MID 122 - CID 1251 - FMI 03

SMCS - 1406-038

Conditions Which Generate This Code:

The Product Link module tracks the machine operating hours for reporting to the office. The Alternator R-Terminal signal is used to detect when the machine is operating. If the input continually receives a voltage signal that is above normal, then machine operation cannot be detected. If the input continually receives a voltage signal that is above normal, the reported Service Meter Hours (SMU) would be inaccurate.

Test Step 1. CHECK THE R-TERMINAL CABLING FOR SHORT TO BATTERY.

A. Disconnect the Product Link cable (P1) from the Product Link module.

B. Measure the resistance from the Alternator R-terminal input J1-4 (403MC9-GN-18 to battery (J1-1).

Expected Result:

The resistance should be greater than 5000 ohms.

Results:

• OK - The Product Link harness is likely correct. Proceed to Test Step 2.

• NOT OK - The Product Link cable has a probable short to battery. Repair: Repair the cable and verify that the fault has been removed.

STOP

Test Step 2. CHECK THE PRODUCT LINK HARNESS FOR A SHORT TO A VOLTAGE SOURCE.

A. Disconnect the Product Link cable (P1) from the Product Link module.

B. Start the engine.

C. Measure the Alternator R-Terminal input (J1-4) to verify that there is an 11 VDC to 32 VDC square-wave from 0 kHz to 2 kHz. Also, a steady DC voltage equivalent to the battery should be present.

Expected Result:

The Alternator R-Terminal input does not measure at a steady DC voltage equivalent to the battery voltage.

Results:

• OK - The signal is an 11 VDC to 32 VDC square-wave from 0kHz to 2 kHz or a steady DC voltage equivalent to the battery present. The Product Link harness is likely not faulty. Proceed to Test Step 3.

• NOT OK - The Product Link cable has a possible short to a DC voltage source other than battery voltage.

Repair: Repair the cable and verify that the fault has been removed.

STOP

Test Step

3. CHECK THE MACHINE ALTERNATOR.

A. Disconnect the Product Link machine cable from the alternator.

B. Start the engine.

C. Measure the Alternator R-Terminal to verify that there is 11 VDC to 32 VDC square-wave from 0 kHz to 2 kHz. There should not be a steady DC voltage equivalent to the battery present.

Expected Result:

The alternator R-Terminal should be an 11 VDC to 32 VDC square-wave from 0 kHz to 2 kHz.

Results:

• OK - The alternator R-Terminal is an 11 VDC to 32 VDC square-wave from 0 kHz to 2 kHz. Proceed to Test Step 4.

• NOT OK - The alternator R-Terminal is not an 11 VDC to 32 VDC square-wave from 0 kHz to 2 kHz.

Repair: Repair the alternator or replace the alternator.

Communication with the satellite will not occur when power to the Product Link is below 10.5 VDC. The Product Link will still communicate with Caterpillar Electronic Technician (Cat ET) when power to the module is down to 9 VDC. A diagnostic code of "CID 168 FMI 01" will occur when the system voltage drops below 11 VDC. A diagnostic code of "CID 254 FMI 04" will occur when the system voltage drops below 9 VDC.

(1) For troubleshooting, see the procedure with the same CID FMI.

Note: A machine ECM will self-erase a diagnostic if the diagnostic does not reappear after 100 operating hours. When this event happens, the event history screen in the EquipmentManager

application will show a code that occurred 100 hours in the past that no longer shows up in Cat ET because the diagnostic has not reoccurred.

Event Code List

SMCS - 7569

i05662643

Event codes alert the operator or the technician that an abnormal operating condition exists in one of the machine systems.

When an Electronic Control Module (ECM) activates an event code, the operator or the technician will be alerted by the Messenger. Most active events will be logged by the ECM. Some events are active only. Active only events are not logged. The events that are active and the events that are logged can be viewed with the following equipment:

• Messenger

• Caterpillar Electronic Technician (Cat ET)

Warning Levels

The ECM will assign a warning level to an active event code. Event codes are one of three levels. The level is according to the severity of the abnormal condition. Each warning level requires a specific response from the operator. The warning levels and the required operator response are listed below.

Warning Level 1

Warning level 1 alerts the operator that a machine system requires attention. The operator should check that the involved system condition or the operator should perform maintenance on the involved system at the earliest possible time.

Warning Level 2

Warning level 2 requires changing the operation of the machine or performing a maintenance procedure. Failure to correct a problem that caused this warning may result in damage to the components involved in the system.

Warning Level 2S

Warning level 2S requires an immediate change in machine operation in order to avoid possible damage to the system.

Warning Level 3

Warning level 3 requires an immediate safe shutdown of the machine in order to avoid damage to the machine or injury to personnel around the machine. The problem that caused the event must be corrected before machine operation can resume.

Indications and System Response

Caterpillar Electronic Technician (Cat ET) Service Tool

When an abnormal operating condition occurs, the status screen on the Cat ET indicates that there is an active event.

Event codes are displayed on Cat ET in the following format:

EXXXX Description of the code

The "E" means that the code is an event code. The "XXXX" is a numeric identifier. The numeric identifier is followed by a description of the code.

Active event codes are listed in ascending numerical order. The code with the lowest number is listed first. The active event code is removed from the list when the condition is no longer present.

Logged Event Codes

Some event codes are logged in the ECM memory. Some event codes are active only. The logged event codes are listed in chronological order. The most recent code is listed first.

A logged code is cleared from memory when one of the following conditions occur:

• The service technician manually clears the code.

• The code does not reoccur for 1000 hours.

• A new code is logged and there are already ten logged codes in memory. In this case, the oldest logged code is cleared.

Note: Always clear logged event codes after investigating and correcting the problem which generated the code.
