EXCEPT FOR M/T MODELS : Description

INFOID:0000000012198519

ECM receives vehicle speed signals from two different paths via CAN communication line: One is from the

ABS actuator and electric unit (control unit) via the combination unit and the other is from TCM.

NOTE:

• If DTC P0500 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.

• If DTC P0500 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607. Refer to

EC-

1054, "DTC Logic"

.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure

before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.
