Open-Circuit in Signal Cable or Ground Lead
When the Volvo Code ECC-124 is triggered, it is often due to an open circuit in the signal cable or ground lead. This can occur when the cable or lead has been damaged or the connections have been weakened over time. To fix this issue, it is essential to inspect the wiring for any open-circuit issues, and repair or replace the cable or lead if necessary.
Short-Circuit to Battery Voltage in the Signal Cable or Ground Lead
Another potential cause of Volvo Code ECC-124 is a short circuit to battery voltage in the signal cable or ground lead. This can occur when the cable or lead has been damaged, or the connections have been weakened over time. To fix this issue, it is essential to inspect the cable or lead for any short-circuit issues, and make the appropriate repairs or replacements.
Contact Resistance in Terminals
In some cases, Volvo Code ECC-124 may be triggered by contact resistance in the terminals. This can occur when the terminals are not correctly connected, or when the connections have been weakened over time. To fix this issue, it is essential to verify that the terminals are correctly connected with no signs of contact resistance and replace the terminals if necessary.
Defective Temperature Sensor
The last possible cause of Volvo Code ECC-124 is a defective temperature sensor. This can occur when the sensor has been damaged or malfunctioned, or when the connections have been weakened over time. To fix this issue, it is essential to test the temperature sensor for any signs of damage or malfunction and replace the sensor if necessary.
