DTC P0817:00 | Starter lock output signal circuit
--- | ---
DETECTION CONDITION | • B+ short ― Conditions: Ignition switch ON, TCM communication normal, in D or R position ― Circumstances: 0V detected for start lock output voltage ― Time period: Determined after 2 times lasting 0.1 or more seconds • GND short / open ― Conditions: Ignition switch ON, TCM communication normal, in P or N position ― Circumstances: 12V detected for start lock output voltage ― Time period: Determined after 2 times lasting 0.1 or more seconds Diagnostic support note: • The MIL does not illuminate. • 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 | —
POSSIBLE CAUSE | • Open circuit between PCM terminal 1Q and TCM terminal A5 • Short to ground in wiring harness between PCM terminal 1Q and TCM terminal A5 • Short to power in wiring harness between PCM terminal 1Q 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 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 VOLTAGE OF STARTER LOCK OUTPUT SIGNAL CIRCUIT • Switch the ignition ON (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 position 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 • Switch the ignition OFF. • 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 1Q (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 1Q (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 • Switch the ignition ON (Engine off). • Inspect the voltage at PCM terminal 1Q (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 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 to normal operating temperature. 3. Drive the vehicle in D position. • 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.
11 | 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.
