U0415-IMPLAUSIBLE DATA RECEIVED FROM ABS

For a complete wiring diagram Refer to Section 8W

Theory of Operation

The messages sent on the CAN bus are distinguished by an identifier (ID). Each CAN ID is defined to contain a certain number of bytes. The Transmission Control Module (TCM) verifies that it has received the proper number of bytes for each ID.

When Monitored:
Continuously with the ignition on, one valid CAN ID received at least once, and no U0002-CAN Bus Off Performance DTC present.
Set Condition:
When the TCM detects an incorrect CAN ID from the ABS control module.

Possible Causes

TIPM CAN BUS DTC'S PRESENT

ABS DTC'S PRESENT

ALL WHEEL DRIVE (AWD) CONTROL MODULE

Diagnostic Test

1.CHECK FOR TIPM CAN BUS DTCS

Are there any TIPM CAN BUS DTC's present?

Yes

(Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES - DIAGNOSIS AND TESTING) category and perform the appropriate symptom.
Perform AWD Control Module VERIFICATION TEST. (Refer to 3 - DIFFERENTIAL & DRIVELINE/ELECTRONICALLY CONTROLLED CLUTCH - STANDARD PROCEDURE).

2.CHECK IF ABS DTC'S ARE PRESENT

Are there any ABS DTC's present?

Yes

(Refer to 5 - BRAKES - DIAGNOSIS AND TESTING) category and perform the appropriate symptom.
Perform AWD Control Module VERIFICATION TEST. (Refer to 3 - DIFFERENTIAL & DRIVELINE/ELECTRONICALLY CONTROLLED CLUTCH - STANDARD PROCEDURE).

Using the schematics as a guide, check the AWD Control Module pins, terminals, and connectors for corrosion, damage, or terminal push out. Pay particular attention to all power and ground circuits. If no problems are found, replace the TCM per the Service Information. (Refer to 8 - ELECTRICAL/ELECTRONIC CONTROL MODULES/TRANSMISSION CONTROL MODULE - REMOVAL)
Perform AWD Control Module VERIFICATION TEST. (Refer to 3 - DIFFERENTIAL & DRIVELINE/ELECTRONICALLY CONTROLLED CLUTCH - STANDARD PROCEDURE).
