DESCRIPTION

There are many operating conditions that may cause a malfunction
of the transmission parts. By understanding those conditions prop-

ADDITIONAL SERVICE WHEN REPLACING TCM

Description

INFOID:0000000009650110

When replacing the TCM, perform the following work.

LOADING AND STORING OF CALIBRATION DATA

• The TCM acquires calibration data (individual characteristic value) of each solenoid that is stored in the

ROM assembly (in the control valve). This enables the TCM to perform accurate control. After the TCM is
replaced, check that the calibration data is correctly loaded and stored.

CAUTION:

When replacing TCM and transaxle assembly as a set, replace transaxle assembly first and then
replace TCM.
If the TCM is replaced in advance, perform “ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE
ASSEMBLY”. Refer to

TM-62, "Description"

Procedure

INFOID:0000000009650111

CAUTION:

Immediately after TCM is replaced or after control valve or transaxle assembly is replaced (after TCM
initialization is complete), self-diagnosis result of “P1701”, “P1709” may be displayed. In this case,
erase self-diagnosis result using CONSULT. After erasing self-diagnosis result, perform DTC P1701,
P1709 reproduction procedure and check that malfunction is not detected. Refer to

TM-114, "DTC

Logic"

(P1701),

TM-118, "DTC Logic"

(P1709).

LOAD CALIBRATION DATA

Shift the selector lever to the “P” position.

Turn ignition switch ON.

Check that “P” is displayed on shift position indicator on combination meter.
NOTE:
Displayed approximately 1 – 2 seconds after the selector lever is moved to the “P” position.

Does the shift position indicator display “P”?

YES

>> GO TO 3.

>> GO TO 2.

DETECT MALFUNCTIONING ITEM

Check the following items:
• Harness between the TCM and the ROM assembly inside the transaxle assembly is open or shorted.
• Disconnected, loose, bent, collapsed, or otherwise abnormal connector housing terminals
Is the inspection result normal?

YES

>> GO TO 1.

>> Repair or replace the malfunctioning parts.

STORE CALIBRATION DATA

Turn ignition switch OFF and wait for 5 seconds.

Turn ignition switch ON.

Does the shift position indicator display “P” at the same time when turning ON the ignition switch?

YES

>> WORK END

>> Check harness between battery and TCM harness connector terminal. Refer to

TM-114, "Diagno-
