NO.8 DOES NOT SHIFT TO 5GR [FS5A-EL]

id050308809300

8 | Does not shift to 5GR
--- | ---
DESCRIPTION | • Vehicle does not upshift from 4GR to 5GR even though vehicle speed is increased. • Vehicle does not shift to 5GR even though accelerator pedal is released in D range at 60 km/h {37 mph}.
POSSIBLE CAUSE | • Basically, TCC does not operate when the fail-safe is operating. Verify the DTCs first. If the TCC operates when driving at high speeds only, the malfunction (improper adjustment) is in the TR switch circuit. Caution • If the TCC is stuck, inspect it. In addition, inspect the oil cooler for foreign particles which may have mixed in with the ATF. 1. TCC piston slippage, burned • Line pressure low • TP sensor malfunction • APP sensor malfunction • Engine coolant temperature sensor malfunction • Vehicle speed sensor malfunction • Input/turbine speed sensor malfunction • Sensor GND malfunction 2. Transaxle fluid temperature sensor malfunction • Short or open circuit in wiring harness • Poor connection of connector • Sensor malfunction 3. TR switch malfunction • Short or open circuit in wiring harness • Poor connection of connector • Sensor malfunction • Selector lever adjustment incorrect • TR switch adjustment incorrect 4. Shift solenoid A, shift solenoid B, shift solenoid D, Shift solenoid F valve malfunction • Short or open circuit in wiring harness • Poor connection of connector • Solenoid valve stuck 5. M range switch malfunction 6. Control valve body malfunction Note • Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted.

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | With the ignition switch at the ON position, does the gear position indicator light indication correspond to the selector lever position? | Yes | Go to the next step.
No | Go to No.27 "GEAR POSITION INDICATOR LIGHT DOES NOT ILLUMINATE IN M RANGE" or No. 28 "GEAR POSITION INDICATOR LIGHT ILLUMINATES IN D RANGE OR P, N, R POSITIONS"
2 | Inspect the value at the following TCM PIDs using the WDS or equivalent. (See TCM INSPECTION [FS5A-EL].) • TFT • TFTV Are the PID values normal? | Yes | Go to the next step.
No | Repair or replace any malfunctioning parts.
3 | Inspect the value at the following TCM PIDs using the WDS or equivalent. (See TCM INSPECTION [FS5A-EL].) • SSA/SS1 • SSB/SS2 • SSD/SS4 • SSF_SS6 Are the PID values normal? | Yes | Overhaul the control valve body and repair or replace any malfunctioning parts. (See ATX workshop manual [FS5A-EL].) If any problem remains, overhaul the transaxle and repair or replace any malfunctioning parts. (See ATX workshop manual [FS5A-EL].)
No | Go to the next step.
4 | Disconnect the TCM connector. Is the resistance between the ground terminal at the TCM connector and the body ground less than 5.0 ohms? | Yes | Inspect the value at the following TCM PIDs using the WDS or equivalent. (See TCM INSPECTION [FS5A-EL].) • TR • TSS • OSS Repair or replace any malfunctioning parts.
No | Repair open ground circuit. Reconnect the TCM.
5 | • Verify the test results. - If normal, return to the diagnostic index to service any additional symptoms. - If the malfunction remains, inspect the related Service information and perform repair or diagnosis. • If the vehicle is repaired, troubleshooting is completed. • If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM.
