DTC P1730:
14-19514-195
16. Reconnect all connectors.
17. Update the PCM if it does not have the latest
software (see page 11-227), or substitute a known-
good PCM (see page 11-7).
18. Start the engine with the shift lever in P. Shift to N, then shift to R while pressing the brake pedal, and
wait for at least 2 seconds.
19. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals between the transmission range switch
and the PCM. If the PCM was updated, substitute a
known-good PCM (see page 11-7), then go to step
18. If the PCM was substituted, go to step 1.
Go to step 20.
20. Monitor the OBD STATUS for P1717 in the DTCs MENU with the HDS.
If the PCM was updated, troubleshooting is
complete. If the PCM was substituted, replace the
original PCM (see page 11-228). If any other
Temporary DTCs or DTCs were indicated in step 19,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor
connections or loose terminals between the
transmission range switch and the PCM. If the PCM
was updated, substitute a known-good PCM
(see page 11-7), then go to step 18. If the PCM was
substituted, go to step 1. If the HDS indicates NOT
COMPLETED, go to step 18.  Shift Solenoid Valves A or D Stuck OFF
 Shift Solenoid Valve B Stuck ON
 Shift Valves A, B, or D Stuck
NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot with the HDS, and review
the General Troubleshooting Information (see page
14-3).
1. Warm up the engine to normal operating temperature (the radiator fan comes on).
2. Make sure that the transmission is filled to the proper level, and check for fluid leaks.
3. Drain the ATF (see step 3 on page 14-232) through a strainer. Inspect the strainer for metal debris or
excessive clutch material.
Replace the transmission, then go to step 14.
Replace the ATF (see page 14-232), then go to
step 4.
4. Turn the ignition switch to ON (II).
5. Clear the DTC with the HDS.
6. Test-drive the vehicle with the shift lever in D, and let the transmission shift through all five gears.
7. Monitor the OBD STATUS for P1730 in the DTCs MENU with the HDS.
Go to step 8.
If the HDS indicates PASSED, intermittent
failure, the system is OK at this time. If the HDS
indicates NOT COMPLETED, go to step 6.
8. Clear the DTC with the HDS.

1. Make sure the transmission fluid is filled to the
proper level (see page 14-231).
2. Apply the parking brake, and block all four wheels.
3. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
4. Turn the ignition switch to ON (II), and go to the A/T Data List. Make sure the HDS communicates with
the PCM. If it does not, go to the DLC circuit
troubleshooting (see page 11- 204).
5. Make sure the A/C switch is OFF.
6. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
7. Shift to D while pressing the brake pedal firmly, then fully press the accelerator pedal for
6 to 8 seconds, and note the engine speed. Do not
move the shift lever or remove your foot off the
brake pedal while raising the engine speed.
8. Allow 2 minutes for cooling, then repeat the test in SandR.
NOTE: Do not test the stall speed for more than 10 seconds at a time.
 The stall speed tests should be used for diagnostic purposes only.
 Stall speed test results should be the same with the shift lever in D, S, and R.
 Do not test the stall speed with the A/T oil pressure gauges installed. 9. If the stall speeds are out of the service limit, the
problems and probable causes are listed in the
table.

 VSA DTC(s) may come on during the pressure test. If the VSA(s) come on, clear the DTC(s) with the HDS.
1. Make sure the transmission fluid is filled to the proper level (see page 14-231).
2. Raise the vehicle on a lift, or apply the parking brake, block rear wheels, and raise the front of the
vehicle. Make sure it is securely supported.
3. Remove the splash shield.
4. Allow the front wheels to rotate freely.
5. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
6. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go
to the DLC circuit troubleshooting (see page
11-204). 7. Connect the A/T oil pressure gauge to the line
pressure inspection port (A). Do not allow dust or
other foreign particles to enter the ports while
connecting the gauges.
8. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
9. Measure the line pressure at the line pressure inspection port with the shift lever in P or N while
holding the engine speed at 2,000 rpm.
NOTE: Higher pressure may be indicated if
measurements are made in shift lever position
other than P or N.

10. Turn the engine off, then disconnect the A/T oil pressure gauge from the line pressure inspection
port.
11. Install the sealing bolt to the line pressure inspection port with a new sealing washer, and
tighten the bolt to 18 N·m (1.8 kgf·m, 13 lbf·ft). Do
not reuse the old sealing washer.
