Pinpoint Test Ag: DTC U3003:16 (FCIM)

NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to BATTERY, MOUNTING AND CABLES .

AG1 RECHECK THE FCIM DTCs
- Ignition ON.
- Clear the FCIM DTCs.
- Wait at least 15 seconds.
- Repeat the FCIM self-test.
- Is DTC U3003:16 still present?
- Yes: GO to AG2 .
- No: The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.
AG2 CHECK FOR CHARGING SYSTEM DTCs IN THE PCM
- Retrieve the continuous DTCs from all modules.
- Is DTC P0620, P0622, P0625, or P065B set in the PCM?
- Yes: REFER to CHARGING SYSTEM .
- No: GO to AG3 .
AG3 CHECK THE BATTERY CONDITION AND STATE OF CHARGE
- Check the battery condition and verify that the battery is fully charged. Refer to BATTERY, MOUNTING AND CABLES .
- Is the battery OK and fully charged?
- Yes: GO to AG4 .
- No: REFER to BATTERY, MOUNTING AND CABLES .
AG4 CHECK THE FCIM VOLTAGE SUPPLY
- Ignition OFF.
- Measure and record the voltage at the battery.
- Disconnect: FCIM C2402 (Without Navigation) or C2403 (With Navigation).
- Ignition ON.
- For vehicles without navigation, measure the voltage between the FCIM C2402-1, circuit SBP16 (VT/RD), harness side and ground.

- Is the voltage at the FCIM within 0.2 volt of the recorded battery voltage?
- Yes: GO to AG5 .
- No: REPAIR the circuit for high resistance. CLEAR the DTCs. REPEAT the self-test.
AG5 CHECK THE FCIM GROUND CIRCUIT
- Ignition OFF.
- Disconnect: Negative Battery Cable.
- For vehicles without navigation, measure the resistance between the FCIM C2402-4, circuit GD114 (BK/BU), harness side and ground.

- Is the resistance less than 5 ohms?
- Yes: GO to AG6 .
- No: REPAIR the circuit for high resistance. CLEAR the DTCs. REPEAT the self-test.
AG6 CHECK FOR CORRECT FCIM OPERATION
- Ignition OFF.
- Connect: Negative Battery Cable.
- Disconnect the FCIM connector.
- Check for:
  - corrosion
  - damaged pins
  - pushed-out pins
- Connect the FCIM connector and make sure it seats correctly.
- Operate the system and determine if the concern is still present.
- Is the concern still present?
- Yes: INSTALL a new FCIM . REFER to FRONT CONTROLS INTERFACE MODULE (FCIM) - WITHOUT NAVIGATION or FRONT CONTROLS INTERFACE MODULE (FCIM) - WITH NAVIGATION . TEST the system for normal operation.
- No: The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
