Pinpoint Test A : U0100:00
- A1 VERIFY SCAN TOOL COMMUNICATION WITH THE PCM (POWERTRAIN CONTROL MODULE)
- Connect the scan tool and check that a vehicle session can be established.
Can a vehicle session be established?
- Yes: GO to A2
- No:
To diagnose no communication with the PCM.
REFER to: Communications Network ( COMMUNICATIONS NETWORK ).
- A2 CHECK THE OCSM (OCCUPANT CLASSIFICATION SYSTEM MODULE) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)
- Ignition ON.
- Using a diagnostic scan tool, perform OCSM self-test.
- Using a diagnostic scan tool, clear OCSM Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Using a diagnostic scan tool, perform OCSM self-test.
Is DTC U0100:00 retrieved again?
- Yes: GO to A3
- No: The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.
- A3 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE PCM (POWERTRAIN CONTROL MODULE) KOEO (KEY ON, ENGINE OFF) SELF-TEST
- Check for recorded Diagnostic Trouble Codes (DTCs) from the PCM KOEO self-test.
Is DTC P0562 or P0563 recorded?
- Yes:
DIAGNOSE and REPAIR the PCM Diagnostic Trouble Codes (DTCs).
REFER to: Electronic Engine Controls ( ELECTRONIC ENGINE CONTROLS (2.0L Duratec-HE) .
REFER to: Electronic Engine Controls ( ELECTRONIC ENGINE CONTROLS (2.0L EcoBoost) .
- No: GO to A4
- A4 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE OCSM (OCCUPANT CLASSIFICATION SYSTEM MODULE) SELF-TEST
- Check for recorded Diagnostic Trouble Codes (DTCs) from the OCSM self-test.
Is DTC U3003:16 or U3003:17 recorded?
- Yes: REFER to: Pinpoint Test - Vehicles Built From: 11-June-2012, DTC: U3003:16 and U3003:17 .
- No: GO to A5
- A5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0100:00 SET IN OTHER MODULES
- Ignition ON.
- Using a diagnostic scan tool, perform self-test for all modules.
- Retrieve the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC U0100:00 set in the ABS module or in the IPC?
- 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 PCM.
