Pinpoint Test B: A Virtual Gauge Is Inoperative (Fuel Or Temperature)
- Normal Operation and Fault Conditions
See Gauges. Refer to Instrument Panel Cluster (IPC) - System Operation and Component Description .
Fuel Gauge
- If the IPC does not receive the fuel level input for less than 33 seconds, the IPC defaults the fuel gauge to the last indication state based on the last input received.
Temperature Gauge
- If the engine coolant temperature data or engine overheat indication request messages are missing for less than 5 seconds, the IPC defaults the temperature gauge to the last indication state, based upon the last message received.
- If the engine coolant temperature data or engine overheat indication request messages are missing for 5 seconds or longer, the IPC defaults the temperature gauge to the full hot position.

- B1 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Using a diagnostic scan tool, perform the IPC self-test.
- Check for recorded Diagnostic Trouble Codes (DTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes Refer to Diagnostic Trouble Code (DTC) Chart No GO to B2 - B2 PERFORM THE PCM (POWERTRAIN CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, perform the PCM self-test.
- Check for recorded Diagnostic Trouble Codes (DTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes For 1.5L, Refer to Electronic Engine Controls 1.5L EcoBoost . For 2.0L, Refer to Electronic Engine Controls 2.0L EcoBoost . No GO to B3 - B3 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, check the GWM Continuous Memory Diagnostic Trouble Codes (DTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes Refer to Communications Network . No GO to B4 - B4 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION
- Ignition OFF.
- Disconnect and inspect the IPC connector.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the IPC connector. Make sure it seats and latches correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
Yes CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new IPC. Refer to Instrument Panel Cluster (IPC) . No The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
