TERMINALS OF ECU
1. CHECK TRANSPONDER KEY AMPLIFIER
(a) Disconnect the E5 amplifier connector.
(b) Measure the resistance of the wire harness side connector.
If the result is not as specified, there may be a malfunction in the wire harness.
(c) Reconnect the E5 amplifier connector.
(d) Measure the resistance and voltage of the connector.
If the result is not as specified, there may be a malfunction in the amplifier.
(e) Using an oscilloscope, check the waveform 1.
(f) Using an oscilloscope, check the waveform 2.
2. CHECK TRANSPONDER KEY ECU
(a) Disconnect the E46 ECU connector.
(b) Measure the resistance and voltage of the wire harness side connector.
If the result is not as specified, there may be a malfunction on the wire harness side.
(c) Reconnect the E46 ECU connector.
(d) Measure the resistance and voltage of the connector.
If the result is not as specified, there may be a malfunction in the ECU.
(e) Using an oscilloscope, check the waveform 1.
(f) Using an oscilloscope, check the waveform 2.
(g) Using an oscilloscope, check the waveform 3.
(h) Using an oscilloscope, check the waveform 4.
3. CHECK ECM
(a) Measure the resistance and voltage of the wire harness side connector.
If the result is not as specified, there may be a malfunction in the wire harness.
(b) Using an oscilloscope, check the waveform 1.
(c) Using an oscilloscope, check the waveform 2.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
