# Service bulletin 0809221

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Flash: Battery Pack Control Module \(BPCM\) Diagnostic and System Updates This bulletin involves updating the BPCM with the latest available software. Customers may experience a Malfunction Indicator Lamp \(MIL\) illumination. Upon further investigation, the technician may notice one or more of the following Diagnostic Trouble Codes \(DTCs\) have been set: P0AA1\-00 \- Hybrid/Ev Battery Positive Contactor ?A? Stuck Closed. P0AA4\-00 \- Hybrid Battery Negative Contactor Circuit Stuck Closed. P0B3C\-00 \- Hybrid\-Ev Battery Voltage Sense 1 Circuit Performance. P0B41\-00 \- Hybrid\-Ev Battery Voltage Sense 2 Circuit Performance. P0B46\-00 \- Hybrid\-Ev Battery Voltage Sense 3 Circuit Performance P0B4B\-00 \- Hybrid\-Ev Battery Voltage Sense 4 Circuit Performance. P0B50\-00 \- Hybrid/Ev Battery Voltage Sense 5 Circuit Performance. P0B55\-00 \- Hybrid/Ev Battery Voltage Sense 6 Circuit Performance. Engine will run in fuel oil refresh mode often and customer may be prompted to get an oil change before needed. Software corrects real time clock synchronization with Powertrain Control Module \(PCM\) and BPCM. In the previous software, after a battery replacement, the timing for when an oil\&fuel change was due was reset to zero, instead of being dependent on the mileage. All new replacements packs will receive this software update.
