P0600

COMPONENT 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
Specification data are reference values, and are measured between each terminal and (25) (ECCS ground).






ON BOARD DIAGNOSIS LOGIC
* Freeze frame data is not stored in the ECM for the "A/T control". The MIL will not light for "A/T control" malfunction.

DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE

CAUTION: Always drive vehicle at a safe speed.

NOTE:
- If "DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCEDURE" has been previously conducted, always turn ignition switch "OFF" and wait at least 5 seconds before conducting the next test.
- If any diagnostic trouble code is displayed performing self-diagnosis for A/T, perform the trouble diagnosis for the DTC first.

(1) Jack up drive wheels.
(2) Make sure that selector lever is set in "P" or "N" position.
(3) Turn ignition switch "ON".


With Generic Scan Tools
(4) Start engine and raise engine speed to more than 1,000 rpm at once.
(5) Run engine at least 10 seconds at idle speed.
(6) Run engine at least 10 seconds at 2,000 rpm.
(7) Set selector lever in "D" position and run engine at least 10 seconds at idle speed (with vehicle stopped).
(8) Drive vehicle at 12 to 20 km/h (7 to 12 MPH) for at least 10 seconds in "D" position.
(9) Select "Mode 3" with GST.
