Pinpoint Test H: The Ignition Switch (Push Button Start) Illumination Is Inoperative

Refer to Cluster And Panel Illumination for schematic and connector information.

Normal Operation and Fault Conditions

REFER to: Instrument Panel and Interior Switches Illumination - System Operation and Component Description .

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
BCM B1314:11	White Lighting (Reflective Controls) Illumination Output: Circuit Short To Ground	Sets when the BCM detects a short to ground from the backlighting illumination output.

Possible Sources

Wiring, terminals or connectors
Ignition switch (push button start)
BCM

H1 INSPECT ALL OTHER DIMMABLE ILLUMINATION SOURCES
- Ignition ON.
- Place the headlamp switch in the PARKING LAMPS ON position.
- While pressing the instrument panel dimmer switch up and down, observe all other dimmable illumination sources.
Do all other dimmable illumination sources increase and decrease in brightness?

Yes GO to H2

No GO to Pinpoint Test A

H2 CHECK FOR VOLTAGE TO THE IGNITION SWITCH (PUSH BUTTON START)

Disconnect Ignition Switch (push button start) C2195 .
NOTE: Leave the Ignition ON when disconnecting the Ignition Switch.

Using a diagnostic scan tool, carry out the BCM self-test.

Place the headlamp switch in the PARKING LAMPS ON position.

Press the instrument panel dimmer up switch until all other dimmable illumination is at its brightest intensity.

Is the voltage greater than 11 volts?

Yes

GO to H3

GO to H4

H3 CHECK THE IGNITION SWITCH (PUSH BUTTON START) GROUND CIRCUIT FOR AN OPEN

Measure:

Is the voltage greater than 11 volts?

Yes	INSTALL a new ignition switch (push button start). REFER to: Ignition Switch - Vehicles With: Keyless Entry and Push Button Start .

No	REPAIR the circuit

H4 CHECK THE BCM (BODY CONTROL MODULE) DIMMABLE VOLTAGE OUTPUT CIRCUIT FOR AN OPEN

Connect Ignition Switch (Push Button Start) C2195 .

Ignition OFF.

Disconnect Ignition Switch (Push Button Start) C2195 .

Disconnect BCM C2280B .

Measure:

Is the resistance less than 3 ohms?

Yes

GO to H5

No	REPAIR the circuit.

H5 CHECK THE BCM (BODY CONTROL MODULE) DIMMABLE VOLTAGE OUTPUT CIRCUIT FOR A SHORT TO GROUND

Measure:

Positive Lead	Measurement / Action	Negative Lead
C2195-5	Courtesy of FORD MOTOR COMPANY	Ground

Is the resistance greater than 10, 000 ohms?

Yes

GO to H6

No	REPAIR the circuit.

H6 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Disconnect and inspect all BCM and related in-line connectors.

Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary

Reconnect the BCM and related in-line connectors and all previously disconnected illumination system connectors. Make sure all connectors seat and latch correctly.

Operate the system to determine if the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new BCM. REFER to: Body Control Module (BCM) .

No	The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
