DTC P0617:  Starter Cut Relay 1 Control Circuit High Voltage

General Description 

GHH646325Courtesy of HONDA, U.S.A., INC.

The ST_RLY_1_TO_2 line monitors the voltage of the line between the starter cut relay 1 circuit and the starter cut relay 2 circuit. The voltage level when the starter cut relay 1 circuit and the starter cut relay 2 circuit are on/on or off/off are measured to detect stuck on and stuck off of each relay and open circuit of the ST_RLY_1_TO_2 line. If the ST_RLY_1_TO_2 voltage is a specified value while the starter is off, the PCM detects a malfunction and stores a DTC.

Monitor Execution, Sequence, Duration, DTC Type 

Execution Continuous
Sequence None
Duration 0.5 second or more
DTC Type* 1 One drive cycle, MIL on
DTC Type* 2 One drive cycle, MIL off

*1: USA and Canada models*2: Mexico models

Enable Conditions 

Condition Minimum Maximum
12 volt battery voltage [Battery] 7.0 V -
Starter On
Vehicle ON mode

[ ]: HDS Parameter

Malfunction Threshold 

The ST_RLY_1_TO_2 terminal voltage level is off (high voltage) for at least 0.5 second despite the PCM outputs on to starter cut relay 1 circuit.

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* 1 

Conditions for setting the DTC 

When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, the freeze data, and the on-board snapshot are stored in the PCM memory.

Conditions for clearing the DTC 

The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, the freeze data, and the on-board snapshot can be cleared with the scan tool clear command.

Diagnosis Details* 2 

Conditions for setting the DTC 

When a malfunction is detected, a Pending DTC, a Confirmed DTC, the freeze data, and the on-board snapshot are stored in the PCM memory. The MIL does not come on.

Conditions for clearing the DTC 

The Pending DTC, the Confirmed DTC, the freeze data, and the on-board snapshot can be cleared with the scan tool clear command.
