CONTROL UNIT (RAM), CONTROL UNIT (ROM)
DescriptionINFOID:0000000001713102
The TCM consists of a microcomputer and connectors for signal
input and output and for power supply. The unit controls the A/T.
On Board Diagnosis LogicINFOID:0000000001713103
Diagnostic trouble code “CONTROL UNIT (RAM)”, “CONTROL UNIT (ROM)” with CONSULT-III is detected
when TCM memory (RAM) or (ROM) is malfunctioning.
Possible CauseINFOID:0000000001713104
TCM.
DTC Confirmation ProcedureINFOID:0000000001713105
CAUTION:
If performing this “DTC Confirmation Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.

1. Turn ignition switch ON and select “DATA MONITOR” mode for TRANSMISSION with CONSULT-III.
2. Touch “START”.
3. Start engine.
4. Run engine for at least 2 seconds at idle speed.
5. If the check result is NG, go to TM-413, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000001713106
1.CHECK DTC
With CONSULT-III
1. Turn ignition switch ON and select “SELF-DIAG RESULTS” mode for TRANSMISSION with CONSULT-III.
2. Touch “ERASE”.

Reference ValueINFOID:0000000001714339
REFERENCE VALUES
NOTICE:
1. The CONSULT-III electrically displays shift timing and lock-up timing (that is, operation timing of each
solenoid).
Check for time difference between actual shift timing and the CONSULT-III 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-III 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-III indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-III at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).

TCM
If non-standard solenoid signal is sent to TCM, torque converter clutch solenoid valve is turned OFF to release
lock-up.
Overrun Clutch Solenoid Valve
If non-standard solenoid signal is sent to TCM, overrun clutch solenoid valve is turned OFF to engage overrun
clutch. This will result in more effective engine brake during deceleration.
