Pinpoint Test E : C1007:11, C1007:12, C1007:13, C1007:19

WARNING: This page is about a different car, the 2018 Lincoln Navigator. 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.

E1 CHECK THE RH (RIGHT-HAND) PRB (POWER RUNNING BOARD) MOTOR CONTROL CIRCUITS FOR A SHORT TO VOLTAGE

Ignition OFF.

Disconnect RH PRB motor C3186A .

Ignition ON.

Wait 10 seconds so any PRB movement commands are complete.

Are the resistances greater than 10, 000 ohms?

Yes

GO to E5

No	REPAIR the circuit.

E5 CHECK FOR CORRECT RBM (RUNNING BOARD CONTROL MODULE) OUTPUT

NOTE: Use a meter with a min-max feature or recording capabilities to obtain accurate measurements. The RBM disables the voltage output immediately if the PRB motor is not present

Connect RBM C3313A .

Ignition ON.

Make sure the PRB is set to AUTO in the vehicle message center.

Close all vehicle doors.

Connect the meter to the RH PRB motor electrical connector, harness side.

Set the meter to measure DC (direct current) voltage.

Set the meter range to greater than 15 volts.

Enable the min-max or recording feature on the meter.

NOTE: Make sure all test connections are made at the PRB motor before the RH door is opened.

Open any RH side door.

Measure:

Is the voltage greater than 10 volts?

Yes	REPLACE the RH PRB motor. REFER to: Power Running Board (PRB) .

GO to E6

E6 CHECK FOR CORRECT RBM (RUNNING BOARD CONTROL MODULE) OPERATION

Ignition OFF.

Disconnect All PRB system and related in-line connectors.

Check for:
- corrosion - install new connector or terminals and clean module pins
- damaged or bent pins - install new terminals or pins
- pushed-out pins - install new pins as necessary

Connect all PRB system and related in-line connectors and make sure they seat correctly.

Operate the system and verify the concern is still present.

Is the concern still present?

Yes	CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new RBM. REFER to:Power Running Board (PRB) .

No	The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
