TM-126 < BASIC INSPECTION > [CVT: RE0F11A] ADDITIONAL SERVICE WHEN REPLACING TCM ADDITIONAL SERVICE WHEN REPLACING TCM Description INFOID:0000000009019886 When replacing the TCM, perform the following work. CHECK LOADING 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 TCM has correctly loaded the calibration data. CALIBRATION OF G SENSOR • TCM stores calibration data (inherent characteristic value) of G sensor to provide accurate control. There- fore, it is required to perform calibration of G sensor after the replacement of TCM. 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” after “G sensor calibration”. Procedure INFOID:0000000009019887 1. CHECK WORK CONTENTS Replacing only the TCM>>GO TO 2. Replacing the TCM after the transaxle assembly is replaced>>GO TO 2. Replacing the transaxle assembly after the TCM is replaced>>GO TO 5. 2. LOADING OF CALIBRATION DATA 1. Shift the selector lever to the “P” position. 2. Turn ignition switch ON. 3. Check that “P” is displayed on shift position indicator on combination meter. NOTE: Displayed approximately 4 – 5 seconds after the selector lever is moved to the “P” position. Does the shift position indicator display “P”? YES >> GO TO 3. NO >> GO TO 4. 3. PERFORM G SENSOR CALIBRATION >> WORK END 4. 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 YES >> GO TO 2. NO >> Repair or replace the malfunctioning parts. 5. PERFORM G SENSOR CALIBRATION >> Perform “ADDITIONAL SERVICE WHEN REPLACING TRANSAXLE ASSEMBLY” after “CALI- BRATION OF G SENSOR”. Refer to |
