General Description

Shift control solenoid valve is supply oil pressure usually,TCM output "ON" signal to solenoid valve then oil pressure not supplied to Clutch "B". Solenod4(Clutch E & Brake D), Solenod5(Line pressure) are same type solenoid valve.

If electrical power source not spplied to all of solenoid valve, the oil pressure supplied to 3 solenoid valves and shift gear is fixed at 3rd gear as mechanical operation.

DTC Description

TCM set this code If detected short to ground / open for solenoid valve cirduit.(MIL ON : 2 driving Cycle)

DTC Detecting Condition

Item	Detecting Condition	Possible Cause
DTC Strategy	● Short to ground / open	● Mechatronics(E-module + Valvebody)
Enable Conditions	● Voltage drop at the voltage regulator ≤ 1V ● Supply voltage ≥ 8.7V
Threshold Value	● Short to ground / open
Diagnostic Time	● 0.05second
Fail Safe	● High speed : fixed at 5th gear, low speed : fixed at 3rd gear. ● Reverse : Shift lock(Push "Unlock button → possible to shift) (priority : 3)

caution

The function with the higher priority will aiways take precedence. However, a low-priority is not overruled by a higher priority function.

Functions from different priority categories can also run in parallel. It is important to note which function will take precedence in this case.

In such an event it is possible for a substitute function with low priority not be carried out if a second, higher-priority function is present. This has been taken into account when compiling the priority list and is international.

The mechanical emergency run function must always have the highest priority, since from the electrical standpoint it is the only safe condition.

Monitor Scantool Data

Connect scan tool to data link connector(DLC), Ignition "ON"

Erase DTC and Engine "ON"

Monitor the "Shift control solenoid valve(SOL 2)" parameter on the scan tool.

Select "D" range and Drive vehicle, confirm output data of solenoid valves.

Dose "Shift control solenoid valve(SOL 2)" operated normally ?

	▶ Fault is intermittent caused by poor contact in the sensor's and/or PCM/TCM's connector or was repaired and PCM/TCM memory was not cleared. Throughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage.Repair or replace as necessary and go to "verification of vehicle repair" procedure
	▶ Go to "Component Inspection" procedure

Component Inspection

Ignition "ON" & Engine "OFF".

Connect scantool and check DTC.

Erase the DTC with scantool.

After turning IG OFF to IG ON twice or three times, check DTC again.

Does the scantool show same DTC again ?

	▶ Substitute with a known-good Mechatronics (Valve-body + TCM) and check for proper operation. If the problem is corrected,replace Mechatronics (Valve-body + TCM) and then go to "Verification of Vehicle Repair" procedure.

How to perform Initial Learning

If you replace the automatic transmission or Mechatronics (Valve-body + TCM), or if you overwrite the TCU software, be sure to initialize the learned values and perform initial learning.

Step 1) Warm-up

Raise the ATF temperature by leaving the vehicle idling or performing city drive. Check the ATF temperature using the Scan-tool and make sure it is between 50°C( 122 °F) and 120°C( 248 °F). If the ATF temperature is outside this range, work to bring the range.

caution

Don't raise the oil temperature by stalling the engine.

(Reference)

If the oil temperature is not between 50°C( 122 °F) and 120°C ( 248 °F), initial learning can not be performed. Before learning, check for variable speed shock or shift shock.

STEP 2) Driving learning

Select "D" range then depress accelerator pedal smoothly, and keep the APS value 17%, shift gear to 5th gear.

RKeep the vehicle speed over 60kM/h.

In condition that release the accelerator pedal and then depress the brake pedal narmally.Stop the vehicle then keep 5seconds.

STEP 3) Repeat this procedure 10 times.(Not necessary N-D,N-R Learning)

Verification of Vehicle Repair

After a repair, it is essential to verify that the fault has been corrected.

Connect scantool and select "Diagnostic Trouble Codes(DTCs)" mode.

Using a scan tool, Clear DTC.

Operate the vehicle within DTC Enable conditions in General information.

Are any DTCs present ?

	▶ Go to the applicable troubleshooting procedure.
	▶ System performing to specification at this time.
