When each warning light blinks continuously, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in an ECU connected to this circuit may have occurred.
INSPECTION PROCEDURE
NOTICE:
* When replacing the tire pressure warning ECU, read the transmitter IDs stored in the old ECU using the Techstream and note them down before removal.
* It is necessary to perform the initialization Initialization (from 12/2010) after the registration Registration (from 12/2010) of the transmitter IDs into the tire pressure warning ECU if the ECU has been replaced.
PROCEDURE
1. CHECK HARNESS AND CONNECTOR (DLC3 - TIRE PRESSURE WARNING ECU)
(a) Disconnect the D54 ECU connector.
(b) Measure the resistance according to the value(s) in the table below.
Standard resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE Problem Symptoms Table (from 12/2010)
