CSM 523746.04 — Cab Switch Module Wake-up Output Voltage Low
CSM 523746.04 (CSM )
Code: 523746.04
Shortcode:
Description:
This error code, CSM 523746.04, indicates that the 12 V output from the Cab Switch Module (CSM) to the Cab Load Center (CLC) is too low. This could be due to issues with the CSM, wiring problems, or a malfunctioning power supply.
Reaction:
The wake-up function of the CSM is disabled, preventing the system from properly powering up.
Recommendations:
Inspect CSM Output:
- Verify the 12 V output from the CSM to the CLC using a multimeter. Check for any discrepancies in the voltage.
Check Wiring and Connections:
- Inspect the wiring and connections between the CSM and CLC for any signs of damage, loose connections, or corrosion. Secure and clean all connections to ensure proper electrical contact.
Evaluate Power Supply:
- Ensure that the power supply to the CSM is functioning correctly. Replace or repair the power supply if it is causing low output voltage.
Test CSM Functionality:
- Perform diagnostic tests on the CSM to ensure it is operating correctly. Replace the CSM if it is found to be defective.
Reset and Test System:
- After addressing the issue, reset the system and conduct tests to ensure the wake-up output voltage is within the acceptable range and that the CSM function is restored.
Note:
Maintaining proper output voltage from the CSM to the CLC is essential for the reliable wake-up function of the system. Regular inspections and maintenance of the CSM, wiring, and power supply can help prevent low voltage issues.
