Code U0469 Lincoln Description
- The first thing to check is if the battery is the correct type. Smart charge systems are designed to be used only with a silver calcium battery not the lead acid type due to the voltages used which may damage a lead acid battery and give incorrect readings.
- If you disconnect the 3 pin PCM plug from the alternator and it is charging again, this will show the alternator is being controlled by the PCM. This will check if the alternator is still functioning. The 3 pin plug will need to be reconnected immediately after the test to avoid any damage to the vehicle. This test is a temporary check only and is not a resolution to the fault. Disconnection and reconnection of the 3 pin plug should be done when the engine is switched off.
If the battery is of the correct type and the alternator is found to be charging, the next part to check is the continuity of the wiring loom from the alternator to the PCM. Due to the location of the alternator in relation to the PCM, the wiring can become chafed or the insulation melts from being too close to a heat source. This is a common reason when the battery light is illuminated and a new loom will be needed.
