CHECK SLIDING ROOF ECU (SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY)
Disconnect the R6 ECU connector.
Measure the resistance and voltage according to the value(s) in the table below.
| Tester Connection | Wiring Color | Terminal Description | Condition | Specified Condition |
|---|---|---|---|---|
| R6-5 (B) - R6-7 (E) | L - W-B | +B Power supply | Always | 11 to 14 V |
| R6-6 (IG) - R6-7 (E) | V - W-B | Engine switch power supply | Engine switch off | Below 1 V |
| R6-6 (IG) - R6-7 (E) | V - W-B | Engine switch power supply | Engine switch on (IG) | 11 to 14 V |
| R6-7 (E) - Body ground | W-B - Body ground | Ground | Always | Below 1 Ω |
If the result is not as specified, there may be a malfunction on the wire harness side.
Reconnect the R6 ECU connector.
Measure the voltage according to the value(s) in the table below.
| Tester Connection | Wiring Color | Terminal Description | Condition | Specified Condition |
|---|---|---|---|---|
| R6-2 (CHK) - R6-7 (E) | LG - W-B | Sliding roof motor auto operation | Engine switch on (IG), sliding roof switch pushed. | Below 1 V |
| R6-2 (CHK) - R6-7 (E) | LG - W-B | Sliding roof motor auto operation | Engine switch on (IG), sliding roof switch not pushed. | 11 to 14 V |
| R6-9 (OPN) - R6-7 (E) | B - W-B | Sliding roof motor open | Engine switch off, sliding roof switch position [1], [2], [3], [8], [9], [10] | Below 1 V |
| R6-9 (OPN) - R6-7 (E) | B - W-B | Sliding roof motor open | Engine switch on (IG), sliding roof switch position [1], [2], [3], [8], [9], [10] | 11 to 14 V |
| R6-8 (CLS) - R6-7 (E) | SB - W-B | Sliding roof motor close | Engine switch off, sliding roof switch position [1], [2], [3], [4], [5] | Below 1 V |
| R6-8 (CLS) - R6-7 (E) | SB - W-B | Sliding roof motor close | Engine switch on (IG), sliding roof switch position [1], [2], [3], [4], [5] | 11 to 14 V |
| R6-3 (UP) - R6-7 (E) | O - W-B | Sliding roof motor up | Engine switch off, sliding roof switch position [1], [5], [6], [10] | Below 1 V |
| R6-3 (UP) - R6-7 (E) | O - W-B | Sliding roof motor up | Engine switch on (IG), sliding roof switch position [1], [5], [6], [10] | 11 to 14 V |
| R6-4 (DWN) - R6-7 (E) | Y - W-B | Sliding roof motor down | Engine switch off, sliding roof switch position [3], [4], [5], [6], [7], [8] | Below 1 V |
| R6-4 (DWN) - R6-7 (E) | Y - W-B | Sliding roof motor down | Engine switch on (IG), sliding roof switch position [3], [4], [5], [6], [7], [8] | 11 to 14 V |
If the result is not as specified, the ECU or the sliding roof switch may be malfunctioning.
