id050208802700

DTC P0819 | Manual switch/up switch/down switch circuit malfunction (open circuit/short circuit)
--- | ---
DETECTION CONDITION | M range switch circuit malfunction • M range switch remains on for 2 s or more except in D range. Up switch or down switch circuit malfunction • When all of the following conditions are met: ― M range switch off. ― Except D range ― Up or down switch remains on for 10 s or more. Diagnostic support note: • The MIL does not illuminate. • The AT warning light illuminates if the TCM detects the above malfunction condition during the first drive cycle. • PENDING CODE is not available. • FREEZE FRAME DATA is available. • The DTC is stored in the TCM memory.
POSSIBLE CAUSE | • TCM connector or terminal malfunction • Selector lever component connector or terminal malfunction • Short to GND in wiring harness between selector lever component terminal B and TCM terminal 2G • Short to GND in wiring harness between selector lever component terminal D and TCM terminal 2J • Short to GND in wiring harness between selector lever component terminal F and TCM terminal 2F • M range switch malfunction • Up switch malfunction • Down switch malfunction. • Open circuit in wiring harness between selector lever component terminal A and body GND • Open circuit in wiring harness between selector lever component terminal B and TCM terminal 2G • Open circuit in wiring harness between selector lever component terminal D and TCM terminal 2J • Open circuit in wiring harness between selector lever component terminal F and TCM terminal 2F • 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 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.
No | Go to the next step.
3 | INSPECT TCM CONNECTOR FOR POOR CONNECTION • Disconnect the TCM connector. • Inspect for poor connection at TCM terminals 2F, 2G and 2J (such as damaged/pulled-out pins, corrosion). • Are terminals normal? | Yes | Go to the next step.
No | Repair or replace the connector and/or terminal, then go to Step 9.
4 | INSPECT SELECTOR LEVER COMPONENT CONNECTOR FOR POOR CONNECTION • Disconnect the selector lever component connector. • Inspect for poor connection at selector lever component terminals A, B, D and F (such as damaged/pulled-out pins, corrosion). • Are terminals normal? | Yes | Go to the next step.
No | Repair or replace the connector and/or terminal, then go to Step 9.
5 | INSPECT M RANGE SWITCH, UP SWITCH, AND DOWN SWITCH CIRCUIT FOR SHORT TO GND • Inspect for continuity between selector lever component terminals (wiring harness-side) and body GND. ― Terminal B and body GND (M range switch) ― Terminal D and body GND (up switch) ― Terminal F and body GND (down switch) • Is there continuity? | Yes | Repair or replace the harness, then go to Step 9.
No | Go to the next step.
6 | INSPECT M RANGE SWITCH, UP SWITCH, AND DOWN SWITCH • Inspect the M range switch, up switch, and down switch. (See SELECTOR LEVER INSPECTION) • Are the switches normal? | Yes | Go to the next step.
No | Replace the selector lever, then go to Step 9. (See SELECTOR LEVER REMOVAL/INSTALLATION.)
7 | INSPECT M RANGE SWITCH, UP SWITCH, AND DOWN SWITCH CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between selector lever component terminal A (wiring harness-side) and body GND. • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the harness, then go to Step 9.
8 | INSPECT M RANGE SWITCH, UP SWITCH, AND DOWN SWITCH CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between TCM terminals (wiring harness-side) and selector lever component terminals (wiring harness-side). ― Terminal 2G and terminal B (M range switch) ― Terminal 2J and terminal D (up switch) ― Terminal 2F and terminal F (down switch) • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the harness, then go to the next step.
9 | VERIFY TROUBLESHOOTING OF DTC P0819 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 to normal operating temperature. 3. Drive the vehicle in M range, and shift the selector lever (operate up and down switches) between 1GR to 6GR for 10 s or more. • Is the same DTC present? | Yes | Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
No | Go to the next step.
10 | VERIFY NO DTC HAS BEEN PRESENTED • Perform the “Reading DTCs Procedure”. (See AUTOMATIC TRANSMISSION ON-BOARD DIAGNOSTIC FUNCTION [SJ6A-EL].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [SJ6A-EL].)
No | DTC troubleshooting completed.
