P0615-STARTER RELAY CIRCUIT EXCESSIVE CURRENT

For a complete wiring diagram Refer to Section 8W

When Monitored:
With the ignition on and the ECM Starter Relay command on.
Set Condition:
The ECM detects excessive current on the Starter Relay Control circuit for 0.2 seconds.

Possible Causes

INTERMITTENT CONDITION

STARTER RELAY

IGNITION SWITCH START OUTPUT OPEN

STARTER RELAY CONTROL CIRCUIT OPEN

STARTER RELAY CONTROL CIRCUIT SHORTED TO GROUND

STARTER RELAY CONTROL CIRCUIT SHORTED TO VOLTAGE

ENGINE CONTROL MODULE

Diagnostic Test

1.CLEAR CODE AND CHECK IF THE DTC RESETS

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 scan tool 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.

Did this DTC set again?

Yes

Go To2

Refer to the *CHECKING FOR AN INTERMITTENT DTC Diagnostic Procedure. (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING)

2.STARTER RELAY

Did this DTC set again?

Yes

Go To3

Replace the Starter Relay.
Perform the ECM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).

3.IGNITION SWITCH START OUTPUT CIRCUIT OPEN

Does the test light illuminate brightly for both circuit checks?

Yes

Go To4

Repair the Ignition Switch Start Output circuit for an open.
Perform the ECM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).

4.STARTER RELAY CONTROL CIRCUIT OPEN

Is the resistance below 10.0 ohms?

Yes

Go To5

Repair the Starter Relay Control circuit for an open.
Perform the ECM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).

5.STARTER RELAY CONTROL CIRCUIT SHORTED TO GROUND

Is the resistance above 1000 ohms?

Yes

Go To6

Repair the Starter Relay Control circuit for a short to ground.
Perform the ECM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).

6.STARTER RELAY CONTROL CIRCUIT SHORTED TO VOLTAGE

Is the voltage below 1.0 volt?

Yes

Replace and program the Engine Control Module in accordance with the Service Information.
Perform the ECM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).

Repair the Starter Relay Control circuit for a short to voltage.
Perform the ECM Verification Test Ver. 1 (Refer to 9 - ENGINE - DIAGNOSIS AND TESTING).
