--- | ---
DETECTION CONDITION | • Conditions: TCM communication normal • Circumstances: Short circuit between shift solenoid B and GND systems detected • Time period: Determined after 5 times lasting 0.1 or more seconds Diagnostic support note: • The MIL illuminates if the TCM detects the above malfunction condition during the first drive cycle. • The AT warning light illuminates. • PENDING CODE is not available. • FREEZE FRAME DATA is available. • The DTC is stored in the TCM memory.
FAIL-SAFE FUNCTION | • Inhibits learning control • Inhibits 1GR (M position)
POSSIBLE CAUSE | • Coupler component connector or terminal malfunction • Short to GND in wiring harness between shift solenoid B terminal B and TCM terminal B2 • Shift solenoid B connector or terminal malfunction • Solenoid valve malfunction ― Shift solenoid B • 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.
No | Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2 | VERIFY RELATED REPAIR INFORMATION AVAILABILITY • Verify related Service 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.
No | Go to the next step.
3 | INSPECT COUPLER COMPONENT CONNECTOR FOR POOR CONNECTION • Switch the ignition OFF. • Remove the TCM. (See TCM REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].) • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 7.
No | Go to the next step.
4 | INSPECT SHIFT SOLENOID B CIRCUIT FOR SHORT TO GND • Switch the ignition OFF. • Inspect for continuity between coupler component terminal B2 (wiring harness-side) and body GND. • Is there continuity? | Yes | Repair or replace the wiring harness for a possible short to GND, then go to Step 7.
No | Go to the next step.
5 | INSPECT SHIFT SOLENOID B CONNECTOR FOR POOR CONNECTION • Switch the ignition OFF. • Disconnect the shift solenoid B connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction? | Yes | Repair or replace the terminal, then go to Step 7.
No | Go to the next step.
6 | INSPECT SHIFT SOLENOID B • Inspect the shift solenoid B. (See SHIFT SOLENOID B INSPECTION [AY6A-EL, AY6AX-EL].) • Is there any malfunction? | Yes | Replace the shift solenoid B, then go to the next step. (See SHIFT SOLENOID B REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)
No | Go to the next step.
7 | VERIFY DTC TROUBLESHOOTING COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC using the M-MDS. • Perform the following procedure to ensure that the DTC has been resolved: 1. Start the engine. 2. Warm up the engine and transaxle. 3. Drive the vehicle in D position and make sure that the gears shift smoothly from 1GR to 6GR. • Is the same DTC present? | Yes | Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)
No | Go to the next step.
8 | VERIFY NO DTCs ARE PRESENT • Perform the “Reading DTCs Procedure”. (See ON-BOARD DIAGNOSTIC SYSTEM DTC INSPECTION [AY6A-EL, AY6AX-EL].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See ON-BOARD DIAGNOSTIC SYSTEM DTC TABLE [AY6A-EL, AY6AX-EL].)
No | DTC troubleshooting completed.
