DTC P0617 Starter Relay Circuit High


DESCRIPTION

While the engine is being cranked, positive (+) battery voltage is applied to terminal STA of the ECM.
If the ECM detects the Starter Control (STA) signal while the vehicle is being driven, it will conclude that there is fault in the starter control circuit. The ECM will turn on the Malfunction Indicator Lamp (MIL) and set a DTC.
This monitor runs when the vehicle is driven at 20 km/h (12 mph) for over 20 seconds.

DTC No.

INSPECTION PROCEDURE

HINT:
Read freeze frame data using the intelligent tester. Freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch ON and turn the tester ON.

  1. Enter the following menus: Powertrain / Engine and ECT / Data List / Starter SIG.

  1. Confirm the starter signal status when the ignition switch is operated.
