|
In the case of the vehicle equipped
with immobilizer, perform "KEY TEACHING" procedure together
(Refer to "IMMOBILIZER" in BE
group). |
•
|
When replacing an PCM, the VIN must be
programmed in the PCM. If there is no VIN in PCM memory, the
fault code (DTC P0630) is
set. | |
1. |
Turn ignition switch OFF and disconnect the
negative (-) battery cable. |
2. |
Remove the cover of the PCM & relay box
(A).

|
3. |
Disconnect the PCM connectors
(A).

|
4. |
Unscrew the PCM bracket mounting bolt (B)
and the nuts (C), and then remove the
PCM. |
5. |
Install a new PCM.
PCM
installation bolts (on bracket) :
9.8 ~ 11.8 N·m (1.0 ~ 1.2 kgf·m, 7.2 ~
8.7 lbf·ft)
PCM bracket
installation bolt/nuts:
9.8 ~ 11.8 N·m (1.0 ~ 1.2 kgf·m, 7.2 ~
8.7 lbf·ft)
| |
6. |
Perform "Key Teaching" procedure (Refer to
"IMMOBILIZER" in BE group). |
7. |
Input the Vehicle Identification Number
(VIN) (Refer to "VIN PROGRAMMING PROCEDURE" in this
group). |
PCM Problem Inspection
Procedure |
1. |
TEST PCM GROUND CIRCUIT: Measure resistance
between PCM and chassis ground using the backside of PCM harness
connector as PCM side check point. If the problem is found, repair
it.
Specification
(Resistance): 1Ω or
less
| |
2. |
TEST PCM CONNECTOR: Disconnect the PCM
connector and visually check the ground terminals on PCM 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
PCM could be faulty. If so, replace the PCM with a new one, and then
check the vehicle again. If the vehicle operates normally then the
problem was likely with the PCM. |
4. |
RE-TEST THE ORIGINAL PCM : Install the
original PCM (may be broken) into a known-good vehicle and check the
vehicle. If the problem occurs again, replace the original PCM with
a new one. If problem does not occur, this is intermittent problem
(Refer to INTERMITTENT PROBLEM PROCEDURE in BASIC INSPECTION
PROCEDURE). |
VIN
Programming Procedure
VIN (Vehicle
Identification Number) is a number that has the vehicle's information
(Maker, Vehicle Type, Vehicle Line/Series, Body Type, Engine Type,
Transmission Type, Model Year, Plant Location and so forth. For more
information, please refer to the group "GI" in this SERVICE MANUAL). When
replacing an PCM, the VIN must be programmed in the PCM. If there is no
VIN in PCM memory, the fault code (DTC P0630) is set.
The programmed VIN cannot be changed. When
writing the VIN, confirm the VIN
carefully. |
1. |
Select "Vehicle" and "Engine" (For example,
TUCSON 2.0L L4).

|
2. |
Select "VIN WRITING".

|
3. |
Check the PCM status.

• |
VIRGIN: VIN is not
programmed |
• |
LEARNT: VIN has been already
programmed | |
Is the PCM status "VIRGIN"?

▶ Go to next step 4.

▶ END |
4. |
Write the VIN with cursor, function and
number keys.
Before pressing the "ENTER" key,
confirm the VIN again because the programmed VIN cannot be
changed. |

|
5. |
After verifying the written VIN, press the
"ENTER" key. |
6. |
Turn the ignition switch OFF, and then turn
ON.

|
7. |
Verify the programmed VIN in the PCM
memory. |
