Diagnosis System
DIAGNOSIS SYSTEM
1. DESCRIPTION
(a) The steering lock ECU (steering lock actuator or UPR bracket assembly) stores
DTCs when a malfunction occurs in the system. These DTCs can be confirmed by using
the Techstream.
NOTICE:
When using the Techstream with the engine switch off to confirm ...

1. DATA LIST
HINT:
Using the Techstream to read the Data List allows the values or states of switches,
sensors, actuators and other items to be read without removing any parts. This non-intrusive
inspection can be very useful because intermittent conditions or signals ...
