starts only when the shift lever is in the N or P
position and the engine does not start when the shift
lever is in other positions.
(c) Check that the back up light comes on and the
reverse warning buzzer sounds only when the shift
lever is in the R position and the light and buzzer do
not operate when the shift lever is in other positions.
(d) If a failure is found, check the park/neutral position
switch for continuity.
2. INSPECT PARK/NEUTRAL POSITION SWITCH
ASSEMBLY
(a) Jack up the vehicle.
(b) Disconnect the park/neutral position switch
connector.
(c) Measure the resistance according to the value(s) in
the table below when the shift lever is moved to
each position.
Resistance
ADJUSTMENT
1. ADJUST PARK/NEUTRAL POSITION SWITCH
ASSEMBLY
(a) Loosen the 2 bolts of the park/neutral position
switch and move the shift lever to the N position.
(b) Align the groove with the neutral basic line.
(c) Hold the switch in position and tighten the 2 bolts.
Torque: 5.4 N*m (55 kgf*cm, 48 in.*lbf)
(d) After adjustment, perform the inspection described
in park/neutral position switch assembly operation.

MANUAL SHIFTING TEST
1. PERFORM MANUAL SHIFTING TEST
HINT:
• With this test, it can be determined whether the
trouble occurs in the electrical circuit or is a
mechanical problem in the transaxle.
• If any abnormalities are found in the following test, the
problem is in the transaxle itself.
(a) Disconnect the connector of the transmission wire.
(b) Drive with the transmission wire disconnected.
Shifting the shift lever in the order of L, 2, 3, 4 and D
position to check whether the shifting condition
changes the table below.
HINT:
When driving with the transmission wire
disconnected, the shift lever position is in L or 2, the
gear position is held in 3rd and the shift lever
position is in 3, 4 or D, the gear position is held in
4th. However, when the shift position is in R or P, the
operation is same as usual.
(c) Connect the connector of the transmission wire.
(d) Clear the DTC (See page AX-27).

INITIALIZATION
1. RESET MEMORY
NOTICE:
• Perform the RESET MEMORY (AT initialization)
when replacing the automatic transaxle assembly,
engine assembly or ECM.
• The RESET MEMORY can be performed only with
the Intelligent tester.
HINT:
The ECM memorizes the condition that the ECT controls
the automatic transaxle assembly and engine assembly
according to those characteristics. Therefore, when the
automatic transaxle assembly, engine assembly, or ECM
has been replaced, it is necessary to reset the memory
so that the ECM can memorize the new information.
Reset procedure is as follows.
(a) Turn the engine switch off.
(b) Connect the intelligent tester together with the CAN
VIM (controller area network vehicle interface
module) to the DLC3.
(c) Turn the ignition switch to the ON position and push
the intelligent tester main switch on.
(d) Select the item "DIAGNOSIS / ENHANCED OBD
II".
(e) Perform the reset memory procedure from the
ENGINE menu.
CAUTION:
After performing the RESET MEMORY, be sure
to perform the ROAD TEST (See page AX-9)
described earlier.
HINT:
The ECM is learned by performing the ROAD TEST.
