Pinpoint Test G: The Individual Component Illumination Is Inoperative
WARNING: This page is about a different car, the 2008 Mercury Sable, 2008 Ford Taurus X, and 2008 Ford Taurus. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
- G1 CHECK THE VOLTAGE TO THE SINGLE ILLUMINATION SOURCE
- Key in OFF position.
- Disconnect: Inoperative Illumination Source
- Place the headlamp switch to the PARKING LAMPS ON position.
- Rotate the instrument panel dimmer switch to the full illumination position.
- Measure the voltage between the inoperative illumination source, harness side and ground as follows:
Component Connector-Pin Circuit Adjustable pedal switch (if equipped) C2235-5 VLN04 (VT/GY) Auxiliary climate control switches (if equipped) C990-6 VLN04 (VT/GY) Clock (if equipped) C2016-2 VLN04 (VT/GY) Decklid release switch (if equipped) C2269-5 VLN04 (VT/GY) Floor shifter C3245-3 VLN04 (VT/GY) Hazard/parking aid/roll stability control/power liftgate switch C2114-7 VLN04 (VT/GY) Headlamp switch C205-2 VLN04 (VT/GY) LR heated seat switch (if equipped) C3340-5 VLN04 (VT/GY) RR heated seat switch (if equipped) C3341-5 VLN04 (VT/GY) - Are the voltages greater than 10 volts?
- YES : TURN the headlamps off. Go to G2.
- NO : REPAIR the circuit. TEST the system for normal operation.
- G2 CHECK THE GROUND CIRCUIT TO THE SINGLE ILLUMINATION SOURCE FOR AN OPEN
- Key in OFF position.
- Measure the resistance between the inoperative illumination source, harness side and ground according to the following table:
Illumination Source Connector-Pin Circuit Adjustable pedal switch (if equipped) C2235-4 GD111 (BK/BU) Auxiliary climate control switches (if equipped) C990-5 GD147 (BK/VT) Clock (if equipped) C2016-4 GD111 (BK/BU) Decklid release switch (if equipped) C2269-4 GD111 (BK/BU) Floor shifter C3245-4 GD111 (BK/BU) Hazard/parking aid/roll stability control/power liftgate switch C2114-4 GD111 (BK/BU) Headlamp switch C205-1 GD111 (BK/BU) LR heated seat switch (if equipped) C3340-1 GD133 (BK) RR heated seat switch (if equipped) C3341-1 GD133 (BK) - Is the resistance less than 5 ohms?
- YES : INSTALL a new component in question. TEST the system for normal operation.
- NO : REPAIR the circuit. TEST the system for normal operation.
