In the case of the vehicle equipped with
immobilizer or button engine start system, perform "Key Teaching"
procedure together (Refer to "Immobilizer" or "Button Engine Start
System in BE group). |

TCM Problem Inspection
Procedure |
1. |
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.
|
2. |
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. |
3. |
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. |
4. |
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).

When shift shock is
occurred or parts related with the transaxle are replaced, TCM learning
should be performed.
In the following case,
TCM learning is required.
• |
Transaxle assembly
replacement |
1. |
TCM learning condition
- ATF temperature: 60~115°C
(140~239°F) |
2. |
TCM learning procedure
A. |
Stop learning
Repeat the below shift pattern four
times or more with stepping on the brake.

|
1. |
Drive the vehicle through all gears at D
range. Drive from stop to 1st to 2nd to 3rd to 4th to 5th to
6th with keeping fixed throttle
open. |
2. |
Down shift from 6th to 5th, 5th to 4th,
4th to 3rd, 3rd to 2nd, 2nd to
1st. |
3. |
Repeat the above driving pattern four
times or
more. | |
Up-shift throttle open :
15~30% |
