BW1: CHECK THE COMMUNICATION NETWORK

Ignition ON, engine OFF.
Retrieve the continuous memory DTCs.
Do the IPMA and CCM pass the Network Test?

Yes	No
Go to BW2.	DIAGNOSE the no communication with the IPMA or CCM. REFER to the Module Communications Network article.

BW2: RECHECK THE ABS MODULE DTCS

Carry out the ABS self-test.

Record all ABS module DTCs.
Clear the ABS DTCs.
Ignition OFF.
Ignition ON, engine OFF.
Carry out the ABS self-test.
Are any of the DTCS listed in the Fault Setting Conditions Table retrieved again?

Yes	No
Go to BW3.	The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.

BW3: REVIEW THE RECORDED DTCS FROM THE ABS MODULE SELF-TEST

Check the DTCs recorded from the ABS module self-test.
Was DTC U3003:16 or U3003:17 recorded?

Yes	No
For DTC U3003:16, Go to PINPOINT TEST A . For DTC U3003:17, Go to PINPOINT TEST F .	Go to BW4.

BW4: CHECK FOR DTCS IN THE IPMA

Carry out the IPMA self-test.

Record all DTCs from the IPMA self-test.
Are any DTCs present in the IPMA?

Yes	No
DIAGNOSE all IPMA DTCs. REFER to the Lane Keeping System article.	Go to BW5.

BW5: CHECK FOR DTCS IN THE CCM

Carry out the C-CM self-test.

Record all DTCs from the CCM self-test.
Are any DTCs present in the CCM?

Yes	No
DIAGNOSE all CCM DTCs. REFER to the Cruise Control article.	Go to BW6.

BW6: 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 BW7.	The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.

BW7: CHECK FOR COMMUNICATION DTCS IN OTHER MODULES

Ignition ON, engine OFF.
Clear the ABS DTCs.
Retrieve the continuous memory DTCs.
Is DTC U0104:xx or U0433:xx set in 1 or more modules in addition to the ABS module?

Yes	No
Go to BW9.	Go to BW8.

BW8: VERIFY ABS MODULE OPERATION

Ignition OFF.
ABS Module connector disconnected. (C135)
conn_eauger_1479227526_acronymCCM#1acronym (Cruise Control Module) connector disconnected.
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
conn_eauger_1479227526_acronymCCM#1acronym (Cruise Control Module) connector connected. Make sure the connector seats and latches correctly.
