Pinpoint Test I: Pcm (Powertrain Control Module) And TCM (Transmission Control Module) Communication Faults

I1 CHECK THE COMMUNICATION NETWORK
- Ignition ON.
- Using a diagnostic scan tool, carry out the Network Test.
Does the PCM pass the Network Test?
- Yes : GO to I2
- No : To diagnose the PCM does not communicate with the diagnostic scan tool,
  REFER to: COMMUNICATIONS NETWORK .
I2 CHECK THE ABS (ANTI-LOCK BRAKE SYSTEM) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)
- Using a diagnostic scan tool, carry out the ABS module self-test.
- Clear the ABS module Diagnostic Trouble Codes (DTCs).
- Ignition OFF.
- Ignition ON.
- Using a diagnostic scan tool, carry out the ABS module self-test.
- Retrieve and record the ABS module Diagnostic Trouble Codes (DTCs).
Are any of the Diagnostic Trouble Codes (DTCs) listed in the DTC Fault Trigger Conditions table retrieved again?
- Yes : GO to I3
- 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.
I3 REVIEW THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE ABS (ANTI-LOCK BRAKE SYSTEM) SELF-TEST
- Review the recorded Diagnostic Trouble Codes (DTCs) from the ABS self-test.
Is DTC U3003:16 or U3003:17 recorded?
- Yes : For DTC U3003:16, GO to PINPOINT TEST A
  For DTC U3003:17, GO to PINPOINT TEST F
- No : GO to I4
I4 RETRIEVE THE DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE PCM (POWERTRAIN CONTROL MODULE) SELF-TEST
- Using a diagnostic scan tool, carry out the PCM KOEO self-test.
Is DTC P0562 or P0563 present?
- Yes : DIAGNOSE the PCM Diagnostic Trouble Codes (DTCs).
  1.6L EcoBoost REFER to: ELECTRONIC ENGINE CONTROLS .
  
  2.5L Duratec REFER to: ELECTRONIC ENGINE CONTROLS .
- No : GO to I5
I5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) C0040:XX, U0100:XX, U0101:XX, U0401:XX OR U0402:00 SET IN OTHER MODULES
- Using a diagnostic scan tool, carry out the self-test for all modules.
- Retrieve the Continuous Memory Diagnostic Trouble Codes (CMDTCs) from all modules.
Is DTC C0040:xx, U0100:xx, U0101:xx, U0401:xx or U0402:00 set in 1 or more modules in addition to the ABS module?
- 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 PCM.
  1.6L EcoBoost REFER to: POWERTRAIN CONTROL MODULE (PCM) .
  
  2.5L Duratec REFER to: POWERTRAIN CONTROL MODULE (PCM) .
- No : 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 and HCU.
