Code P1B98 Saturn Description

The Hybrid/Electric Vehicle battery pack contains 288 cells. Groups of three cells are welded together in parallel. There are a total of 96 cell groups in the hybrid/EV battery pack assembly. These cell groups are electrically connected in-series. Each individual cell group is rated at 3.7 V, for a nominal system voltage of 355 V direct current. The battery cells are also grouped together into three sections. The first 90 cells/30 cell groups make up battery section one. This section is adjacent to the cowl and contains batteries 67 through to 96. Battery section two is located behind section one. It is made up of 72 cells/24 cell groups and contains batteries 43 through to 66. The transverse battery section is section number three, it is made up of the remaining 126 cells/42 cell groups and contains batteries 1 through to 42. The three battery sections are individually serviceable components.
The battery energy control module monitors the voltage of the 96 battery cell groups through the four hybrid/EV battery interface control modules. Voltage sense circuits are attached to each individual cell group, and these sense circuits terminate at a connector located on the top surface of the battery section. A serviceable auxiliary battery wiring harness joins this connector to a hybrid/EV battery interface control module, also located on the top surface of the battery section. The hybrid/EV battery interface control module encodes the voltage reading and transmits it to the battery energy control module through the battery control harness. There is one hybrid/EV battery interface control module located on battery sections one and two, and two hybrid/EV battery interface control modules associated with battery section three. The hybrid/EV battery interface control module, battery energy control module wiring harness, auxiliary battery wiring harness, and battery energy control module are all considered serviceable components.
The battery energy control module will determine when a fault condition is present. Diagnostics and system status are communicated from the battery energy control module to hybrid/EV powertrain control module 2 through serial data. The hybrid/EV powertrain control module 2 is the host controller for diagnostic trouble code information.

Frequently Asked Questions about P1B98 Saturn Code

1. What does the OBDII code P1B98 mean on a Saturn?

P1B98 indicates a "Hybrid/Electric Vehicle Battery 60 Circuit High Voltage," meaning the vehicleâ€™s control module has detected an abnormally high voltage in the battery circuit 60.

2. What are the common symptoms of the P1B98 code?

Symptoms may include an illuminated check engine light, reduced hybrid/electric vehicle performance, failure to start, or warning messages about the battery system.

3. What causes the P1B98 code on a Saturn?

Possible causes include a faulty hybrid battery pack, damaged or corroded wiring, a malfunctioning battery control module, or a defective high-voltage connector.

4. Can I drive my Saturn with the P1B98 code?

Driving with this code is not recommended, as it can lead to further damage to the hybrid battery system or cause the vehicle to go into limp mode.

5. How is the P1B98 code diagnosed?

A technician will use a scan tool to read the code, inspect the high-voltage wiring and connectors, test the battery pack, and check the battery control module for faults.

6. How can I fix the P1B98 code on my Saturn?

Repairs may involve replacing the hybrid battery pack, repairing or replacing damaged wiring, or replacing the battery control module if itâ€™s faulty.

7. What is the cost to fix the P1B98 code on a Saturn?

Repair costs vary, but they can range from $200 for wiring repairs to $3,000 or more for hybrid battery replacement, depending on the extent of the issue.

8. Can a low auxiliary (12V) battery cause the P1B98 code?

No, this code is specific to the high-voltage hybrid battery system and is unrelated to the auxiliary 12V battery.

9. Do I need specialized tools to repair the P1B98 code?

Yes, hybrid systems require specialized tools and training due to the high voltage involved, so itâ€™s best to leave repairs to a qualified technician.

10. Can ignoring the P1B98 code damage my vehicle?

Yes, ignoring this code can lead to further damage to the hybrid battery system and potentially render the vehicle inoperable.
