Engine Immobilizer System (W/ Smart Key System)
TERMINALS OF ECUTerminals Of ECU/Pinouts:
1. CHECK KEY SLOT
a. Disconnect the K3 key slot connector.
b. Measure the resistance of the terminal of the wire harness side connector.
Standard:
If the result is not as specified, the wire harness side may have a malfunction.
c. Reconnect the K3 key slot connector.
d. Measure the resistance and voltage of each terminal of wire harness side connector.
Standard:
If the result is not as specified, the key slot (amplifier) may have a malfunction.
