Toyota RAV4 (XA40) 2013-2018 Service Manual: Tc and cg terminal circuit
Description
Dtc output mode is set by connecting terminals 13 (tc) and 4 (cg) of the dlc3. The dtcs are indicated by the blinking of the tire pressure warning light.
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 may have occurred.
Inspection procedure
Notice:
It is necessary to register an id code after replacing the tire pressure monitor valve and/or the tire pressure warning ecu (see page tw-9).
- Check wire harness (dlc3 - ecu)
- Disconnect the e13 dlc3 connector.
- Disconnect the e56 ecu connector.
- Measure the resistance of the wire harness side connectors.

Fuel pump control circuit
Description
When the engine is cranked, the starter relay drive signal output from the
star terminal of the ecm is
input into the sta terminal of the ecm, and ne signal generated by the
crankshaft position sensor is also
input into the ne+ terminal. Thus, the ecm interprets that the engine is ...
Stuck in deceleration sensor
Description
The skid control ecu receives signals from the yaw rate and deceleration
sensor via the can
communication system.
The yaw rate sensor has a built-in deceleration sensor and detects the vehicle's
condition using 2 circuits
(gl1: g sensor 1, gl2: g sensor 2).
If there is t ...
