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.

E1 CHECK THE ACCESSORY DELAY RELAY
- Disconnect: Accessory Delay Relay
- Carry out the Accessory Delay Relay Component Test. Refer to COMPONENT TESTING.
- Did the accessory delay relay pass the component test?
1. YES : Go to E2.
2. NO : INSTALL a new accessory delay relay. TEST the system for normal operation.
E2 CHECK CIRCUIT 964 (DB/LG) FOR A SHORT TO VOLTAGE
- Key in ON position.
- Measure the voltage between accessory delay relay pin 87, circuit 964 (DB/LG), harness side and ground.
- Is any voltage present?
1. YES : REPAIR the circuit. TEST the system for normal operation.
2. NO : Go to E3.
E3 CHECK CIRCUIT 1004 (LB/RD) FOR A SHORT TO GROUND
- Key in OFF position.
- Disconnect: IC C220B
- Measure the resistance between accessory delay relay pin 85, circuit 1004 (LB/RD) and ground.
- Is the resistance greater than 10,000 ohms?
1. YES : INSTALL a new IC. REFER to INSTRUMENT CLUSTER (IC) AND WARNING CHIMES article. TEST the system for normal operation.
2. NO : REPAIR the circuit. TEST the system for normal operation.
