Relay NO. | Relay Name | Type |
1 | ENGINE CONTROL RELAY | PCB |
2 | A/C COMP RELAY (SPARE) | PCB |
3 | F/PUMP RELAY | PCB |
The PCM provides ground to one side of the coil in the fuel pump relay to control the fuel pump relay. The other side of the fuel pump relay coil is connected to fuel pump relay, which activates when the ignition switch is ON. The PCM monitors the control circuit between the fuel pump relay and the PCM. When the ignition switch is turned ON, the PCM energizes the fuel pump relay, which sends power to the fuel pump.
PCM sets DTC P0230 if the PCM detects the fuel pump relay control circuit is open, short to ground or battery.
