Toyota RAV4 (XA40) 2013-2018 Service Manual: Security indicator light circuit
Description
When the transponder key is registered, the transponder key ecu indicates the key registration condition by lighting up, blinking or turning off the security indicator.
Wiring diagram
Inspection procedure
- Perform active test by intelligent tester (security indicator light)
- Select the active test, use the intelligent tester (with can vim) to generate a command, and then check that the security indicator light operation is normal.
Ok: security indicator light turns on / off.
- Check wire harness (transponder key ecu - security indicator light)
- Disconnect the e46 ecu connector.
- Disconnect the e22*1 or e23*2 light connector.
- Measure the resistance of the wire harness side connectors.
Hint:
*1: For manual air conditioning system
*2: For automatic air conditioning system
Standard resistance:
for manual air conditioning system 
For automatic air conditioning system
- Inspect transponder key ecu (output)
- Remove the transponder key ecu with its connectors still connected.
- Measure the voltage of the ecu.
Standard voltage 
Replace clock sub-assembly (for manual air conditioning system), heater control panel (for automatic air conditioning system)

Driving in vehicle-to-vehicle distance control mode
This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current vehicle-to-
vehicle following distance, and operates to maintain a suitable following
distance from the vehicle ahead. The desired vehicle-to-vehicle
distance can also be se ...
