Pinpoint Test S: DTCs U1000:00, DTC U3000:49

Remote Function Actuator (RFA) Module

Pinpoint Tests

Pinpoint Test S: DTCs U1000:00, DTC U3000:49

Normal Operation

When a repetitive fault causing a circuit overload is detected on certain output circuits, the Remote Function Actuator (RFA) module disables the circuit by removing voltage or ground to the affected circuit. The circuit remains disabled until the fault is corrected and the DTCs are cleared, and then the self-test is repeated. When the on-demand self-test has been run after all faults have been corrected, any DTCs related to the fault are cleared.

- DTC U1000:00 (Solid State Driver Protection Active - Driver Disabled: No Sub Type Information) - a continuous DTC that sets when the RFA module has disabled a circuit due to a repetitive fault causing a circuit overload.
- DTC U3000:49 (Control Module: Internal Electronic Failure) - a continuous DTC that sets when one or more output functions are permanently disabled due to a repetitive circuit overload fault. DTC U3000:49 sets with DTC U1000:00. When DTC U3000:49 is present, the RFA module must be replaced after the fault condition has been corrected.

This pinpoint test is intended to diagnose the following:

- Output circuit short to ground or voltage
- RFA module



PINPOINT TEST S: DTCs U1000:00, DTC U3000:49

NOTICE: If DTC U3000:49 is present and the Remote Function Actuator (RFA) module is being replaced, the fault condition must be corrected first. Failure to correct the fault condition first may cause damage to the new RFA module, resulting in a repeat repair.

NOTE: The ignition must be OFF to carry out the RFA module self-test.

-------------------------------------------------
S1 REVIEW THE DTCs


- Review the DTCs from the RFA module self-test.
- Is only DTC U3000:49 present?

Yes
INSTALL a new RFA module. REFER to Remote Function Actuator (RFA) Module Remote Function Actuator (RFA) Module. TEST the system for normal operation.

No
CORRECT any DTCs present other than DTC U1000:00 (DTC U3000:49 may also be present). REFER to Diagnostic Trouble Code (DTC) Chart Diagnostic Trouble Code (DTC) Chart. After the repair, GO to S2.

-------------------------------------------------
S2 CARRY OUT THE RFA MODULE SELF-TEST


- Carry out the RFA module self-test.
- Is only DTC U3000:49 present?

Yes
INSTALL a new RFA module. REFER to Remote Function Actuator (RFA) Module Remote Function Actuator (RFA) Module. TEST the system for normal operation.

No
The system is operating correctly at this time. The concern was caused by a fault in one of the output circuits, which is no longer present.
