Drivetrain Control Module (DTCM)

U0415-IMPLAUSIBLE DATA RECEIVED FROM ABS

For a complete wiring diagram, refer to the Wiring Information.

- When Monitored:
With the ignition on for Four seconds, no CAN BUS circuit error condition present, no lost communication with ABS condition present, and no system undervoltage or overvoltage condition present.

- Set Condition:
The Drive Train Control Module (DTCM) is receiving implausible data for vehicle speed, wheel speeds, brake switch status, longitudinal acceleration, yaw rate, or lateral acceleration from the ABS controller.





1. CHECK FOR DTC U0401-IMPLAUSIBLE DATA RECEIVED FROM TCM

NOTE: This DTC must be active for the results of this test to be valid.

1. Turn the ignition on.
2. With the scan tool, record and erase DTCs.
3. Cycle the ignition switch from off to on.
4. With the scan tool, read DTCs.

Does the scan tool display: U0401-IMPLAUSIBLE DATA RECEIVED FROM TCM?

Yes

- Go To 2

No

- Go To 4

2. CHECK IF TIPM CAN BUS DTCs ARE PRESENT
1. With the scan tool, read TIPM DTCs.

Are there any TIPM CAN BUS DTC's present?

Yes

- Perform the appropriate diagnostic procedure. Testing and Inspection.

No

- Go To 3

3. ABS DTCs PRESENT
1. Ignition on, engine not running.
2. With the scan tool, read DTCs in the Antilock Brake Controller.

Are there any DTCs present?

Yes

- Perform the appropriate diagnostic procedure. Testing and Inspection.

No

- Replace the Drive Train Control Module (DTCM).
- Perform DTCM VERIFICATION TEST. DTCM Verification Test.

4. INTERMITTENT WIRING HARNESS AND CONNECTORS
1. The conditions necessary to set this DTC are not present at this time.
2. Using the wiring diagram/schematic as a guide, inspect the wiring harness and connectors.
3. Wiggle test the wiring harness and connectors while monitoring the scan tool data relative to this circuit.
4. Look for the data to change or for the DTC to reset during the wiggle test.
5. While monitoring the scan tool data relative to this circuit, move the selector switch to each position several times (if equipped).

Were there any problems found?

Yes

- Repair as necessary.
- Perform DTCM VERIFICATION TEST. DTCM Verification Test.

No

- Test complete.
