This diagnostic trouble code is triggered if the internal GPS signal is not recognized.
JDL 000964.13 (JDL 964.13)— Control Unit, Time / Date is Invalid
This diagnostic trouble code is triggered if no valid date or time is recognized.
JDL 001542.04 (JDL 1542.04)— Control Unit, Voltage Too Low
This diagnostic trouble code is triggered if power supply lies below 11.2 volts.
JDL 298872.31 — Machine Data Configuration Fault 5
This diagnostic trouble code is triggered if there is a fault in machine configuration.
JDL 298873.31 — Machine Data Configuration Fault 4
This diagnostic trouble code is triggered if there is a fault in machine configuration.
JDL 298874.31 — Machine Data Configuration Fault 3
This diagnostic trouble code is triggered if there is a fault in machine configuration.
JDL 298875.31 — Machine Data Configuration Fault 2
This diagnostic trouble code is triggered if there is a fault in machine configuration.
JDL 298876.31 — Machine Data Configuration Fault 1
This diagnostic trouble code is triggered if there is a fault in machine configuration.
JDL 298877.31 — Modem Fault
This diagnostic trouble code is triggered if there is an error in the integrated modem.
JDL 298878.31 — Line Busy
This diagnostic trouble code is triggered if no connection can be made. The JDL control unit automatically attempts to make a new connection.
JDL 298879.31 — Cellular Signal Weak or No Service

JDL 298881.18 — GPS Signal Lost (60 Seconds)
This diagnostic trouble code is triggered if no new signal is received within 60 seconds of the GPS signal being lost. Once a GPS signal is received, the diagnostic trouble code is deleted automatically.
JDL 298882.31 — GPS Signal Lost (30 Minutes)
This diagnostic trouble code is triggered if no new signal is received within 30 minutes of the GPS signal being lost. Once a GPS signal is received, the diagnostic trouble code is deleted automatically.
JDL 298883.31 — Vehicle CAN BUS, High Error Rate
The diagnostic trouble code is generated when the control unit receives too many incorrect CAN BUS messages or when it detects a general problem in the connection to the vehicle CAN BUS.
JDL 298884.31 — Vehicle CAN BUS, Very High Error Rate
The diagnostic trouble code is generated when the control unit receives too many incorrect CAN BUS messages or when it detects a general problem in the connection to the vehicle CAN BUS.
JDL 298885.31 — Control Unit, Memory Capacity Exceeded
This diagnostic trouble code is triggered if the internal memory of the JDL control unit is full. This indicates a problem in the connection to the JDLink server.
JDL 298886.31 — Control Unit, Power Level Exceeded
This diagnostic trouble code is triggered if the power level of the JDL control unit is overloaded. This indicates that the battery is flat.
JDL 298887.31 — Conflict Between Control Unit Configuration and Machine PIN
This diagnostic trouble code is triggered if the machine configuration of the JDL control unit does not match the configuration data from the vehicle CAN BUS.
JDL 299613.31 — Data Download Fault
This diagnostic trouble code is triggered if the connection is lost during data transfer. The diagnostic trouble code is deleted automatically as soon as a connection is made.
JDL 299614.31 — Data Upload Fault
This diagnostic trouble code is triggered if the connection is lost during data transfer. The diagnostic trouble code is deleted automatically as soon as a connection is made.
JDL 299615.31 — Cellular Bit Error Rate Too High
This diagnostic trouble code is triggered if the connection is lost due the error rate being too high.
JDL 299616.31 — Call Disconnected
This diagnostic trouble code is triggered if the call is disconnected. The diagnostic trouble code is deleted automatically as soon as a connection is made.
JDL 299617.31 — Data Exchange Fault
This diagnostic trouble code is triggered if the call is disconnected. The diagnostic trouble code is deleted automatically as soon as a connection is made.
