DIAGNOSTIC PROCEDURES - P0615-STARTER RELAY CIRCUIT EXCESSIVE CURRENT
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 |
NOTE:
If the ECM detects and stores a DTC, the ECM also stores the engine/vehicle operating conditions under which the DTC was set. Some of these conditions are displayed on the DRB at the same time the DTC is displayed.
NOTE:
Before erasing stored DTCs, record these conditions. Attempting to duplicate these conditions may assist when checking for an active DTC. Turn the ignition on.With the DRB, erase ECM DTCs.Attempt to start the engine several times, pausing for at least 10 seconds between each attempt.Turn the ignition on.With the DRB, read ECM DTCs.Did this DTC set again?Yes --> Go To 2No --> Go To 7 |

| 2 | Turn the ignition off. Install a substitute relay in place of the Starter Relay. Turn the ignition on. With the DRBIII®, erase DTCs. Attempt to start the engine several times, pausing for at least 10 seconds between each attempt. Turn the ignition on. With the DRB, read ECM DTCs. Did this DTC set again? Yes --> Go To 3 No --> Replace the Starter Relay. Perform ROAD TEST VERIFICATION - VER-2 . |
All |
| 3 | Turn the ignition off. Remove the Starter Relay from the PDC. Disconnect the ECM harness connectors. Turn the Ignition Switch to the Start position. Using a 12-volt test light connected to ground, check the Ignition Switch Start Output circuit at the Starter Relay connector in the PDC. Using a 12-volt test light connected to ground, check the Ignition Switch Start Output circuit at the ECM C2 harness connector cavity 22. Does the test light illuminate brightly for both circuit checks? Yes --> Go To 4 No --> Repair the Ignition Switch Start Output circuit for an open. Perform ROAD TEST VERIFICATION - VER-2 . |
All |
| 4 | Turn the ignition off. Remove the Starter Relay from the PDC. Disconnect the ECM harness connectors. Measure the resistance of the Starter Relay Control circuit between the ECM harness connector and the PDC connector. Is the resistance below 10.0 ohms? Yes --> Go To 5 No --> Repair the Starter Relay Control circuit for an open. Perform ROAD TEST VERIFICATION - VER-2 . |
All |
| 5 | Turn the ignition off. Remove the Starter Relay from the PDC. Disconnect the ECM harness connectors. Measure the resistance between ground and the Starter Relay Control circuit. Is the resistance above 1000 ohms? Yes --> Go To 6 No --> Repair the Starter Relay Control circuit for a short to ground. Perform ROAD TEST VERIFICATION - VER-2 . |
All |
| 6 | Turn the ignition off. Remove the Starter Relay. Disconnect the ECM harness connectors. Remove the ASD Relay from the PDC. Connect a jumper wire between cavity 30 and cavity 87 of the ASD Relay connector. Turn the ignition on. Measure the voltage of the Starter Relay Control circuit. Is the voltage below 1.0 volt? Yes --> Replace and program the Engine Control Module in accordance with the Service Information. Perform ROAD TEST VERIFICATION - VER-2 . No --> Repair the Starter Relay Control circuit for a short to voltage. Perform ROAD TEST VERIFICATION - VER-2 . |

WARNING:
WHEN THE ENGINE IS OPERATING, DO NOT STAND IN A DIRECT LINE WITH THE FAN. DO NOT PUT YOUR HANDS NEAR THE PULLEYS, BELTS OR FAN. DO NOT WEAR LOOSE CLOTHING.
NOTE:
The conditions that set the DTC are not present at this time. The following list may help in identifying the intermittent condition. With the engine running at normal operating temperature, monitor the DRB parameters related to the DTC while wiggling the wiring harness. Look for parameter values to change and/or a DTC to set.Review the DTC When Monitored and Set Conditions. If possible, try to duplicate the conditions under which the DTC was set.Refer to any Technical Service Bulletins (TSB) that may apply.Visually inspect the related wiring harness. Look for any chafed, pierced, pinched, or partially broken wires.Visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals.Were any of the above conditions present?Yes --> Repair as necessary.Perform ROAD TEST VERIFICATION - VER-2 .No --> Test Complete. |
