Remote Convenience: Overview Ford Explorer IV

Normal Operation

The universal transmitter is integral to the overhead console. The universal transmitter can be programmed to operate up to 3 garage doors, entry gates, security systems, and home or office lighting. Voltage is supplied to the universal transmitter through circuit CLN01 (GN/VT) and grounded on circuit GD133 (BK).

Possible Causes

1. Circuit CLN01 (GN/VT) open
2. Circuit GD133 (BK) open
3. Receiver unit
4. Universal transmitter

Scheme 1

Scheme 2

1. A1 CHECK THE OPERATION OF THE INTERIOR LAMPS Open the LH visor mirror. Does the visor illumination operate correctly? YES : Go to A2 . NO : REFER to «INTERIOR LIGHTING»(ref-270938) to continue diagnosis of the interior lamps.
2. A2 CHECK THE UNIVERSAL TRANSMITTER Press any of the buttons on the universal transmitter. Does the universal transmitter LED illuminate? YES : Go to A3 . NO : Go to A4 .
3. A3 PROGRAM A HAND-HELD TRANSMITTER INTO THE UNIVERSAL TRANSMITTER Program the universal transmitter. Refer to «Universal Transmitter Programming»(ref-270968-S03961746022007110700000) . Does the universal transmitter program successfully? YES : The universal transmitter is OK. VERIFY the receiver operates correctly. NO : INSTALL a new universal transmitter. TEST the system for normal operation.
4. A4 CHECK CIRCUIT CLN01 (GN/VT) FOR AN OPEN Key in OFF position. Disconnect: Universal Transmitter C928 Key in ON position. Measure the voltage between the universal transmitter C928-2, circuit CLN01 (GN/VT), harness side and ground. Is the voltage greater than 10 volts? YES : Go to A5 . NO : REPAIR the circuit. TEST the system for normal operation.
5. A5 CHECK CIRCUIT GD133 (BK) FOR AN OPEN Key in OFF position. Measure the resistance between the universal transmitter C928-1, circuit GD133 (BK), harness side and ground. Is the resistance less than 5 ohms? YES : INSTALL a new universal transmitter. TEST the system for normal operation. NO : REPAIR the circuit. TEST the system for normal operation.
