Pinpoint Tests J: ABS Module Communication Concern With SASM

J1: CHECK THE COMMUNICATION NETWORK

Ignition ON, engine OFF.
Press the Read Vehicle Information button to view the results of the modules communicating on the network.

Retrieve the continuous memory DTCs.

Yes	No
RETRIEVE and RECORD all SASM DTCs. REFER to the SASM DTC Chart. If there are no DTCs in the SASM, Go to J2.	DIAGNOSE the SASM does not communicate with the diagnostic scan tool. REFER to the Module Communications Network article.

J2: CHECK THE ABS DTCS

Carry out the ABS self-test.

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 J3.	The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.

J3: CHECK FOR DTC U3003:16 AND U3003:17

Review the recorded DTCs 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 .	Go to J5.

J4: RETRIEVE THE DTCS FROM THE SCCM SELF-TEST

Carry out the SCCM self-test.

Are any DTCs present?

Yes	No
DIAGNOSE the SCCM DTCs. REFER to the Steering Wheel and Column Electrical Components article.	Go to J6.

J5: RETRIEVE THE DTCS FROM THE SASM SELF-TEST

Carry out the SASM self-test.

Are any DTCs present?

Yes	No
DIAGNOSE the SASM DTCs. REFER to the SASM DTC Chart in this article.	Go to J6.

J6: 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.

Operate the system and determine if the observable symptom is still present.

Is the observable symptom still present?

Yes	No
Go to J7.	The system is operating correctly at this time. The concern may have been due to incorrect parts replacement procedures or incorrect module configuration.

J7: CHECK FOR COMMUNICATION DTCS IN OTHER MODULES

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

Is DTC U0126:xx or U0428:xx set in 1 or more modules in addition to the ABS module?

Yes	No
Go to J8.	Go to J9.

J8: VERIFY SASM OPERATION

Ignition OFF.
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
Operate the system and verify the concern is still present.

Is the concern still present?

Yes	No
INSTALL a new SASM. CHECK OASIS for any service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new SASM - clockspring assembly. REFER to the Supplemental Restraints System article. The SASM is part of the clockspring and the 2 components are serviced as an assembly.	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.

J9: VERIFY ABS MODULE OPERATION

Ignition OFF.
ABS Module connector disconnected. (C155)
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
ABS Module connector connected. (C155) Make sure the connector seats and latches correctly.
Operate the system and verify the concern is still present.

Is the concern still present?

Yes	No
INSTALL a new ABS module. CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW the TSB instructions.
