DESCRIPTION
DTC output mode is set by connecting terminals TC and CG of the DLC3.
WIRING DIAGRAM
HINT:
When each warning light continues blinking, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in each ECU is suspected.
CAUTION / NOTICE / HINT
NOTICE:
When replacing the master cylinder solenoid, perform calibration (See page ).
PROCEDURE
1. |
INSPECT DLC3 |
(a) Turn the ignition switch to ON.
(b) Measure the voltage according to the value(s) in the table below. Standard Voltage:
|
|
NG |
GO TO STEP 4 |
|
2. |
CHECK CAN COMMUNICATION LINE |
(a) Turn the ignition switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the ignition switch to ON.
(d) Turn the Techstream on.
(e) Select CAN Bus Check from the System Selection Menu screen and follow the
prompts on the screen to inspect the CAN bus (See page
).
OK:
