TC and CG Terminal Circuit |
DESCRIPTION
Connecting terminals TC and CG of the DLC3 causes the ECU to display the DTC by blinking the ABS warning light and SLIP indicator light.
WIRING DIAGRAM
HINT:
When the warning lights continue to blink, a ground short in the wiring of terminal TC of the DLC3 or an internal ground short in one or more ECUs is suspected.
CAUTION / NOTICE / HINT
NOTICE:
When replacing the brake actuator assembly, perform zero point calibration and store system information (See page
![2016 - 2017 MY Sienna [12/2015 - 11/2017]; BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: CALIBRATION](/t3Portal/stylegraphics/info.gif)
