Engine Immobiliser System
TERMINALS OF ECUTerminals Of Control Module/Pinouts:
1. CHECK TRANSPONDER KEY AMPLIFIER
a. Disconnect the I17 amplifier connector, and check the continuity of each terminal of the wire harness side connector.
If the result is not as specified, there may be a malfunction on the wire harness side.
b. Reconnect the I17 amplifier connector, and check the continuity or voltage of each terminal of the connector.
If the result is not as specified, the amplifier may malfunction.
Oscilloscope Waveforms Part 1:
Oscilloscope Waveforms Part 2:
c. Inspect using an oscilloscope.
Terminals Of Control Module/Pinouts:
2. CHECK TRANSPONDER KEY ECU ASSEMBLY
a. Disconnect the T8 ECU connector, and check the voltage or continuity between each terminal of the wire harness side connector.
If the result is not as specified, there may be a malfunction on the wire harness side.
b. Reconnect the T8 ECU connector, and check the voltage between each terminal of the connector.
Oscilloscope Waveforms:
c. Inspect using an oscilloscope.
If the result is not as specified, the T8 ECU may malfunction.
Terminals Of Control Module/Pinouts:
3. CHECK ECM
a. Disconnect the E6, E7 and E8 ECU connectors, and check the voltage or continuity between each terminal of the wire harness side connectors.
Oscilloscope Waveforms:
b. Inspect using an oscilloscope.
If the result is not as specified, there may be a malfunction on the wire harness side.
