Hi, as the title suggests, I had my Fiesta out over the winter, I started it a few times over winter with no issues. However, now spring is here, I get the following codes:
P0689
Definition:
ECM/PCM Power Relay Sense Circuit Low
Description:
This DTC sets when the ISP-R and the INJPWRM circuit voltages do not correspond for a calibrated period of time.
Cause:
- Ignition circuit fuse
- ISP-R circuit open
- ISP-R circuit short to ground
- VPWR circuit short to voltage
- INJPWR circuit short to voltage
- Damaged ignition switch
- Damaged fuel pump relay
- Damaged PCM power relay
Diagnosis:
The INJPWRM PID voltage reading should be 0 volts when the ignition is in the OFF, ACC or LOCK position.
P2510
Definition:
ECM / PCM Power Relay Sense Circuit Range/Performance
Description:
The ISP-R and the INJPWRM circuits are monitored for correlation. This DTC sets when the voltage on the ISP-R and the INJPWRM circuit voltages do not correspond for a calibrated period of time.
Cause:
- Ignition circuit fuse
- ISP-R circuit open
- ISP-R circuit short to ground
- Fuel injector VPWR circuit short to voltage
- Fuel injector INJPWR circuit short to voltage
- Damaged ignition switch
- Damaged fuel pump relay
- Damaged PCM power relay
Diagnosis:
The INJPWRM PID voltage reading should be 0 volts when the ignition is in the OFF, ACC or LOCK position.
P0562
Definition:
System Voltage Low: No Sub Type Information
Cause:
This DTC sets wsets when the TCCM detects less than 9 volts of battery voltage for 5 seconds or more at TCCM .Failure Type:No Sub Type InformationThis sub type is used for failures where the base DTC text string provides the complete description of the failure itself (no Category and no Sub Type information used, e.g. emissions-related DTC (012700 hex): P0127 Intake Air Temperature Too High).
P2610
Definition:
ECM/PCM Engine Off Timer Performance
Description:
This DTC sets when an error in the internal PCM engine off timer processor occurs.Cause:
- KAPWR circuit open
- KAPWR circuit short to ground
- Battery cables loose
- Intermittent battery cable connections
- Engine cooling system concerns
- Damaged Engine Coolant Temperature (ECT) sensor
Diagnosis:
Verify the PCM is at the latest calibration level.

I have replaced the battery and was getting about 3Amps of current draw when the car was idle. I traced this to F32 a 20Amp fuse for BCM – battery saver, horn.
However, after charging the battery to 100%. I still get those PCM codes.
Any ideas on the next troubleshooting steps?
