Pinpoint Test U : The Remote Start Feature Is Inoperative (If Equipped)

NOTE: This pinpoint test does not diagnose dealer installed remote start systems.

U1 CHECK THE REMOTE START FEATURE ENABLE/DISABLE SETTING
- Ignition ON.
- Using the steering wheel control switch, check the remote start feature setting in the IPC message center.
Is the remote start feature enabled?

Yes GO to U2

No ENABLE the remote start feature.

U2 CHECK THE PARK DETECT SWITCH INPUT
- Ignition ON.
- Verify the PRNDL displays correctly in the IPC. When the vehicle is in PARK, the P should be highlighted or displayed prominently.
Does the PRNDL display correctly?

Yes GO to U3

No DIAGNOSE the PRNDL. REFER to: Instrumentation, Message Center and Warning Chimes .

U3 CHECK FOR BCM (BODY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, perform the BCM self-test.
Are any BCM Diagnostic Trouble Codes (DTCs) present?

Yes REFER to BCM

No GO to U4

U4 CHECK FOR POWERTRAIN DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, perform the PCMKOEO and KOER self-tests.
Are any PCM Diagnostic Trouble Codes (DTCs) present?

Yes REFER to PCM

No GO to U5

U5 CHECK THE RKE (REMOTE KEYLESS ENTRY) FUNCTIONALITY

Ignition OFF.

Using the RKE function of the passive key, press the liftgate release button twice, the lock button and then the unlock button.

Do all the functions tested of the RKE transmitter operate (lock, unlock and liftgate latch release or power liftgate open)?

Yes

GO to U6

No	If all of the functions are inoperative, GO to Pinpoint Test R If an individual function is inoperative, GO to Pinpoint Test S

U6 CHECK THE WAKE-UP CIRCUIT FOR VOLTAGE AT THE PCM (POWERTRAIN CONTROL MODULE) USING THE BCM (BODY CONTROL MODULE) PID (PARAMETER IDENTIFICATION) (PCM) WAKE-UP OUTPUT CONTROL (PCM_WKUP_CTRL)

Disconnect: PCM C1915B.

Ignition ON.

Using a diagnostic scan tool, command the BCMPIDPCM_WKUP_CTRL on.

Measure:

Positive Lead	Measurement / Action	Negative Lead
Refer to C1915B-85	Courtesy of FORD MOTOR COMPANY	Ground

Is the voltage greater than 11 volts?

Yes

GO to U8

GO to U7

U7 CHECK THE WAKE-UP CIRCUIT FOR AN OPEN

Ignition OFF.

Disconnect: BCM C2280F.

Measure:

Positive Lead	Measurement / Action	Negative Lead
Refer to C1915B-85	Courtesy of FORD MOTOR COMPANY	Refer to C2280F-18

Is the resistance less than 3 ohms?

Yes

GO to U9

No	REPAIR the circuit.

U8 VERIFY THE REMOTE START FUNCTION IS INOPERATIVE

Ignition OFF.

Connect: PCM C1915B.

Close all the doors, the hood and the liftgate.

Using the key:
- Press the door lock button.
- Press the remote start button twice.

Does the vehicle remotely start?

Yes	The system is operating correctly. INFORM the customer of the correct vehicle remote start operation.

No	REPLACE the suspect key. PROGRAM the new key. For an IKT, REFER to: GENERAL PROCEDURES For a passive key, REFER to: GENERAL PROCEDURES

U9 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION

Disconnect and inspect all the BCM connectors.

Repair:
- corrosion (install new connectors 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 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 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, Refer to BCM GUIDED ROUTINE TESTING

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.
