INSPECTION PROCEDURE

NOTICE:

Transmission/Transaxle/Testing and Inspection/Reading and Clearing Diagnostic Trouble Codes/U660E Automatic Transaxle

HINT

* Refer to inspection procedure for CAN communication system.

* If the CAN communication malfunctions, the TCM cannot receive the current data from the ECM. In this case, the freeze

frame data output from the TCM has not been updated, so the data will not be useful for the inspection. However, reading the

Data List as the first step in troubleshooting is effective to find malfunctions.

* The malfunction area can be checked using the Bus Check function on the Techstream See: Powertrain

Management/Computers and Control Systems/Information Bus/Testing and Inspection/Initial Inspection and Diagnostic

Overview/CAN Communication System/Diagnosis System.

1. CHECK ECU TERMINAL VOLTAGE (+B AND E1 TERMINALS)
