P0600 A/T CONTROL

System Description
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).

ECM Terminals And Reference Value:

On Board Diagnosis Logic
Malfunction is detected when ECM receives incorrect voltage from TCM (Transmission Control Module) continuously.

POSSIBLE CAUSE
- Harness or connectors
[The circuit between ECM and TCM (Transmission Control Module) is open or shorted.]

DTC Confirmation Procedure

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.
