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.
