Notes for Table 5

Note 1: This Diagnostic Trouble Code (DTC) occurs when the SmarTire

Trailer-Link

™

ECU has not received information from a tire sensor for 35

minutes. Possible causes are:
1. A tire has been replaced and a tire sensor is no longer in range of the

ECU and is therefore no longer being received. In this situation the

missing sensor must be replaced and the ECU reconfigured to add this

new sensor.

2. There is poor radio frequency signal quality between the sensor and the

ECU. Check the installation of the ECU and ensure it is not mounted

close to any metal objects and is in the correct location as described in

Section C, 4.0.

3. There is a malfunctioning sensor in one of the vehicle’s tires. In this

situation the malfunctioning sensor must be replaced and the ECU

reconfigured to add this new sensor.

Note 2: This Diagnostic Trouble Code (DTC) is generated when the

configuration information within the ECU has become corrupt. During this

DTC the ECU’s configuration is restored to the default factory setting. If this

DTC occurs all sensors registered in the ECU will be lost and all programmable

settings restored to factory settings. The ECU must be re-configured to

become operational again.

Note 3: This DTC is active if there are no tire sensors registered in the ECU.

This could be caused if the ECU was never configured or corruption of the

configuration information has occurred as in Note 3. To correct this situation,

tire sensors installed on the trailer must be learned into the ECU.

Note 4: This DTC is generated when the configuration information within the

ECU has become corrupt. The ECU has recovered from this by restoring

the configuration from a backup copy. Normally this DTC is self-corrected by

the ECU but the configuration should be analyzed to make sure all settings

are correct.

Note 5: This DTC is generated when the ECU has restarted due to a software

related failure. If this DTC occurs on a regular basis, the ECU should be

returned to Bendix for analysis.
