DTC P0617
DTC P0617: Starter Cut Relay Diagnosis Circuit High Voltage
General Description
The starter control system prevents sudden vehicle move when it is in the driving range by prohibiting starter activation while the shift lever position is in other than P or N. It also prevents damaging the starter pinion gear by prohibiting starter activation while the engine is running. If the powertrain control module (PCM) judges that the shift lever position is in other than P or N when the vehicle is turned to the START mode, the PCM prohibits the starter activation. If the vehicle is turned mistakenly while the engine is running, the PCM judges to prohibit the starter activation according to the engine speed information and stops applying power to the starter cut relays. In this system, two starter cut relays are connected in series (starter cut relay 1, starter cut relay 2) to prevent the starter from continuing to run due to a starter cut relay malfunction. Also a diagnosis line (STRLD) is connected to monitor the voltage between the starter cut relay 1 and starter cut relay 2. Based on the diagnosis line signals, the PCM detects an OPEN malfunction of diagnosis line, an ON malfunction of starter cut relay 1, and an ON malfunction of starter cut relay 2. If the voltage of the diagnosis line (STRLD) is a specified voltage for a set time when the starter switch (STS) is OFF, the PCM detects an ON malfunction of starter cut relay 1 and stores a DTC.

Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory. The MIL does not come on.
Conditions for clearing the DTC
The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
