Normal Operation and Fault Conditions

With the ignition ON, the CCM sends messages to the ABS module over the HS-CAN 2. If the ABS module does not receive these messages within a certain time frame, the ABS module sets a DTC. For information on the messages sent to the ABS module by the CCM, refer to the Network Message Chart.

PPT R ABS MODULE DTC FAULT TRIGGER CONDITIONS

DTC	Description	Fault Trigger Conditions
U0104:00	Lost Communication With Cruise Control Module: No Sub Type Information	Sets when the ABS module detects any of the following CCM messages are missing: collision mitigation by braking deceleration, collision mitigation by braking precharge, adaptive cruise control deceleration or adaptive cruise control precharge.
U0405:41	Invalid Data Received From Cruise Control Module: General Checksum Failure	This DTC sets if the collision mitigation by braking deceleration message checksum is invalid.
U0405:82	Invalid Data Received From Cruise Control Module: Alive/Sequence Counter Incorrect/Not Updated	This DTC sets if the collision mitigation by braking deceleration message rolling counter is invalid.
U0405:86	Invalid Data Received From Cruise Control Module: Signal Invalid	This DTC sets if the CCM is requesting an external apply of the electric parking brake and the vehicle is not in static mode.

R1: CHECK THE COMMUNICATION NETWORK

Ignition ON, engine OFF.
Using a diagnostic scan tool, carry out the Network Test.

Does the CCM pass the Network Test?

Yes	No
Go to R2.	For Transit, DIAGNOSE the scan tool does not communicate with the PCM. REFER to Module Communications Network (Hybrid/Energi) . For all others, DIAGNOSE the scan tool does not communicate with the CCM. REFER to Module Communications Network (Hybrid/Energi) .

R2: RECHECK FOR THE ABS MODULE DTCS

Clear the ABS DTCs.
Ignition OFF.
Ignition ON, engine OFF.
Carry out the ABS self-test.

Is DTC U0104:00, U0104:87, U0405:66, U0405:68, U0405:81, U0405:82 or U0405:83 retrieved again?

Yes	No
Go to R3.	The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.

R3: CHECK FOR DTC U3003:16 AND U3003:17

Review the results from the ABS module self-test.

Is DTC U3003:16 or U3003:17 present?

Yes	No
For DTC U3003:16, Go to PINPOINT TEST A . For DTC U3003:17, Go to PINPOINT TEST F .	For Transit, Go to R5. For all others, Go to R4.

R4: CHECK FOR DTCS IN THE CCM

Carry out the C-CM self-test.

Are any DTCs present?

Yes	No
DIAGNOSE the CCM DTC. REFER to the Cruise Control System (Hybrid/Energi) or Collision Warning System & Collision Avoidance System (Hybrid/Energi) .	Go to R7.

R5: CHECK FOR DTCS IN THE PCM

Carry out the PCM KOEO self-test.

Are any DTCs present?

Yes	No
DIAGNOSE the PCM DTC. REFER to the Electronic Engine Controls System - 2.0L Duratec - Hybrid (96kW/130PS) .	Go to R6.

R6: CHECK FOR OTHER CAUSES OF COMMUNICATION NETWORK CONCERN

NOTE: If new modules were installed prior to the DTC being set, the module configuration can be incorrectly set during the PMI or the PMI may not have been carried out.

Check the vehicle service history for recent service actions related to the CCM or the ABS module. If recent service history is found:
- Verify the correct replacement module was installed. HVBOM may be used to verify correct part fitment.
- Verify the configuration of replacement module was correct. Re-configure the module using as-built data if prior configuration is suspect.
- Verify the module was not obtained from a like vehicle and installed into customer vehicle. Return the swapped module to source vehicle and obtain new replacement module.
Operate the system and determine if the observable symptom is still present.

Is the observable symptom still present?

Yes	No
Go to R7.	The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.

R7: CHECK FOR LOST COMMUNICATION DTCS SET IN OTHER MODULES

Ignition ON, engine OFF.
Retrieve the continuous memory DTCs.

Is DTC U0104:xx or U0405:xx set in one or more modules in addition to the ABS module?

Yes	No
For Transit, Go to R8. For all others, Go to R9.	Go to R10.

R8: CHECK FOR CORRECT PCM OPERATION

Ignition OFF.
PCM_B connector disconnected. (C1915B)
PCM_E connector disconnected. (C1915E)
ABS Module connector disconnected. (C135)
Disconnect all in-line electrical connectors between the ABS module and the PCM.
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
Connect all in-line electrical connectors between the ABS module and the PCM. Make sure the connectors seat and latch correctly.
