Terminals of ecu

1. Skid control ecu

Hint:

*1: W/ 16-inch disc

*2: W/ downhill assist control

*3: For 2wd (w/ auto lsd)

2. Check skid control ecu

1. 1
   Disconnect the a19 ecu connector.
2. 2
   Measure the voltage and resistance of the wire harness side connector.

The voltage cannot be measured with the connector connected to the skid control ecu as the connector is water resistant.

*1: W/ 16-inch disc

*2: W/ downhill assist control

*3: For 2wd (w/ auto lsd)

If the result is not as specified, there may be a malfunction on the wire harness side.

3. Check instrument panel junction block (main body ecu)

1. 1
   Disconnect the id junction block connector.
2. 2
   Measure the resistance of the wire harness side connector.

   

If the result is not as specified, there may be a malfunction on the wire harness side.

1. 1
   Reconnect the id junction block connector.
2. 2
   Measure the voltage of the wire harness side connector.

   

If the result is not as specified, the junction block (ecu) may be a malfunction.
