WARNING: This page is about a different variant/trim than selected.
The following table illustrates the ECM connector locations:
| ECM Connector Location | |

| X2 | X1 |
| Front of Vehicle | |
- When the ECM commands the powertrain relay ON, ignition voltage is supplied to the following fuses in the underhood fuse block:
- ELEK IGN Fuse
- ETC Fuse
- FUEL INJ Fuse
- O2 SSR Fuse
- This test procedure requires that the vehicle battery has passed a load test and is completely charged. Refer to Battery Inspection/Test .
- An open in the relay control circuit will cause no communication with the ECM when the ignition switch is cycled OFF and ON after the initial failure. The malfunction indicator lamp (MIL) will flash rapidly and other relays can be heard turning on and off with the ignition ON.
- When disconnecting electrical connectors or removing fuses and relays from a fuse block, always inspect the component electrical terminals for corrosion and the mating electrical terminals for tightness.
- Operate the vehicle within the conditions for running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that are captured in the Freeze Frame/Failure Records Data List.
