Tire Pressure Monitoring System (TPMS) — 2016 workshop reference 2588

U1A00:00

Normal Operation and Fault Conditions

With the ignition ON, the BCM and the RTM communicate using a LIN. If the RTM is unable to communicate with the BCM using this LIN, the RTM sets a DTC.

DTC Fault Trigger Conditions

DTC	Description	Fault Trigger Conditions
	U1A00:00 Private Communication Network: No Sub Type Information	This DTC sets in continuous memory if the RTM communication bus reset counter reaches zero. This is most likely due to a circuit failure in the LIN, an internal failure of the BCM or an internal failure of the RTM.

Description

Fault Trigger Conditions

U1A00:00 Private Communication

Network: No Sub Type Information

This DTC sets in continuous memory if the RTM communication bus reset counter reaches zero. This is most likely due to a circuit failure in the LIN, an internal failure of the BCM or an internal failure of the RTM.

Possible Sources

Wiring, terminals or connectors BCM RTM

PINPOINT TEST I : U1A00:00

NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.

I1 CHECK THE COMMUNICATION NETWORK

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

Do the RTM and the BCM pass the Network Test?

Yes	GO to I2
No	DIAGNOSE the RTM or BCM does not respond to the scan tool. REFER to: Communications Network (418-00 Module Communications Network, Diagnosis and Testing).

I2 CHECK FOR BCM (BODY CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)

Using a diagnostic scan tool, carry out the BCM self-test.

Are any Diagnostic Trouble Codes (DTCs) present in the BCM?

Yes	DIAGNOSE the Diagnostic Trouble Codes (DTCs). REFER to: Body Control Module (BCM) (419-10 Multifunction Electronic Modules, Diagnosis and Testing).
No	GO to I6

I3 CHECK THE RTM (RADIO TRANSCEIVER MODULE) BATTERY VOLTAGE INPUT FOR AN OPEN

Ignition OFF. Disconnect BCM C2280C. Disconnect RTM C4458. Measure:
