DTC P0826

Steering shift switch circuit malfunction (open circuit/short to ground)

DETECTION CONDITION

•  TCM detects open or short circuit in steering shift switch circuit when engine is running.

Diagnostic support note:

•  MIL illuminates if TCM detects the above malfunction condition during the first drive cycle.

•  PENDING CODE is not available.

•  FREEZE FRAME DATA is available.

•  AT warning light illuminate.

•  DTC is stored in the TCM memory.

POSSIBLE CAUSE

•  Audio control switch connector or terminal malfunction

•  Short to ground in wiring harness between audio control switch terminal F and TCM terminal 2AF

•  Steering shift switch malfunction

•  TCM connector or terminal malfunction

•  Short to power in wiring harness between audio control switch terminal F and TCM terminal 2AF

•  Open circuit in wiring harness between audio control switch terminal F and TCM terminal 2AF

•  Open circuit in wiring harness between audio control switch terminal C and TCM terminal 2AB

•  TCM malfunction

DTC P0826	Steering shift switch circuit malfunction (open circuit/short to ground)
DETECTION CONDITION	• TCM detects open or short circuit in steering shift switch circuit when engine is running. Diagnostic support note: • MIL illuminates if TCM detects the above malfunction condition during the first drive cycle. • PENDING CODE is not available. • FREEZE FRAME DATA is available. • AT warning light illuminate. • DTC is stored in the TCM memory.
POSSIBLE CAUSE	• Audio control switch connector or terminal malfunction • Short to ground in wiring harness between audio control switch terminal F and TCM terminal 2AF • Steering shift switch malfunction • TCM connector or terminal malfunction • Short to power in wiring harness between audio control switch terminal F and TCM terminal 2AF • Open circuit in wiring harness between audio control switch terminal F and TCM terminal 2AF • Open circuit in wiring harness between audio control switch terminal C and TCM terminal 2AB • 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.
1		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.
2		No	Go to the next step.
3	INSPECT AUDIO CONTROL SWITCH CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Disconnect the audio control switch connector. • Inspect for poor connection at audio control switch terminals F and C (such as damaged/pulled-out pins, corrosion). • Are the connector and terminals normal?	Yes	Go to the next step.
3		No	Repair or replace the connector and/or terminal, then go to Step 10.
4	INSPECT SHIFT CONTROL SIGNAL CIRCUIT FOR SHORT TO GROUND • Inspect for continuity between the audio control switch (wiring harness-side) terminal F and body ground. • Is there continuity?	Yes	Repair or replace the wiring harness, then go to Step 10.
4		No	Go to the next step.
5	INSPECT STEERING SHIFT SWITCH • Inspect the steering shift switch. (See STEERING SHIFT SWITCH INSPECTION.) • Is the steering shift switch normal?	Yes	Go to the next step.
5		No	Replace the steering shift switch, then go to Step 10. (See AUDIO CONTROL SWITCH REMOVAL/INSTALLATION.)
6	INSPECT TCM CONNECTOR FOR POOR CONNECTION • Disconnect the TCM connector. • Inspect for poor connection at TCM terminals 2AB and 2AF (such as damaged/pulled-out pins, corrosion). • Are the connector and terminals normal?	Yes	Go to the next step.
6		No	Repair or replace the connector and/or terminal, then go to Step 10.
7	INSPECT SHIFT CONTROL SIGNAL CIRCUIT FOR SHORT TO POWER SUPPLY • Turn the ignition switch to the ON position (engine off). • Measure the voltage at TCM (wiring harness-side) terminal 2AF. • Is the voltage 5.0 V or more?	Yes	Repair or replace the wiring harness for short to power supply, then go to Step 10.
7		No	Go to the next step.
8	INSPECT SHIFT CONTROL SIGNAL CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between the audio control switch (wiring harness-side) terminal F and TCM (wiring harness-side) terminal 2AF. • Is there continuity?	Yes	Go to the next step.
8		No	Repair or replace the wiring harness, then go to Step 10.
9	INSPECT SHIFT CONTROL SIGNAL GROUND CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between the audio control switch (wiring harness-side) terminal C and TCM (wiring harness-side) terminal 2AB. • Is there continuity?	Yes	Go to the next step.
9		No	Repair or replace the wiring harness, then go to Step 10.
10	VERIFY TROUBLESHOOTING OF DTC P0826 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the TCM memory using the M-MDS. • Drive the vehicle in M range, and change gears by operating the steering shift switch. • Is the same DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
10		No	Go to the next step.
11	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE [SJ6A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SJ6A-EL].)
11		No	DTC troubleshooting completed.
