NG >> Repair open circuit or short to ground or short to power
in harness or connectors.
3.CHECK DTC
Perform Diagnostic Trouble Code (DTC) confirmation procedure. Refer to AT- 1 7 1 , "
DIAGNOSTIC TROUBLE
CODE (DTC) CONFIRMATION PROCEDURE" .
OK or NG

DescriptionECS004S2
Shift solenoid valves A and B are turned “ON” or “OFF” by the TCM
in response to signals sent from the PNP switch, vehicle speed and
throttle position sensors. Gears will then be shifted to the optimum
position.

DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DURE” has been previously conducted, always turn ignition
switch “OFF” and wait at least 5 seconds before conducting the
next test.
After the repair, perform the following procedure to confirm the mal-
function is eliminated.
With CONSULT-II
1. Turn ignition switch “ON” and select “DATA MONITOR” mode for
“ENGINE” with CONSULT-II.
2. Start engine.
3. Drive vehicle in D position and allow the transmission to shift 1
→ 2 → 3 (“GEAR”).
With GST
Follow the procedure “With CONSULT-II”.
