Pinpoint Test D: DTC U0167:00
Normal Operation
- DTC U0167:00 (Lost Communication With Vehicle Immobilizer Control Module: No Sub Type Information) - sets in the Body Control Module (BCM) if data messages received from the Remote Function Actuator (RFA) module are missing. For a complete list of all network messages, refer to Module Communications Network Testing and Inspection.
This pinpoint test is intended to diagnose the following:
- Communication network concern
- RFA module
- BCM
PINPOINT TEST D: DTC U0167:00
-------------------------------------------------
D1 VERIFY THE CUSTOMER CONCERN
- Ignition ON.
- Verify that there is an observable symptom present.
- Is an observable symptom present?
Yes
GO to D2.
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.
-------------------------------------------------
D2 CHECK THE COMMUNICATION NETWORK
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: Network Test.
- Carry out the network test.
- Does the RFA module pass the network test?
Yes
GO to D3.
No
REFER to Module Communications Network Testing and Inspection, The Remote Function Actuator (RFA) Module Does Not Respond To The Scan Tool.
-------------------------------------------------
D3 RETRIEVE THE RECORDED DTCs FROM THE BCM SELF-TEST
- Check for recorded BCM DTCs from the self-test.
- Is DTC U3003:16 or DTC U3003:17 recorded?
Yes
For DTC U3003:16, GO to Pinpoint Test F. For DTC U3003:17, GO to Pinpoint Test G. Pinpoint Test F: DTC U3003:16 Pinpoint Test G: DTC U3003:17
No
GO to D4.
-------------------------------------------------
D4 CHECK FOR DTCs U3003:16 AND U3003:17 FROM THE RFA MODULE SELF-TEST
- Retrieve the continuous memory DTCs from the RFA module.
- Is DTC U3003:16 or U3003:17 recorded?
Yes
For DTC U3003:16, GO to Pinpoint Test O Pinpoint Test O: DTC U3003:16. For DTC U3003:17, GO to Pinpoint Test P Pinpoint Test P: DTC U3003:17.
No
GO to D5.
-------------------------------------------------
D5 RECHECK THE BCM DTCs
NOTE: If new modules were installed prior to the DTC being set, the module configuration may be incorrectly set during Programmable Module Installation (PMI) or the PMI may not have been carried out.
- Clear the DTCs. Repeat the BCM self-test.
- Is DTC U0167:00 still present?
Yes
INSTALL a new RFA module. REFER to Remote Function Actuator (RFA) Module Service and Repair. CLEAR the DTCs. REPEAT the BCM self-test. If the concern is still present after the repair, INSTALL a new BCM. REFER to Body Control Module (BCM) Body Control Module (BCM). TEST the system for normal operation.
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.
