DTC P0600 A/T COMMUNICATION LINE
PFP:23710
System Description
UBS00DMQ
These circuit lines are used to control the smooth shifting up and down of A/T during the hard acceleration/
deceleration.
Voltage signals are exchanged between ECM and TCM (Transmission Control Module).
On Board Diagnosis Logic
UBS00DMR
The MIL will not light up for this diagnosis.
*: This DTC can be detected only by “DATA MONITOR (AUTO TRIG)” with CONSULT-II.
DTC Confirmation Procedure
UBS00DMS
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 5 seconds before conducting the next test.
WITH CONSULT-II
1.
Turn ignition switch ON.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Start engine, and rev engine more than 1,000 rpm once, then let
it idle for more than 40 seconds.
4.
If DTC 1st trip is detected, go to
WITH GST
Follow the procedure “WITH CONSULT-II”.
DTC No.

Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than the ECM terminals, such as the ground.
