DIAGNOSTICS ABS WITH EBD & BA & TRC & VSC SYSTEM
TS TERMINAL CIRCUIT
CIRCUIT DESCRIPTION
The sensor check circuit detects troubles in the sensor signal which cannot be detected by the DTC check.
Connecting terminals Ts and CG of the DLC3 starts the check.

INSPECTION PROCEDURE
1 INSPECT DLC3 TERMINAL VOLTAGE(Ts TERMINAL)
(a) Turn the ignition switch ON.
(b) Measure the voltage between terminals Ts and CG of the
DLC3.
OK:
Voltage: 10 to 14 V

TermsMeaning
Physical addressThree±digit code (shown in hexadecimal) which is given to each component com-
prising the AVC±LAN.
Corresponding to the function, individual symbols are specified.
Logical addressTwo±digit code (shown in hexadecimal) which is given to each function comprising
the inner system of the AVC±LAN.
1. RADIO RECEIVER ASSY (Physical address: 190)
HINT:

*1: Even if no failure is detected, trouble code may be stored depending on the battery condition or
voltage for starting the engine.

*2: It is stored when 180 seconds have passed after the power supply connector is pulled out after the
engine starts.

*3: It may be stored when the engine key is turned 1 minuite after the engine starts.

*4: It may be stored when the engine key is turned again after the engine starts.

*5: When 210 seconds have passed after pulling out the power supply connector of the master compo-
nent with the ignition switch in ACC or ON, this code is stored.
(a) Logical address: 01 (Communication control)

shown by code.
(If not, delete DTC and recheck.)
