Normal Operation and Fault Conditions
WARNING: This page is about a different car, the 2019 Ford F-550 Super Duty, 2019 Ford F-450 Super Duty, 2019 Ford F-350 Super Duty, and 2019 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.
The ABS module carries out self tests during operation, the module also monitors various inputs and compares the values to what should be expected. If the values received are out of range, are not what is expected, or if any of the self tests fail, the ABS module sets a DTC.
DTC DESCRIPTION
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| C1A76:49 | Valve Relay: Internal Electronic Failure | This DTC sets when the valve relay circuit feedback does not match the commanded state. |
| C1A77:11 | Valve Relay Supply Circuit: Circuit Short To Ground | This DTC sets when the monitoring detects UVR voltage compared to the UBVR voltage indicates the valve relay has a high impedance short to ground. |
| P0604:94 | Internal Control Module Random Access Memory (RAM) Error: Unexpected Operation | This DTC sets when software execution attempts to access RAM addresses outside specified allowable range. |
| P062F:46 | Internal Control Module EEPROM Error: Calibration/Parameter Memory Failure | This DTC sets when a value is written by the ABS module is written to EEPROM but the value read back is not correct |
| U2007:49 | Valve(s): Internal Electronic Failure | This DTC sets due to an electrical failure (open circuit, short to ground, short to voltage) in one or more of the HCU valve coils. |
| U3000:00 | Control Module: No Sub Type Information | Sets when the ABS module detects an internal fault. |
| U3000:44 | Control Module: Data Memory Failure | Sets when the ABS module detects an internal fault. |
| U3000:45 | Control Module: Program Memory Failure | Sets when the ABS module detects an internal fault. |
| U3000:46 | Control Module: Calibration/Parameter Memory Failure | Sets when the ABS module detects an internal fault. |
| U3000:47 | Control Module: Watchdog/Safety Micro-Controller Failure | Sets when the ABS module detects an internal fault. |
| U3000:48 | Control Module: Supervisor Software Failure | Sets when the ABS module detects an internal fault. |
| U3000:49 | Control Module: Internal Electronic Failure | Sets when the ABS module detects an internal fault. |
| U3000:4B | Control Module: Over Temperature | Sets when the ABS module detects excessive temperature within the ABS module. |
