Inspection Procedure

NOTE: When replacing the master cylinder solenoid, perform zero point calibration (See CALIBRATION ).

INSPECT DLC3 (DLC3 (TC) - DLC3 (CG))

Turn the engine switch on (IG).

Measure the voltage according to the value(s) in the table below.

Standard Voltage

STANDARD VOLTAGE SPECIFICATION

Tester Connection	Switch Condition	Specified Condition
E22-13 (TC) - E22-4 (CG)	Engine switch on (IG)	11 to 14 V

NG: Go to step 4

CHECK CAN COMMUNICATION LINE
1. Turn the engine switch off.
2. Connect the Techstream to the DLC3.
3. Turn the engine switch on (IG) and the Techstream on.
4. Select "CAN Bus Check" from the System Selection Menu screen, and follow the prompts on the screen to inspect the CAN Bus.
  OK: "CAN Bus Check" indicates no malfunctions in CAN communication.

OK: Go to Next Step

CHECK DTC (CAN COMMUNICATION SYSTEM)

Turn the engine switch off.
Connect the Techstream to the DLC3.
Turn the engine switch on (IG) and the Techstream on.

Check for DTCs (See HOW TO PROCEED WITH TROUBLESHOOTING ).
