Pinpoint Test G : The Ignition Mode Indicator Is Inoperative

WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.

Starting System for schematic and connector information.

Normal Operation and Fault Conditions

REFER to: Steering Wheel and Column Electrical Components - System Operation and Component Description .

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Condition
BCM B1240:11	Start Button Mode Indicator: Circuit Short To Ground	Sets when the BCM detects a short to ground from the ignition mode status indicator circuit.
BCM B1240:15	Start Button Mode Indicator: Circuit Short To Battery Or Open	Sets when the BCM detects an open from the ignition mode status indicator circuit.

Possible Sources

Wiring, terminals or connectors
Push button ignition switch
BCM

NOTE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.

G1 CHECK FOR VOLTAGE TO THE IGNITION MODE INDICATOR

Start the engine.

Disconnect Push Button Ignition Switch C2195.

Measure:

Positive Lead	Measurement / Action	Negative Lead
Refer to C2195-2	Courtesy of FORD MOTOR COMPANY	Ground

Is the voltage greater than 11 volts?

Yes

GO to G4

GO to G2

G2 CHECK THE IGNITION MODE INDICATOR VOLTAGE CIRCUIT FOR A SHORT TO GROUND

Connect Push Button Ignition Switch C2195.

Ignition OFF.

Disconnect Push Button Ignition Switch C2195.

Disconnect BCM C2280D.

Measure:

Positive Lead	Measurement / Action	Negative Lead
Refer to C2195-2	Courtesy of FORD MOTOR COMPANY	Ground

Is the resistance greater than 10, 000 ohms?

Yes

GO to G3

No	REPAIR the circuit.

G3 CHECK THE IGNITION MODE INDICATOR VOLTAGE CIRCUIT FOR AN OPEN

Measure:

Positive Lead	Measurement / Action	Negative Lead
Refer to C2195-2	Courtesy of FORD MOTOR COMPANY	Refer to C2280D-20

Is the resistance less than 3 ohms?

Yes

GO to G5

No	REPAIR the circuit.

G4 CHECK THE IGNITION MODE INDICATOR GROUND CIRCUIT FOR AN OPEN

Measure:

Positive Lead	Measurement / Action	Negative Lead
Refer to C2195-2	Courtesy of FORD MOTOR COMPANY	Refer to C2195-3

Is the voltage greater than 11 volts?

Yes	INSTALL a new push button ignition switch. REFER to: Ignition Switch - Vehicles With: Push Button Start .

No	REPAIR the circuit.

G5 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Disconnect and inspect all BCM 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 connectors and all other previously disconnected connectors. Make sure they seat and latch correctly.

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

Is the concern still present?

Yes

CHECK On-Line Automotive Service Information System (OASIS) for any applicable Technical Service Bulletins (TSBs). If a Technical Service Bulletin (TSB) exists for this concern, DISCONTINUE this test and FOLLOW Technical Service Bulletin (TSB) instructions. If no Technical Service Bulletins (TSBs) 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.
