Step 1: Check the Glow Plugs

The first step in fixing the P1401 Glow Plug Monitor Fault (Bank #2) is to check the glow plugs. Glow plugs are responsible for heating the air in the combustion chamber, which is necessary for starting the engine. If the glow plugs are not working properly, the engine may not start or may run poorly. To check the glow plugs, you will need a multimeter. Set the multimeter to the ohms setting and touch the probes to the glow plug terminals. If the reading is less than 1 ohm, the glow plug is working properly. If the reading is higher than 1 ohm, the glow plug needs to be replaced.

If the resistance is higher than it should be, the wiring needs to be repaired or replaced.

Step 3: Check the Glow Plug Control Module

If the glow plugs and wiring are working properly, the next step is to check the glow plug control module. The glow plug control module is responsible for controlling the glow plugs and can become damaged over time. To check the glow plug control module, you will need to use a scan tool. Use the scan tool to check for any fault codes related to the glow plug control module. If there are no fault codes, the control module is working properly. If there are fault codes, the control module needs to be replaced.

Step 4: Replace the Glow Plug Control Module

If the glow plug control module needs to be replaced, you will need to remove the old module and install a new one. The glow plug control module is typically located near the engine and can be accessed by removing a few bolts. Once the old module is removed, install the new module and reconnect any wiring that was disconnected.

Step 5: Clear the Fault Code

After replacing the glow plug control module, you will need to clear the fault code. Use a scan tool to clear the fault code and start the engine. If the engine starts and runs properly, the P1401 Glow Plug Monitor Fault (Bank #2) has been fixed.
