Circuit Description

The engine control module (ECM) supplies a ground path for the starter relay when start enable has been requested. The ECM monitors this circuit for conditions that are incorrect for the commanded state. If the ECM detects an improper circuit condition, starter relay DTC P0617 will set.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC P0617 Starter Relay Control Circuit High Voltage

Conditions for Running the DTC
    • System voltage is between 8-16 volts.
    • The engine is running.

Conditions for Setting the DTC
    • The ECM detects an improper voltage level on the output circuit that controls the CRANK relay.
    • The condition exists for at least 2 seconds.

Action Taken When the DTC Sets
    • The ECM will not illuminate the malfunction indicator lamp (MIL).
    • The ECM will store the conditions present when the DTC set as Fail Records data only.

Conditions for Clearing the MIL/DTC
    • The history DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction.
    • The DTC can be cleared by using the scan tool Clear DTC Information function.
