Circuit Description
The engine control module (ECM) supplies a ground path for the CRANK 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 P0616 Starter Relay Control Circuit Low 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. |
Step | Action | Yes | No |

1 | Did you perform the Diagnostic System Check - Vehicle? | Go to Step 2 | |
2 |
Does the scan tool indicate that DTC P0616 has passed this ignition cycle? | Go to Testing for Intermittent Conditions and Poor Connections | Go to Step 3 |
3 | Test the control circuit of the CRANK relay for a short to ground. Refer to Circuit Testing and Wiring Repairs . 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 . Did you find and correct the condition? | Go to Step 6 | Go to Step 5 |
5 | Replace the ECM. Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement? | Go to Step 6 | -- |
6 |
Does the scan tool indicate that DTC P0616 failed this ignition? | Go to Step 2 | System OK |
