U1417

U1417-IMPLAUSIBLE LEFT WHEEL DISTANCE SIGNAL RECEIVED

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

Theory of Operation

The Powertrain Control Module (PCM) receives wheel speed and wheel distance CAN bus messages from the Anti-lock Brake (ABS) module.

- When Monitored:
With the ignition on, the battery voltage between 9 and 16 Volts and engine run time greater than three seconds.

- Set Condition:
The Powertrain Control Module (PCM) either doesn't receive a bus message or receives an implausible bus message from the Anti-Lock Brake Module.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure.

1. ACTIVE DTC
1. Ignition on, engine not running.
2. With the scan tool, select View DTCs.

Is the U1417-IMPLAUSIBLE LEFT WHEEL DISTANCE SIGNAL RECEIVED Active at this time?

Yes

- Go To 2

No

- Perform the INTERMITTENT CONDITION diagnostic procedure. Intermittent Condition Test.

2. ABS MODULE IS ACTIVE ON THE CAN C BUS
1. With the scan tool, select ECU View.
2. Verify that the ABS Module is active on the bus.

Is the ABS Module active on the bus?

Yes

- Go To 3

No
