XA2 LEDs (1) XA2 module (2) Green power LED (3) Yellow or red status LED | |
XA2 modules (1) can provide specific status and error detections. There are two indicators on the XA2 module. Green power LED (3) indicates when the module has power. Status LED (2) indicates the status of the module. The Status LED can be red or yellow.
When Status LED (2) is flashing yellow, the module detects normal status. If the Status LED is flashing red, the module detects an error. When the module detects an error, the nature of the flashing LED gives an indicator of the type of error that exists.
| XA2 STATUS LEDs | ||
|---|---|---|
| RED FLASH SEQUENCE | YELLOW FLASH SEQUENCE | STATUS |
| [] ... []... [] ... [] | NORMAL (SLOW CONTINUOUS) | |
| [] | [] | MD3 ERROR |
| [] [] | [] | MD3 ERROR |
| [] [] [] | [] | CAN ERROR |
| [] [] [] | [] [] | ADDRESS ERROR |
| [] [] [] [] | [] | MEMORY ERROR |
| [] [] [] [] [] [] [] [] | FATAL ERROR (CONTINUOUS) | |
Status LED (2) is interpreted by the flashing color and time sequence as follows:
- Flashing yellow in a continuous slow pattern indicates normal (no errors).
- One red flash and one yellow flash indicates a display controlled error.
- Two red flashes and one yellow flash indicates a display controlled error code.
- Three red flashes and one yellow flash indicates a CAN error.
- Three red flashes and two yellow flashes indicates an address error.
- Four red flashes indicates a FRAM error.
- Continuous red flashing indicates a fatal error.
When an error is detected by one of XA2 modules (1), and error message automatically appears on the MD3 display. The MD3 will also display conditional messages that alert the operator to important machine conditions.
The internal diagnostics of the display may be used in order to retrieve more information about XA2 modules (1).
The following tables contain information about the different possible failure modes that could occur for each module subsystem. In most cases when an error is detected, a message will be presented on the MD3 display together with an error code on the module.
WDS ECM/Display Failure Modes for CAN Interface
| Code | Failure Mode | Cause |
|---|---|---|
| 200 | J1939 error | J1939 error detected at parameter input channel (PIN). (The device sending a CAN message has a malfunction). |
| 201 | J1939 not available | Parameter (PIN) not available in J1939 parameter group (PGIN). (A device has not come online in the CAN network). |
| 202 | Time out | Time out detected on parameter group input (PGIN) or generic frame input (GFIN). (CAN took too long to work). |
| 203 | No contact | No contact with expansion module. (Applies to all modules). |
| 204 | Multiple address | Two or more IQAN modules with same address detected. |
| 209 | CAN bus error | CAN bus does not work. |
| 210 | Address error | Invalid address tag on master module. |
WDS ECM/Display Failure Modes for Reference Voltage (VREF)
| Code | Failure Mode | Cause |
|---|---|---|
| 205 | VREF error | VREF error detected on IQAN module. (each module has a voltage return for solenoids and power supplies, this error code indicates an error with the modules circuit). |
WDS ECM/Display Failure Modes for Voltage In (VIN)
| Code | Failure Mode | Cause |
|---|---|---|
| 192 | Low error | Value below low error level on input channel. (level set in software). |
| 193 | High error | Value over high error level on input channel. (level set in software). |
| 208 | Pin conflict | Invalid channel type connected to module pin. |
| 212 | Input error | Error detected on input channel (used by AAC, DDC, and ADC channels). |
WDS ECM/Display Failure Modes for Digital In(DIN)
| Code | Failure Mode | Cause |
|---|---|---|
| 208 | Pin conflict | Invalid channel type connected to module pin. |
| 212 | Input error | Error detected on input channel (used by AAC, DDC, and ADC channels). |
| 213 | Diff. check error | Input channels not equal (used by AAC, DDC, and ADC channels). |
WDS ECM Failure Modes in Current Output Mode
| Code | Failure Mode | Cause |
|---|---|---|
| 135 | Saturated | Not able to output commanded current. Current is 50 to 100 percent of commanded. |
| 194 | Overload | Output is overloaded. |
| 195 | Open load | Output is disconnected. Current is less than 50 percent of commanded. |
| 208 | Pin conflict | Invalid channel type connected to module pin. |
| Code | Failure Mode | Cause |
|---|---|---|
| 128 | High temp. | Module internal temperature. (WDS ECMs). |
| 129 | Low supply voltage | Module supply voltage. (WDS ECMs). |
| 130 | High supply voltage | Module supply voltage. (WDS ECMs). |
| 131 | Date and time not set | Applies to Display ECM only. |

MD3 Display Error, Alarm, and Warning Messages (4) Display module (5) Error message (6) "F2" key | |
MD3 display module (4) can display error, alarm, and warning messages (5) to the operator on the display.
The user must acknowledge all errors with the "F2" key (6). If multiple errors are present, each error must be dismissed individually with the "F2" key.
MD3 display module (4) can display various alarm, error, and warning messages. Some examples are as follows:
- Low water
- Sensor failure
- Tank lift mode disabled
- High hydraulic temperature
- Low hydraulic oil
- Oil filter differential pressure
- Low water pressure
- Tank not empty (lift mode)
- No contact (CAN)
- Low voltage
- High voltage
- VREF error
The color of the header in the box indicates the severity of the alarm or error. Boxes with a red header indicate that the error requires immediate attention. These errors are most severe. The header will indicate "Error".

Conditional Error Message (7) Type of message (8) Associated component (9) Message text (10) Value | |
The conditional error messages are comprised of the following segments:
- Type of conditional message (7)
- Associated component or module (8)
- Message text (9)
- Value (if applicable) (10)

|
Alarm Message (11) "Alarm" Header | |
Boxes with an orange header are an alarm for moderately severe errors that may require immediate attention. The header will indicate "Alarm" (11).

Warning Display (12) Warning | |
Warnings (12) are displayed directly over the current screen display in red type font. Warnings may include a message of appropriate action. Severity of the condition is variable, from a low water tank level, to an overheat condition requiring immediate engine shutdown.
