in order by internal TCM determination.
The use of 4th gear is inhibited until normal operation resumes. Because the hydraulic circuit of the control
valve is switched by manual valve according to the selector lever position, however, actual operating condition
of vehicle becomes as follows.

CONSULT-II Function (A/T) BCS0010D
CONSULT-II can display each diagnostic item using the diagnostic test models shown following.
FUNCTION
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
–Actual shift schedule has more or less tolerance or allowance,
–Shift schedule indicated in Service Manual refers to the point where shifts start, and
–Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).
