WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

E1 CHECK FOR HIGH VOLTAGE DIAGNOSTIC TROUBLE CODES (DTCS) SET IN OTHER MODULES

Ignition ON.

Using a diagnostic scan tool, retrieve and record all Continuous Memory Diagnostic Trouble Codes (CMDTCs).

Is DTC B1317, B1318, B1676, U3003:16 or U3003:17 present in one or more modules AND are any charging system Diagnostic Trouble Codes (DTCs) present in the PCM?

Yes	DIAGNOSE the PCM Diagnostic Trouble Codes (DTCs). Refer to: Electronic Engine Controls - 6.2L V8 . Refer to: Electronic Engine Controls - 6.8L Triton-30V - V10 . Refer to: Electronic Engine Controls - 6.7L Power Stroke Diesel .

GO to E2

E2 CHECK THE BATTERY VOLTAGE

Turn off all interior lights, exterior lights and accessories.

NOTE: Do not allow the engine speed to increase above 2, 000 RPM while performing this step or the generator may self-excite and result in default charging system output voltage. If engine speed increases above 2, 000 RPM, turn the vehicle off and restart the engine before performing this step.

Start and run the engine at approximately 1, 500 RPM for 3 minutes while monitoring the battery voltage.

Is the battery voltage between 13 and 15.2 volts ?

Yes

GO to E3

No	DIAGNOSE the overcharging condition. Refer to: Charging System - 6.2L V8/6.8L Triton-30V - V10 . Refer to: Charging System - 6.7L Power Stroke Diesel .

E3 RECHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U3003:17

Turn the engine off.

Ignition ON.

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

Clear the ABS module Diagnostic Trouble Codes (DTCs).

Ignition OFF.

Ignition ON.

Repeat the ABS module self-test.

Is DTC U3003:17 still present?

Yes

GO to E4

No	The system is operating normally at this time. The DTC may have been set previously during battery charging or while jump starting the vehicle.

E4 VERIFY ALL WIRING CONNECTIONS
- Ignition OFF.
- Disconnect ABS module C135 .
- Disconnect all in-line electrical connectors between the ABS module and the BJB.
- Using a good light source, inspect all disconnected electrical connectors for the following:
  - corrosion - install new connector or terminal and clean the module pins
  - damaged or bent pins - install new terminals or pins
  - pushed-out pins - install new pins as necessary
  - spread terminals - install new terminals as necessary
Is the connector free of corrosion, damaged pins, bent pins, pushed-out pins and spread terminals?

Yes GO to E5

No REPAIR the connector or terminals. Refer to Connector Repair Procedures for schematic and connector information.

E5 CHECK FOR CORRECT ABS (ANTI-LOCK BRAKE SYSTEM) MODULE OPERATION

Connect all in-line electrical connectors between the ABS module and the BJB. Make sure they seat and latch correctly.

Connect ABS module C135 . Make sure it seats and latches correctly.

Operate the system and determine if 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 the TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new ABS module. Refer to: Anti-Lock Brake System (ABS) Module .

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