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.

DIAGNOSTIC TROUBLE CODE PROCEDURES
DTC P0830: Clutch Switch (5M/T Only)
.
CIRCUIT OPERATION
A 5 Volt power supply is applied to the clutch
switch output terminal (terminal No. 1) from the
ENGINE-ECU(terminal No. B-21 pin 41) when
the clutch pedal is applied the power supply is
switched to earth.
.
TECHNICAL DESCRIPTION
The ENGINE-ECU uses the clutch switch earth-
ing as a signal that clutch pedal has been
applied.
.
DTC SET CONDITIONS
Check Conditions
Vehicle speed is above 50 km/h.Judgement Criteria
Gear shift is above 5 times.
Clutch control is below 2 times.
No MIL.
No Limp home.
.
TROUBLESHOOTING HINTS (The most
likely causes for this code to be set are:)
Clutch switch failed
Harness damage in clutch switch circuit, or con-
nector damage.
Refer to component locations GROUP-70
Refer to configuration diagrams GROUP-80

STEP 1. Using diagnostic tool , check data list item 78:
Clutch Switch.
To prevent damage to diagnostic tool , always turn the
ignition switch to the "LOCK"(OFF) position before con-
necting or disconnecting diagnostic tool .
(1) Connect diagnostic tool to the data link connector.
(2) Turn the ignition switch to the "ON" position.
(3) Set diagnostic tool to the data reading mode for item 78,
Clutch Switch.
When the clutch pedal is depressed the display on diag-
nostic tool should read "ON".
When the clutch pedal is released the display on diag-
nostic tool should read "OFF".
(4) Turn the ignition switch to the "LOCK"(OFF) position.
Q: Is the switch operating properly?
YES : It can be assumed that this malfunction is intermittent.
Refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points
How to
Cope with Intermittent Malfunctions 00-14.
NO : Then go to Step 2.
STEP 2. Check the clutch pedal adjustment and switch
operation.
Refer to GROUP 21A, Clutch - On-vehicle Service - Clutch
Pedal Check and Adjustment P.21A-2
Q: Is the pedal and switch adjustment correct?
YES : Go to Step 3.
NO : Adjust the pedal or replace the switch if damaged or
not operating correctly. Then go to Step 6.

AUTO-CRUISE CONTROL
ENGINE AND EMISSION CONTROL17-17
STEP 3. Measure the clutch switch power supply voltage
by backprobing the clutch switch connector C-07 (terminal
1).
(1) Measure the voltage between terminal No. 1 and ground.
Voltage should be battery positive voltage.
Q: Is battery positive voltage (approximately 12 volts)
present?
YES : Go to Step 5.
NO : Then go to Step 4.
STEP 4. Check harness connector C-07 at Clutch switch
for damage, loose or corroded terminals .
Q: Is the harness connector in good condition?
YES : Then go to Step 5.
NO : Repair or replace it. Refer to GROUP 00E, Harness
Connector Inspection 00E-2. Then go to Step 6.

ENGINE AND EMISSION CONTROL17-18
STEP 4. Measure the power supply voltage at ENGINE-ECU
connector B-21 by using ENGINE-ECU check harness
special tool MB992044.
(1) Disconnect the all ENGINE-ECU connectors and connect
ENGINE-ECU check harness special tool MB992044
between the separated connectors.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal No. 41 and ground.
Voltage should be battery positive voltage.
(4) Turn the ignition switch to the "LOCK" (OFF) position.
Q: Is battery positive voltage (approximately 12 volts)
present?
YES : Repair or replace the open or damaged wiring circuit
between ENGINE-ECU connector B-21 and Clutch
switch connector C-07. Then go to Step 8.
NO : Check the connector B-21 for damage and ensure
check harness connection t ENGINE-ECU is correct.
If connection is correct and no power supply is
present at terminal 41 of ENGIN-ECU then replace it.
Then go to Step 7.
STEP 5. Measure the clutch switch power supply voltage
by backprobing the clutch switch connector C-07 (terminal
2).
(1) Measure the voltage between terminal No. 2 and ground by
backprobing. while depressing the clutch pedal.
When pedal is not depressed an (open circuit) , voltage
should be battery positive voltage.
When pedal is depressed an (closed circuit) , voltage
should be less than 1.0 volt.
Q: Is there battery voltage at terminal No. 2 when pedal is
depressed?
YES : Go to Step 6.
NO : Replace the Clutch switch. Refer to GROUP 21A,
