DTC U210C: LOST COMMUNICATION BETWEEN FUEL PUMP CONTROL MODULE B AND RESTRAINTS CONTROL MODULE
| Description: | The fuel pump control module 2 monitors the duty cycle and frequency of the signal it receives from the restraints control module (RCM). The fuel pump control module 2 determines if the signal on the event notification signal (ENS) circuit from the RCM is a valid duty cycle and frequency. If the duty cycle or frequency is invalid, the fuel pump control module 2 sends a 40% duty cycle signal on the fuel pump monitor 2 (FPM2) circuit to report the concern to the PCM. The test fails when the fuel pump control module 2 is still reporting that it is receiving an invalid duty cycle or frequency from the RCM after a calibrated amount of time. | ||
| Possible Causes: |
|
||
| Diagnostic Aids: | Check the harness for routing, alterations, incorrect shielding, or electrical interference from other systems. The ENS is used to notify the fuel pump control module 2 of an event requiring the fuel pump to be disabled. This signal is used instead of an inertia fuel shutoff (IFS) switch. The fuel pump control module 2 monitors the ENS signal by sending a 12V low current signal on the ENS circuit to the RCM. | ||

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
