THEFT DETERRENT / KEYLESS ENTRY: ENGINE IMMOBILISER SYSTEM (w/ Smart Key System): TERMINALS OF ECU

1. CHECK ENGINE SWITCH

(a) Disconnect the D33 engine switch connector.





(b) Measure the resistance according to the value(s) in the table below.

HINT
Measure the values on the wire harness side with the connector disconnected.





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

(c) Reconnect the D33 engine switch connector.

(d) Measure the voltage according to the value(s) in the table below.





If the result is not as specified, the engine switch may have a malfunction.

(e) Inspect using an oscilloscope.

(1) Waveform 1









(2) Waveform 2









(3) Waveform 3









2. CHECK CERTIFICATION ECU

(a) Disconnect the D88 certification ECU connector.





(b) Measure the resistance and voltage according to the value(s) in the table below.

HINT
Measure the values on the wire harness side with the connector disconnected.





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

(c) Reconnect the D88 certification ECU connector.

(d) Measure the resistance and voltage according to the value(s) in the table below.





If the result is not as specified, the certification ECU may have a malfunction.

(e) Inspect using an oscilloscope.

(1) Waveform 1









(2) Waveform 2









(3) Waveform 3









(4) Waveform 4









(5) Waveform 5









3. CHECK STEERING LOCK ECU

(a) Disconnect the D29 steering lock ECU connector.





(b) Measure the resistance and voltage according to the value(s) in the table below.

HINT
Measure the values on the wire harness side with the connector disconnected.





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

4. CHECK ECM

(a) The values listed under "Specified Condition" are reference values. Because waterproof connectors are used for ECM, inspections can not be performed with the connectors connected.









(b) Waveform:

(1) Waveform 1









(2) Waveform 2









5. CHECK POWER MANAGEMENT CONTROL ECU

(a) Disconnect the D89 power management control ECU connector.





(b) Measure the resistance and voltage according to the value(s) in the table below.

HINT
Measure the values on the wire harness side with the connector disconnected.





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

6. COMBINATION METER ASSEMBLY

(a) Disconnect the D18 combination meter assembly connector.





(b) Measure the voltage and resistance according to the value(s) in the table below.

HINT
Measure the values on the wire harness side with the connector disconnected.





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

(c) Reconnect the D18 combination meter assembly connector.

(d) Measure the voltage and resistance according to the value(s) in the table below.





If the result is not as specified, the combination meter assembly may have a malfunction.
