Caterpillar Fault Codes List

Diagnostic codes alert the operator that a problem in the electronic system has been detected. Diagnostic codes are also used by the service technician to identify the nature of the problem. The technician must have access to a diagnostic tool to read diagnostic information.

The following Module Identifiers (MID) are used to identify the control modules that are associated
with engine operation:

• MID No. 036 is used to identify the engine Electronic Control Module (ECM)
• MID No. 094 is used to identify the Temperature Control Module (TCM)

Tables 1 and table 2 lists the diagnostic codes that apply to the engine ECM.
Table 3 lists the diagnostic codes that apply to the TCM for the engine cooling system.

Use Caterpillar Electronic Technician (ET) to determine the diagnostic codes that are active or
logged. Then refer to the appropriate troubleshooting procedure for more information.
Note: Do not confuse diagnostic codes with event codes. Event codes alert the operator that an
abnormal operating condition such as low oil pressure or high coolant temperature has been detected.
If an event code is active, refer to Troubleshooting, “Event Codes”.

Diagnostic information is transmitted over data links. This engine uses the following two types of data
links for communication. The data links are described below:

Cross-Reference Information for Diagnostic Codes that are Generated by the TCM Table 3 lists the diagnostic codes that apply to the TCM. MID No. 094 is used to identify the TCM.

Use Cat ET to determine the diagnostic codes that are active or logged. Then refer to the appropriate troubleshooting procedure for more information.

Note: Use Cat ET to clear diagnostic codes. Keyswitch power to the engine must be cycled to complete clearing of the codes from the TCM.

628-2 Program Memory : Erratic, Intermittent, or Incorrect During a self-test, the TCM has detected an internal memory fault. Replace the TCM.
630-2 Calibration Memory : Erratic, Intermittent, or Incorrect During a self-test, the TCM has detected a problem writing calibration data to memory. The TCM will continue to operate using calibration data that was stored previously. Replace the TCM during the next service interval.
2901-0 ECU Part Number : High – most severe (3) The internal temperature of the TCM has exceeded the operational range of the unit. The three-way valve is commanded to the fault position. If necessary, install heat shields or relocate the TCM.
2901-3 ECU Part Number : Voltage Above Normal The TCM has detected an electrical problem with the internal temperature sensor for the unit. The three-way valve is commanded to the fault position. Replace the TCM.
2901-4 ECU Part Number : Voltage Below Normal The TCM has detected an electrical problem with the internal temperature sensor for the unit. The TCM will continue to operate normally. Replace the TCM during the next service interval.
