| 2. | CHECK HARNESS AND CONNECTOR (LUGGAGE CLOSER MOTOR ASSEMBLY - LUGGAGE DOOR CLOSER ASSEMBLY) |
(a) Disconnect the R7 luggage closer motor assembly connector.
(b) Disconnect the R18 luggage door closer assembly connector.
(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| R7-16 (CSG) - R18-4 (CPSE) | Always | Below 1 Ω |
| R7-17 (CS2) - R18-9 (CPS2) | Always | Below 1 Ω |
| R7-18 (CS1) - R18-2 (CPS1) | Always | Below 1 Ω |
| R7-19 (CSV) - R18-3 (CPS+) | Always | Below 1 Ω |
| R7-16 (CSG) or R18-4 (CPSE) - Body ground | Always | 10 kΩ or higher |
| R7-17 (CS2) or R18-9 (CPS2) - Body ground | Always | 10 kΩ or higher |
| R7-18 (CS1) or R18-2 (CPS1) - Body ground | Always | 10 kΩ or higher |
| R7-19 (CSV) or R18-3 (CPS+) - Body ground | Always | 10 kΩ or higher |
| NG | | REPAIR OR REPLACE HARNESS OR CONNECTOR |
|
| 3. | CHECK LUGGAGE CLOSER MOTOR ASSEMBLY |
(a) Measure the resistance according to the value(s) in the table below.
Standard Resistance:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| R18-4 (CPSE) - Body ground | Always | Below 1 Ω |
(b) Measure the voltage according to the value(s) in the table below.
Standard Voltage:
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| R18-2 (CPS1) - Body ground | Engine switch on (IG), power trunk lid not operate | 7 V or higher |
| R18-3 (CPS+) - Body ground | Engine switch on (IG), power trunk lid not operate | 7 V or higher |
| R18-9 (CPS2) - Body ground | Engine switch on (IG), power trunk lid not operate | 7 V or higher |
| NG | | REPLACE LUGGAGE CLOSER MOTOR ASSEMBLY |
|
| 4. | CHECK LUGGAGE DOOR CLOSER ASSEMBLY |
(a) Disconnect R18-8 (M+) and R18-1 (M-) from the luggage door closer assembly connectors.
(b) Reconnect the R18 luggage door closer assembly connector.
(c) Using an oscilloscope, check the waveform.
| *a | Component with harness connected (Luggage Door Closer Assembly) | *b | Waveform 1 |
| *c | Waveform 2 | - | - |
NOTICE:
Do not operate any other functions until this inspection is finished.
OK:
| Tester Connection | Condition | Tool Setting | Specified Condition |
|---|---|---|---|
| R18-2 (CPS1) - Body ground |
| 2 V/DIV., 10 ms./DIV. | Pulse generation (waveform 1) |
| R18-9 (CPS2) - Body ground |
| 2 V/DIV., 10 ms./DIV. | Pulse generation (waveform 2) |
| OK | | REPLACE LUGGAGE CLOSER MOTOR ASSEMBLY |
| NG | | REPLACE LUGGAGE DOOR CLOSER ASSEMBLY |
