Remote Convenience: Overview Mercury Milan I

Normal Operation

The universal transmitter receives voltage on circuit CLN09 (YE/GN) and is grounded through circuit GD139 (BK/YE).

Possible Causes

1. Fuse
2. Circuit CLN09 (YE/GN) open or short to ground
3. Circuit GD139 (BK/YE) open
4. Receiver unit
5. Universal transmitter

Scheme 1

Scheme 2

1. A1 CHECK THE UNIVERSAL TRANSMITTER Check the illumination of the universal transmitter by pressing one of the buttons. Does the red indicator on the universal transmitter illuminate? YES : Go to A2 . NO : Go to A3 .
2. A2 PROGRAM A HAND-HELD TRANSMITTER INTO A UNIVERSAL TRANSMITTER Program the universal transmitter. Refer to «Universal Transmitter Programming»(ref-271151-S21161713302007110800000) . Does the universal transmitter program successfully? YES : The universal transmitter is OK. VERIFY the receiver operates correctly. NO : INSTALL a new LH sun visor assembly. TEST the system for normal operation.
3. A3 CHECK CIRCUIT CLN09 (YE/GN) FOR VOLTAGE Disconnect: LH Vanity Mirror Lamp C907 Measure the voltage between the LH vanity mirror lamp C907-1, circuit CLN09 (YE/GN), harness side and ground. Is the voltage greater than 10 volts? YES : Go to A4 . NO : VERIFY the smart junction box (SJB) fuse 3 (15A) is OK. If OK, REPAIR the circuit. TEST the system for normal operation.
4. A4 CHECK CIRCUIT GD139 (BK/YE) FOR AN OPEN Key in OFF position. Measure the resistance between the LH vanity mirror lamp C907-2, circuit GD139 (BK/YE), harness side and ground. Is the resistance less than 5 ohms? YES : INSTALL a new LH sun visor assembly. TEST the system for normal operation. NO : REPAIR the circuit. TEST the system for normal operation.
