10. MANUAL SHIFTING TEST
HINT:
With this test, it can be determined whether the trouble is within
the electrical circuit or is a mechanical problem in the transaxle.
(a) Disconnect the solenoid wire.
(b) Inspect the manual driving operation
Check that the shift and gear positions correspond with
the table below.
Shift PositionGear Position
DO/D
23rd
L1st
RReverse
PPawl Lock
HINT:
If the L, 2 and D position gear position are difficult to distinguish,
do the following road test.
While driving, shift through the L, 2 and D positions.
Check that the gear change corresponds to the shift posi-
tion.
If any abnormality is found in the above test, the problem
is in the transaxle itself.
(c) Connect the solenoid wire.
(d) Cancel out the DTC (See step 3).

PROBLEM SYMPTOMS TABLE
If a normal code is displayed during the diagnostic trouble code check but the trouble still occurs, check the
circuits for each symptom in the order given in the charts on the following pages and proceed to the page
given for troubleshooting.
The Matrix Chart is divided into 3 chapters.
Chapter 1: Electronic Circuit Matrix Chart
Chapter 2: On−Vehicle repair Matrix Chart
Chapter 3: Off−Vehicle repair Matrix Chart
When troubleshooting, check Chapter 1 first. If instructions are given in Chapter 1 to proceed to chapter 2
or 3, proceed as instructed.
(1) If the instruction ”Proceed to next circuit inspection shown on matrix chart” is given in the flow
chart for each circuit, proceed to the circuit with the next highest number in the table to continue
the check.
(2) If the trouble still occurs even though there are no abnormalities in any of the other circuits, then
check and replace the ECM.
