DTC P058E: Battery Monitor Module Temperature Too High: Notes
DTC detecting condition:
Immediately at fault recognition
- CHECK DTC
.
- Turn the ignition switch to ON.
- Using the Subaru Select Monitor or a general scan tool, read the DTC of [Engine]. Ref. to COMMON (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
Is DTC P058A displayed? (Current code or history code)
Yes: Check for DTC P058A. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC)>DTC P058A BATTERY MONITOR MODULE PERFORMANCE .
No: Go to 2.
- CHECK FREEZE FRAME DATA
.
Using the Subaru Select Monitor, read the values in [Battery Terminal Voltage], [Battery Charge/Discharge Current] and [Estimated Battery Temperature].
NOTE: For detailed operation procedures, refer to "COMMON (DIAGNOSTICS)". Ref. to COMMON (DIAGNOSTICS)>FREEZE FRAME DATA .Is [Battery Terminal Voltage] 14.3 V, is [Battery Charge/Discharge Current] 0 A, and is [Estimated Battery Temperature] 20°C (68°F)? (Check the value that is before confirming malfunction)
NOTE: If it is fixed to the failsafe value ([Battery Terminal Voltage]: 14.3 V, [Battery Charge/Discharge Current]: 0 A, [Estimated Battery Temperature]: 20°C (68°F)) before confirming malfunction, it can be judged that DTC was detected due to malfunction occurrence during self-diagnosis of the battery sensor. Therefore, check P058A.Yes: Check for DTC P058A. Ref. to ENGINE (DIAGNOSTICS) (H4DO)>DIAGNOSTIC PROCEDURE WITH DIAGNOSTIC TROUBLE CODE (DTC)>DTC P058A BATTERY MONITOR MODULE PERFORMANCE .
No: Go to 3.
- CHECK DTC
.
Using the Subaru Select Monitor or a general scan tool, read the DTC of [Engine]. Ref. to COMMON (DIAGNOSTICS)>DIAGNOSTIC TROUBLE CODE (DTC) .
Is DTC P058E displayed? (Current code)
Yes: Replace the battery sensor. Ref. to STARTING/CHARGING SYSTEMS (H4DO)>BATTERY SENSOR .
No: Even if DTC is detected, it has returned to a normal condition at this time. Reproduce the failure, and then perform the diagnosis again.
