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:
