The Lexus C1241/41 Code is a Low Battery Positive Voltage issue that affects many Lexus owners. This code typically occurs when the voltage of the relay power supply terminal (BS1) is below 8.9 V, and the actual current that is supplied by the relay does not reach the specified value at any of the linear solenoids for 0.03 seconds or more. This code can also be triggered by a variety of other causes, including low battery, ABS MAIN1 and ABS MAIN2 relays, charging system, and power source circuit. This failure type can be classified as a general checksum failure, which is used by the control module to indicate an incorrect checksum calculation where memory type is not specified.
Causes and Solutions for the Lexus C1241/41 Code
| Cause | Solution |
|---|---|
| Battery | Replace the battery, check the connections, and ensure the battery is charging properly. |
| ABS MAIN1 Relay | Check the relay and replace if necessary. |
| ABS MAIN2 Relay | Check the relay and replace if necessary. |
| Charging System | Check the wiring, tighten connections, and inspect the alternator. |
| Power Source Circuit | Inspect the wiring, tighten connections, and clean any corrosion that may be present. |
When the Lexus C1241/41 Code is triggered, it typically indicates a Low Battery Positive Voltage issue with the main relay 1 line. This code is triggered when the voltage of the relay power supply terminal (BS1) is below 8.9 V, and the actual current that is supplied by the relay does not reach the specified value at any of the linear solenoids for 0.03 seconds or more. It can also be caused by a variety of other issues, such as low battery, ABS MAIN1 and ABS MAIN2 relays, charging system, and power source circuit. The Lexus C1241/41 Code can be classified as a general checksum failure, which is used by the control module to indicate an incorrect checksum calculation where memory type is not specified. The most effective way to resolve the issue is to identify the root cause, and then take appropriate action to address it.
Battery
If the Lexus C1241/41 Code is caused by a low battery, the first step is to replace the battery. It is important to check the connections, and ensure that the battery is charging properly. Additionally, it is necessary to ensure that the charging system is in good working order.
ABS MAIN1 and ABS MAIN2 Relays
If the Lexus C1241/41 Code is triggered by either the ABS MAIN1 or ABS MAIN2 relays, it is important to check the relays and replace them if necessary. It is also important to inspect the wiring, and ensure that all connections are properly tightened.
Charging System
If the Lexus C1241/41 Code is caused by a malfunctioning charging system, the first step is to inspect the wiring and tighten any loose connections. Additionally, it is important to inspect the alternator to ensure that it is in good working order.
Power Source Circuit
If the Lexus C1241/41 Code is caused by a power source circuit issue, it is important to inspect the wiring and clean any corrosion that may be present. Additionally, it is necessary to ensure that all connections are properly tightened.
Conclusion
In conclusion, the Lexus C1241/41 Code is a Low Battery Positive Voltage issue that can be caused by a variety of issues, including low battery, ABS MAIN1 and ABS MAIN2 relays, charging system, and power source circuit. The most effective way to resolve the issue is to identify the root cause and take appropriate action to address it. Using the proper diagnostic tools and techniques, any professional mechanic should be able to diagnose and repair the Lexus C1241/41 Code in a timely and efficient manner.
