5.
Remove the TCM (B) after removing the mounting bolt (C) and nuts (D).
TCM installation bolt/nut :
(B) 7.8 ~ 9.8 N.m (0.8 ~ 1.0 kgf.m, 5.8 ~ 7.2 lb-ft)
TEST TCM GROUND CIRCUIT: Measure resistance between TCM and chassis ground using the backside of TCM harness connector as TCM side check point. If the problem is found, repair it.
Specification: Below 1Ω
TEST TCM CONNECTOR: Disconnect the TCM connector and visually check the ground terminals on TCM side and harness side for bent pins or poor contact pressure. If the problem is found, repair it.
If problem is not found in Step 1 and 2, the TCM could be faulty. If so, make sure there were no DTC's before swapping the TCM with a new one, and then check the vehicle again. If DTC's were found, examine this first before swapping TCM.
RE-TEST THE ORIGINAL TCM: Install the original TCM (may be broken) into a known-good vehicle and check the vehicle. If the problem occurs again, replace the original TCM with a new one. If problem does not occur, this is intermittent problem (Refer to “Intermittent Problem Inspection Procedure” in Basic Inspection Procedure).
Turn ignition switch OFF.
Disconnect the negative (-) battery cable.
Remove the head lamp (L/H).
(Refer to "Lighting system" in BE group.)
Disconnect the TCM connector (A).
Remove the TCM (B) after removing the mounting bolt (C) and nuts (D).
TCM installation bolt/nut :
(B) 7.8 ~ 9.8 N.m (0.8 ~ 1.0 kgf.m, 5.8 ~ 7.2 lb-ft)
Installation is reverse of removal.
Perform Transaxle Control Module(TCM) learning after replacing the valve body to prevent slow transaxle response, jerky acceleration and jerky startup. (Refer to Automatic Transaxle Control System - "Repair procedures")
Perform "Injector Specific Data Input" procedure (Refer to Engine Control System - "Injector").
After replacing the ECM of the vehicle with the immobilizer, the following procedure must be performed.
[If installing a used ECM]
1) Perform "ECM Neutral Mode" procedure using GDS. (Refer to "Body Electrical System - "Immobilizer System - Repair procedures")
2) After finishing "ECM Neutral Mode", perform "Key Teaching" procedure using GDS. (Refer to "Body Electrical System - "Immobilizer System - Repair procedures")
[If installing a new ECM]
Perform "Key Teaching" procedure using GDS. (Refer to "Body Electrical System - "Immobilizer System - Repair procedures")
After replacing the ECM of the vehicle with the smart key system (button start), the following procedure must be performed.
[If installing a used ECM]
1) Perform "ECM Neutral Mode" procedure using GDS. (Refer to "Body Electrical System - "Smart key System - Repair procedures")
2) After finishing "ECM Neutral Mode", turn IGN ON then OFF using the smart key or start button. Then the ECM learns information on the smart key automatically.
[If installing a new ECM]
Turn IGN ON then OFF using the smart key or start button. Then the ECM learns information on the smart key automatically.
