Diagnostic procedure
STEP
1
VERIFY RELATED REPAIR INFORMATION
AVAILABILITY
• Check for related Service Bulletins availability.
• Is any related repair information available?
2
CHECK ATF CONDITION
• Check ATF condition.
(See
K12 AUTOMATIC TRANSAXLE FLUID
(ATF)
INSPECTION.)
• Is it okay?
3
CHECK ATF LEVEL
• Start engine.
• Warm up ATX.
• Is ATF level within specification?
(See
K12 AUTOMATIC TRANSAXLE FLUID
(ATF)
INSPECTION.)
4
INSPECTION SHIFT SOLENOID VALVE A, B
AND C FOR CLICK SOUND
• Perform inspection of operation. (See
SOLENOID VALVE
• Verify the click sound of shift solenoid A, B,
and C when applying B+ to each transale
connector terminal.
• Was click heard from solenoids?
5
INSPECT LINE PRESSURE
• Start engine.
• Measure line pressures.
Specification
Idle: 330470 kPa {3.44.7 kgf/cm
psi}
Stall: 1,1601,320 kPa {11.913.4 kgf/cm
170190 psi}
• Is line pressure within specification?
(See
K6 Line Pressure
6
INSPECT STALL SPEED
• Measure stall speed in D range.
(See
K7 Stall
Specification
2,0002,600 rpm
• Is stall speed within specification?
7
INSPECT FREQUENCY OF INPUT/TURBINE
SPEED SENSOR WHEN DRIVING VEHICLE
• Turn ignition key to OFF.
• Connect WDS or equivalent.
• Start engine.
• Measure frequency of input/turbine speed
sensor while driving vehicle under the following
conditions:
Vehicle speed: 40 km/h {24 mph} (VSS
PID)
Drive in D range, 2nd gear
Throttle opening angle: about 25% (TP PID)
• Was frequency of input/turbine speed sensor at
appro. 1,156 Hz?
