Pinpoint Test A: The Universal Transmitter is Inoperative
Refer to appropriate WIRING DIAGRAM ARTICLE, Interior Lamps for schematic and connector information.
Normal Operation
The universal transmitter receives voltage on circuit CLN09 (YE/GN) and is grounded through circuit GD133 (BK).
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
- 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?
- A2 PROGRAM A HAND-HELD TRANSMITTER INTO A UNIVERSAL TRANSMITTER
- Program the universal transmitter. Refer to Universal Transmitter Programming .
- 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. REFER to INTERIOR TRIM AND ORNAMENTATION article, Headliner. TEST the system for normal operation.
- 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 : REPAIR the circuit. TEST the system for normal operation.
- A4 CHECK CIRCUIT GD133 (BK) FOR AN OPEN
- Key in OFF position.
- Measure the resistance between the LH vanity mirror lamp C907-2, circuit GD133 (BK), harness side and ground.
- Is the resistance less than 5 ohms?
- YES : INSTALL a new LH sun visor assembly. REFER to INTERIOR TRIM AND ORNAMENTATION article, Headliner. TEST the system for normal operation.
- NO : REPAIR the circuit. TEST the system for normal operation.
