Test Procedure

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Ford RV Cutaway, 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.

A1 DIAGNOSTIC TROUBLE CODES (DTCS) P0562 OR P0563

NOTE: DTC P0563 may set during a 24-volt jump start. DTC P0562 may set during crank with a low battery condition.

Check the battery and charging system voltages. Refer to CHARGING SYSTEM - GENERAL INFORMATION .

Are the battery and charging system voltages within specifications?

Yes	No
GO to A2	REPAIR as necessary. REFER to CHARGING SYSTEM - GENERAL INFORMATION . CLEAR the DTCs. REPEAT the self-test.

A2 CHECK THE PCM POWER RELAY VOLTAGE CIRCUITS

NOTE: For E-Series, the PCM diode is internal to the battery junction box (BJB).

Key in OFF position.
PCM Power Relay connector disconnected.
Key ON, engine OFF.

Measure the voltage between:

( + ) PCM Power Relay Connector, Harness Side	( - )
B+	Ground
IGN START/RUN	Ground

Are the voltages greater than 10 V?

Yes	No
GO to A3.	REPAIR the open circuit. CLEAR the DTCs. REPEAT the self-test.

A3 CHECK THE PCM POWER RELAY COIL GROUND CIRCUIT

NOTE: For F-Super Duty, the PCM diode is internal to the central junction box (CJB).

Connect a non-powered test lamp between:

( + ) PCM Power Relay Connector, Harness Side	( - ) PCM Power Relay Connector, Harness Side
B+	GND

Does the test lamp illuminate?

Yes	No
GO to A4.	REPAIR the open circuit. CLEAR the DTCs. REPEAT the self-test.

A4 CHECK THE PCM POWER RELAY

Carry out the PCM power relay component test. Refer to COMPONENT TESTING .

Does the PCM power relay pass the component test?

Yes	No
GO to A5.	INSTALL a new PCM Power relay. CLEAR the DTCs. REPEAT the self-test.

A5 CHECK THE PCM VOLTAGE CIRCUITS FOR AN OPEN

Key in OFF position.
PCM connector disconnected.

Measure the resistance between:

( + ) PCM Power Relay Connector, Harness Side	( - ) PCM Connector, Harness Side
VPWR	VPWR - Pin B34, B46

Are the resistances less than 5 ohms?

Yes	No
GO to A6.	REPAIR the open circuit. CLEAR the DTCs. REPEAT the self-test.

A6 CHECK THE PCM GROUND CIRCUITS FOR AN OPEN

Measure the resistance between:

( + ) PCM Connector, Harness Side	( - )
PWRGND - Pin B10, B11, B23	Ground

Are the resistances less than 5 ohms?

Yes	No
GO to A7.	REPAIR the open circuit. CLEAR the DTCs. REPEAT the self-test.

A7 CHECK FOR CORRECT PCM OPERATION

Disconnect all the PCM connectors.
Visually inspect for:
- pushed out pins
- corrosion
Connect all the PCM connectors and make sure they seat correctly.
Carry out the PCM self-test and verify the concern is still present.

Is the concern still present?

Yes	No
INSTALL a new PCM. REFER to FLASH ELECTRICALLY ERASABLE PROGRAMMABLE READ ONLY MEMORY (EEPROM) .	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
