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 P0616 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 starter 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 Failure 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. |
Step | Action | Yes | No |

Does the scan tool indicate that DTC P0617 has passed this ignition cycle? | Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems | Go to Step 3 |
3 | Test the control circuit of the starter relay for a short to battery. Refer to Circuit Testing and Wiring Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 6 | Go to Step 4 |
4 | Inspect for poor connections at the engine control module (ECM). Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition? | Go to Step 6 | Go to Step 5 |
5 | Replace the ECM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the replacement? | Go to Step 6 | -- |
6 |
Does the scan tool indicate that DTC P0617 failed this ignition? | Go to Step 2 | System OK |
