5. SPARK PLUGS (REPLACE)M1001002000346
Iridium plugs are used. Use care not to damage the iridium
tips of the plugs. Do not adjust the spark plug gap.
1. Spark plugs must spark properly to assure proper engine
performance and reduce exhaust emission level. Therefore,
they should be replaced periodically with new ones( Refer to
Maintainence Schedule).
Spark plug type
2. The new plugs should be checked for the proper gap.
Spark plug gap: 1.0
1.1 mm
3. Install the spark plugs and tighten to 25
5 Nm (18 4
ft-lb).
6. TIMING BELT (REPLACE)M1001002300273
Replace the belt with a new one according to the vehicle main-
tenance schedule to assure proper engine performance.

NOTE: If it takes some amount of time until the transmission
fluid reaches its normal operating temperature [70
80C
(158
176F)], check the transmission fluid level by refer-
ring to the left diagram.
2. Park the vehicle on a level surface.
3. Move the selector lever through all positions to fill the torque
converter and the hydraulic circuits with fluid, and then move
the selector lever to the "N" position.
4. After wiping off any dirt around the dipstick, remove the
dipstick and check the condition of the transmission fluid.
NOTE: If the transmission fluid smells as if it is burnt, it
means that the transmission fluid has been contaminated by
fine particles from the bushings and friction materials. Tran-
saxle overhaul and cooler line flushing may be necessary.
5. Check transmission fluid level is at the "HOT" mark on the
dipstick. If the transmission fluid level is less than this, add
DIAMOND ATF SP III until the level reaches the "HOT"
mark.
NOTE: If the transmission fluid level is too low, the oil pump
will draw in air along with the transmission fluid, which will
cause to form bubbles. If the transmission fluid level is too
high, rotating components inside the transaxle will churn the
fluid and air into a foamy liquid. Both conditions (level too
low or too high) will cause the hydraulic pressure to drop,
which will result in late shifting and slipping of the clutches
and brakes.
NOTE: In either case, air bubbles can interfere with normal
valve, clutch, and brake operation. Also, foaming can cause
transmission fluid to escape from the transaxle vent where it
may be mistaken for a leak.

A/T DIAGNOSTIC TROUBLESHOOTING STRATEGYM1231007600339
Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will find most A/T mal-
functions.
1. Gather as much information as possible about the
complaint from the customer.
2. Verify that the condition described by the
customer exists.
3. Check the vehicle for any A/T Diagnostic Trouble
Codes (DTCs).
4. If you can not verify the condition and there are no
DTCs, the malfunction is intermittent. For
information on how to cope with intermittent
malfunctions, refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
How
to Cope with Intermittent Malfunction P.00-14.
5. If you can verify the condition but there are no
DTCs, or the system can not communicate with
diagnostic tool, refer to the Symptom Chart
P.23A-35.6. If there is a DTC, record the number of the code,
then erase the code from memory using
diagnostic tool.
7. Reconfirm the symptom with a Road Test.
8. If a DTC is set again, go to the Inspection Chart
for Diagnostic Trouble Codes.
9. If a DTC is not set again, the malfunction is
intermittent. For information on how to cope with
intermittent malfunctions, refer to GROUP 00,
How to Use Troubleshooting/Inspection Service
Points
How to Cope with Intermittent
Malfunction P.00-14.
10.After repairs are completed, conduct a Road Test
duplicating the complaint conditions to confirm the
malfunction has been eliminated.
DIAGNOSTIC FUNCTIONM1231022500135
CHECK "N" RANGE LIGHT
The "N" range light flashes once per second if there is an
abnormality in any of the items in the table below which are
related to the A/T system. Check for diagnostic trouble codes if
the "N" range light is flashing once per second.
NOTE: The "N" indicator lamp warning function does not
operate with the selector lever in the "P" (PARK), "R"
(REVERSE) or "N" (NEUTRAL) position.
"N" range light flashing items
Input shaft speed sensor
Output shaft speed sensor
Each solenoid valve
Gear incorrect ratio
A/T control relay system
If the "N" range light is flashing rapidly (twice per second),
the transmission fluid temperature is too high. (It flashes
when the fluid is approximately 125
C or more and goes
off when the fluid is approximately 115
C or less)
ON-BOARD DIAGNOSTICS
The automatic transmission -electronic control unit
(A/T-ECU) monitors its input/output signals (some
signals all the time and others under specified condi-
tions). When an irregular signal is initially monitored,
the A/T-ECU decides that a malfunction has
occurred and records the occurrence as a diagnostic
trouble code. The diagnostic results can be read with diagnostic tool. Diagnostic trouble codes are kept in
memory by direct battery feed. The codes are
retained in memory even if the ignition switch is in
the "LOCK" (OFF) position. DTCs are not erased
even after the battery terminals and the A/T-ECU
connector are disconnected. In addition, the diagnos-
tic trouble code can also be erased by diagnostic
tool.

TORQUE CONVERTER STALL TESTM1231005400362
This test measures the maximum engine speed when the
selector lever is in the "D" or "R" position and the torque con-
verter stalls. This tests the operation of the torque converter,
starter motor and one-way clutch operation, as well as the hold-
ing performance of the clutches and brakes in the transmission.
Do not let anyone stand in front of or behind the vehi-
cle while this test is performed.
1. Check the transmission fluid level and temperature. Check
the engine coolant temperature.
Transmission fluid level: At the "HOT" mark on the dipstick
Transmission fluid temperature: 70 80C
Engine coolant temperature: 80 100C
NOTE: Measures transmission fluid temperature with
diagnostic tool MB991958 (MUT-III sub assembly).
2. Check both rear wheels.
3. Pull the parking brake lever on, with the brake pedal fully
depressed.
4. Start the engine. 9 Transmission
