Diagnostic Procedure
EBS009K1
1. CHECK OVERALL FUNCTION
With CONSULT-II
1. Turn ignition switch "ON".
2. Select "BRAKE SW" in "DATA MONITOR" mode with CON-
SULT-II.
3. Check "BRAKE SW" signal under the following conditions.
OK or NG
OK >>INSPECTION END
NG >> GO TO 2.
2. CHECK STOP LAMP SWITCH POWER SUPPLY CIRCUIT
1. Turn ignition switch "OFF".
2. Disconnect stop lamp switch harness connector.
3. Check voltage between stop lamp switch terminal 1 and ground
with CONSULT-II or tester.
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3. DETECT MALFUNCTION PART
Check the following
●15A fuse
●Fuse block (J/B) connector M2
●Harness for open and short between stop lamp switch and battery
>> Repair open circuit or short to ground or short to power in harness or connectors.
Conditions BRAKE SW
Brake pedal released OFF
Brake pedal slightly depressed ON

CLUTCH PEDAL
FREE PLAT INSPECTION
●Press the clutch pedal by hand until certain resistance can be
felt. Using a scale, check that the free play is within the specified
range.
CLEARANCE CHECK
1. Start the engine and let it idle.
2. Apply parking brake.
3. Depress the brake pedal.
4. Fully depress clutch pedal and shift to 1st gear.
5. Release clutch pedal gradually. Stop releasing the pedal at the
point where the clutch is about to be engaged. Using a scale,
check the clearance between the clutch pedal and floor panel to
see if it is within the specified range.
NOTE:
Pedal height at clutch disengagement varies slightly from the clutch engagement point. Despite this, pedal
height at clutch engagement is commonly used for both cases in order to simplify the inspection.

FLUID LEAKAGE CHECK
1. Clean area suspected of leaking. — for example, mating surface
of converter housing and transmission case.
2. Start engine, apply foot brake, place selector lever in “D” posi-
tion and wait a few minutes.
3. Stop engine.
4. Check for fresh leakage.

TROUBLE DIAGNOSIS — BASIC INSPECTION
5. CHECK LOCK-UP (D4 TO D4 L/U)
Does A/T perform lock-up at the specified speed?
Read vehicle speed, throttle position when lock-up duty becomes 94%.
Ye s o r N o
Yes >> GO TO 6
No >> Mark the box of “A/T Does Not Perform Lock-up” on the
DIAGNOSTIC WORKSHEET. Continue Road Test.
6. CHECK HOLD LOCK-UP
Does A/T hold lock-up condition for more than 30 seconds?
Ye s o r N o
Yes >> GO TO 7
No >> Mark the box of “A/T Does Not Hold Lock-up Condition” on the DIAGNOSTIC WORKSHEET.
Continue Road Test.
7. CHECK SHIFT DOWN (D4 L/U TO D4 )
1. Release accelerator pedal.
2. Is lock-up released when accelerator pedal is released?
Ye s o r N o
Yes >> GO TO 8
No >> Mark the box of “Lock-up Is Not Released” on the DIAG-
NOSTIC WORKSHEET. Continue Road Test.
8. CHECK SHIFT DOWN (D4 TO D3 )
1. Decelerate vehicle by applying foot brake lightly.
2. Does engine speed return to idle smoothly when A/T is shifted from D
4 to D3 ?
Read gear position and engine speed.
Ye s o r N o
Yes >> 1. Stop vehicle.
2. Go To “Cruise test — Part 2”, AT- 8 1
.
No >> Mark the box of “Engine Speed Does Not Return To Idle
(Light Braking D
4→ D3 )” on the DIAGNOSTIC WORK-
SHEET. Continue Road Test. Specified speed when lock-up occurs:
