Garage Door Opener Transmitter: Pinpoint Tests
Universal Transmitter
Pinpoint Tests
Pinpoint Test A: The Universal Transmitter is Inoperative
Refer to Wiring Diagram Set 89, Interior Lamps for schematic and connector information. See: Diagrams/Electrical Diagrams/Diagrams By Number
Normal Operation
The universal transmitter receives voltage on circuit CLN09 (YE/GN) and ground on circuit GD133 (BK). When a button on the universal transmitter is
pressed, a radio frequency signal is sent to the receiver unit (if within the range of the receiver unit). The receiver unit will process the signal and
determines if it is the correct code. If the receiver unit determines it is the correct code (it may or may not be a rolling code, depending on the receiver
unit type), the receiver unit will operate the system, which may be a garage door opener, gate, home/office lighting or some type of a security system.
This pinpoint test is intended to diagnose the following:
-
Wiring, terminals or connectors
-
Universal transmitter
-
Receiver unit
PINPOINT TEST A: THE UNIVERSAL TRANSMITTER IS INOPERATIVE
NOTE: Failure to disconnect the battery when instructed will result in false resistance readings. Refer to Battery.
-------------------------------------------------
A1 CHECK THE UNIVERSAL TRANSMITTER
-
Press a button on the universal transmitter and check the illumination of the transmitter.
-
Does the transmitter LED illuminate when a button is pressed?
Yes
GO to A2.
No
GO to A3.

A2 PROGRAM A HAND-HELD TRANSMITTER TO THE UNIVERSAL TRANSMITTER
-
Program a hand-held transmitter to the universal transmitter. Refer to Universal Transmitter Programming See: Programming and Relearning.
-
Does the universal transmitter program successfully?
Yes
The universal transmitter is OK. VERIFY the receiver unit operates correctly.
No
INSTALL a new LH sun visor assembly. TEST the system for normal operation.
-------------------------------------------------
A3 CHECK CIRCUIT CLN09 (YE/GN) FOR VOLTAGE
-
Ignition OFF.
-
Disconnect: LH Vanity Mirror Lamp C907.
-
Ignition ON.
-
Measure the voltage between the LH vanity mirror lamp C907-1, circuit CLN09 (YE/GN), harness side and ground.
