DTC P0817

Starter lock output signal circuit malfunction (open circuit/short circuit)
DETECTION CONDITION
•  Any of the following conditions are met when ignition switch is at ON position:
―  0 V detected at TCM terminal A5 when in D range or R position
―  12 V detected at TCM terminal A5 when in P or N position
Diagnostic support note:
•  The MIL does not illuminate if the TCM detects the above malfunction condition during the first drive cycle.
•  A PENDING CODE is not available.
•  FREEZE FRAME DATA is available.
•  The AT warning light illuminates.
•  The DTC is stored in the TCM memory.
POSSIBLE CAUSE
•  Open circuit between PCM terminal 1F and TCM terminal A5
•  Short to ground in wiring harness between PCM terminal 1F and TCM terminal A5
•  Short to power in wiring harness between PCM terminal 1F and TCM terminal A5
•  PCM malfunction
•  Damaged connector between PCM and TCM
•  TCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
•  Has the FREEZE FRAME DATA been recorded?
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 VOLTAGE OF STARTER LOCK OUTPUT SIGNAL CIRCUIT
•  Turn the ignition switch to the ON position (engine off).
•  Shift the selector lever to P or N position.
•  Inspect for voltage TCM connector terminal A5 (wiring harness-side).
•  Is the voltage 0 V?
Yes
Go to go to Step 5.
No
Go to the next step.
4
INSPECT TCM CONNECTOR FOR POOR CONNECTION
•  Disconnect the TCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Are terminals normal?
Yes
Go to Step 10.
No
Replace the couple component, then go to Step 10.
5
INSPECT VOLTAGE OF STARTER LOCK OUTPUT SIGNAL CIRCUIT
•  Shift the selector lever to D range or R position.
•  Inspect for voltage TCM connector terminal A5 (wiring harness-side).
•  Is the voltage B+?
Yes
Go to go to Step 10.
No
Go to the next step.
6
INSPECT PCM FOR POOR CONNECTION
•  Turn the ignition switch to the LOCK position.
•  Disconnect the PCM connector.
•  Inspect for poor connection (such as damaged/pulled-out pins, corrosion).
•  Are terminals normal?
Yes
Go to the next step.
No
Replace the couple component, then go to Step 10.
7
INSPECT STARTER LOCK OUTPUT SIGNAL CIRCUIT FOR OPEN CIRCUIT
•  Inspect for continuity between TCM connector terminal A5 and PCM terminal 1F (wiring harness-side).
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the harness, then go to Step 10.
8
INSPECT STARTER LOCK OUTPUT SIGNAL CIRCUIT FOR SHORT TO GROUND
•  Inspect for continuity between PCM terminal 1F (wiring harness-side) and body ground.
•  Is there continuity?
Yes
Repair or replace the harness, then go to Step 10.
No
Go to the next step.
9
INSPECT STARTER LOCK OUTPUT SIGNAL CIRCUIT FOR SHORT TO POWER
•  Turn the ignition switch to the ON position (engine off).
•  Inspect the voltage at PCM terminal 1F (wiring harness-side).
•  Is the voltage 0 V?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to the next step.
10
VERIFY TROUBLESHOOTING OF DTC P0817 COMPLETED
•  Make sure to reconnect all the disconnected connectors.
•  Clear the DTC from the memory using the M-MDS.
•  Drive the vehicle in D range.
•  Is the same DTC present?
Yes
Replace the TCM, then go to the next step.
(See TCM REMOVAL/INSTALLATION [AW6AX-EL].)
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “After Repair Procedure”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [AW6AX-EL].)
No
DTC troubleshooting completed.
