SNAPSHOT DISPLAY WITH TIS2000



Procedures for transferring and displaying Tech2
snapshot data by using TIS2000 [Snapshot Upload]
function is described below.
Snapshot data can be displayed with [Snapshot
Upload] function included in TIS2000.
By analyzing these data in various methods, trouble
conditions can be checked.

DTC P0602 (FLASHING CODE 63) Transmission Control Module (TCM)
Programming Error
Circuit Description
The Service Programming System (SPS) updates the
flash calibration files that are stored in a Transmission
Control Module (TCM). The calibration file
custom-tailors a module to a certain vehicle. The
calibration file contains data for things such as spark
curves and fuel control. When troubleshooting a
driveability problem, diagnosis may call fo
r
reprogramming the controller with newer calibration
information to correct a customer concern and Vehicle
Identification Number (VIN).
Condition for setting the DTC
When the TCM is not written VIN No.
Action Taken When The DTC Sets

DTC stored.
Conditions For Clearing The DTC

The DTC can be cleared from the TCM history by
using a scan tool.
 The DTC will be cleared from history when the
vehicle has achieved 40 warm-up cycles without a
failure reported.

After more than 1 second has elapsed after the
ignition key has been turned “ON", short between
No.11 and No.4 (ground) of DLC (Data Link
Connector). Then, after 1 second, but within 6
seconds, discontinue shorting.
Diagnostic Aids
DTC P0602 is indicated when the TCM does not written
VIN No. A security lock is performed by SPS. And not
replace the TCM when DTC P0602 can repair by SPS.
