DTC P1700 [AW6A-EL, AW6AX-EL]

id050211805000

DTC P1700

Valve control solenoid circuit malfunction at R range (valve stuck)

DETECTION CONDITION

•   When all of the following conditions are met while driving in R position and the counter drive gear (output} speed is 500 rpm or less:

―  The difference between the engine and turbine shaft speeds is less than 150 rpm

―   The turbine shaft speed is more than the estimated turbine speed value, as derived from the counter drive gear (output) speed, plus 200 rpm.

Diagnostic support note:

•  The MIL illuminates if the TCM detects the above malfunction condition during the first drive cycle.

•  A PENDING CODE is not available.

•  FREEZE FRAME DATA is available.

•  The AT warning light illuminates.

•  The DTC is stored in the TCM memory.

POSSIBLE CAUSE

•  Line pressure malfunction

―  Oil pump malfunction

―  Control valve stuck

•  Stall speed malfunction

―  C3 clutch slipping

―  B2 brake slipping

•  Solenoid valve malfunction

―  Line pressure control solenoid stuck

―  Shift solenoid A stuck

―  Shift solenoid B stuck

―  Shift solenoid E stuck

•  TCM malfunction

DTC P1700	Valve control solenoid circuit malfunction at R range (valve stuck)
DETECTION CONDITION	• When all of the following conditions are met while driving in R position and the counter drive gear (output} speed is 500 rpm or less: ― The difference between the engine and turbine shaft speeds is less than 150 rpm ― The turbine shaft speed is more than the estimated turbine speed value, as derived from the counter drive gear (output) speed, plus 200 rpm. Diagnostic support note: • The MIL illuminates if the TCM detects the above malfunction condition during the first drive cycle. • A PENDING CODE is not available. • FREEZE FRAME DATA is available. • The AT warning light illuminates. • The DTC is stored in the TCM memory.
POSSIBLE CAUSE	• Line pressure malfunction ― Oil pump malfunction ― Control valve stuck • Stall speed malfunction ― C3 clutch slipping ― B2 brake slipping • Solenoid valve malfunction ― Line pressure control solenoid stuck ― Shift solenoid A stuck ― Shift solenoid B stuck ― Shift solenoid E stuck • TCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded on the repair order?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related repair information availability. • Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. • If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT LINE PRESSURE • Perform the “Line Pressures Test”. (See MECHANICAL SYSTEM TEST [AW6A-EL, AW6AX-EL].) • Is there any malfunction?	Yes	All ranges: Replace the oil pump, then go to Step 6. Any ranges: Replace the control valve body, then go to Step 6. (See CONTROL VALVE BODY REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)
3		No	Go to the next step.
4	INSPECT STALL SPEED • Perform the “Stall Test”. (See MECHANICAL SYSTEM TEST [AW6A-EL, AW6AX-EL].) • Is there any malfunction?	Yes	Replace the automatic transaxle, then go to Step 6. (See AUTOMATIC TRANSAXLE REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)
4		No	Go to the next step.
5	INSPECT SOLENOID VALVE • Inspect the following solenoid valves: (See SOLENOID VALVE INSPECTION [AW6A-EL, AW6AX-EL].) ― Line pressure control solenoid ― Shift solenoid A ― Shift solenoid B ― Shift solenoid E • Is there any malfunction?	Yes	Replace malfunctioning part according to test result, then go to the next step.
5		No	Go to the next step.
6	VERIFY TROUBLESHOOTING OF DTC P1700 COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC from the memory using the M-MDS. • Drive the vehicle in R position. • Is same DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)
6		No	Go to the next step.
7	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE [AW6A-EL, AW6AX-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [AW6A-EL, AW6AX-EL].)
7		No	DTC troubleshooting completed.
