Pinpoint Test F: The Battery Saver Does Not Deactivate After Time-Out

WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

F1 CHECK CIRCUIT 54 (LG/YE) FOR A SHORT TO VOLTAGE
- Disconnect: Battery Saver Relay
- Turn a demand lamp on.
- Does the demand lamp illuminate?
1. YES : REPAIR the circuit. TEST the system for normal operation.
2. NO : Go to F2.
F2 CHECK CIRCUIT 1005 (VT/OG) FOR A SHORT TO GROUND
- Key in OFF position.
- Disconnect: IC C220a
- Measure the resistance between the IC C220a-1, circuit 1005 (VT/OG), harness side and ground.
- Is the resistance greater than 10,000 ohms?
1. YES : Go to F3.
2. NO : REPAIR the circuit. TEST the system for normal operation.
F3 CHECK THE BATTERY SAVER RELAY FOR CORRECT OPERATION
- Connect: IC C220a
- Install a known good relay.
- Does the demand lamp illuminate?
1. YES : REMOVE the known good relay. Go to F4.
2. NO : REMOVE the known good relay. INSTALL a new battery saver relay. TEST the system for normal operation.
F4 CHECK FOR CORRECT IC OPERATION
- Key in OFF position.
- Disconnect all the IC connectors.
- Check for:
  - corrosion
  - damaged pins
  - pushed-out pins
- Connect all the IC connectors and make sure they seat correctly.
- Operate the system and verify the concern is still present.
- Is the concern still present?
1. YES : INSTALL a new IC. REFER to INSTRUMENT CLUSTER (IC) AND WARNING CHIMES article. TEST the system for normal operation.
2. NO : The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
