TS and CG Terminal Circuit
BRAKE CONTROL / DYNAMIC CONTROL SYSTEMS: VEHICLE STABILITY CONTROL SYSTEM: TS and CG Terminal Circuit
- TS and CG Terminal Circuit
DESCRIPTION
In the Test Mode (signal check), a malfunction in the speed sensor that cannot be detected when the vehicle is stopped can be detected while driving.
Transition to the sensor check mode can be performed by connecting terminals TS and CG of the DLC3 and turning the ignition switch from off to ON.

B -- CHECK POWER STEERING ECU (TS of DLC3 INPUT)
A -- Continue to next step.
3. CHECK HARNESS AND CONNECTOR (TS of DLC3 - POWER STEERING ECU)
(a) Turn the ignition switch off.
(b) Disconnect the ECM connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
4. CHECK HARNESS AND CONNECTOR (CG of DLC3 - BODY GROUND)
(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
5. CHECK POWER STEERING ECU (TS of DLC3 INPUT)
SST : 09843-18040
(a) Turn the ignition switch off.
(b) Reconnect the power steering ECU connector.
(c) Using SST, connect terminals TS and CG of the DLC3.
(d) Turn the ignition switch to ON.
(e) Check that the PS warning light is blinking.
