DESCRIPTION
While the engine is being cranked, battery voltage is applied to terminal STA of the TCM.
If the TCM detects the Starter Control (STA) signal while the vehicle is being driven, it determines that there is a malfunction in the STA circuit. The TCM then illuminates the MIL and sets the DTC.
This monitor runs when the vehicle is driven at 20 km/h (12.43 mph) for over 20 seconds.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| P0617 | When conditions (a), (b) and (c) are met, positive (+B) battery voltage 10.5 V or more applied to TCM for 20 seconds (1 trip detection logic): (a) Vehicle speed more than 20 km/h (12.43 mph) (b) Engine speed more than 1000 rpm (c) STA signal ON |

Tech Tips
The following troubleshooting flowchart is based on the premise that the engine is cranked normally. If the engine does not crank, proceed to the problem symptoms table Click here.
PROCEDURE
READ VALUE USING GTS (STARTER SIGNAL)
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Enter the following menus: Powertrain / ECT / Data List.
| Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
|---|---|---|---|
| Starter Signal | Starter signal/ ON or OFF |
ON: Starter operating OFF: Starter not operating |
- |
Crank the engine.
Read the value displayed on the GTS.

CHECK HARNESS AND CONNECTOR (TCM - PARK/NEUTRAL POSITION SWITCH ASSEMBLY)
| *a | Front view of wire harness connector (to TCM) |
Disconnect the D6 TCM connector.
Remove the ST relay from the engine room relay block and junction block assembly.
Disconnect the D5 park/neutral position switch assembly connector.
Measure the voltage according to the value(s) in the table below.

CHECK WHETHER DTC OUTPUT RECURS
Connect the GTS to the DLC3.
Turn the engine switch on (IG).
Turn the GTS on.
Clear the DTCs Click here.
Drive the vehicle in accordance with the driving pattern described in the Confirmation Driving Pattern.
Enter the following menus: Powertrain / ECT/ Trouble Codes.
