CHECK SLIDING ROOF ECU (SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY)
Disconnect the T2 ECU connector.
Measure the resistance and voltage according to the value(s) in the table below.
Tech Tips
Measure the values on the wire harness side with the connector disconnected.
| Tester Connection | Wiring Color | Terminal Description | Condition | Specified Condition |
|---|---|---|---|---|
| T2-1 (B) - T2-2 (E) | P - W-B | +B Power supply | Power switch off | 11 to 14 V |
| T2-5 (IG) - T2-2 (E) | R - W-B | Power switch power supply | Power switch off | Below 1 V |
| T2-5 (IG) - T2-2 (E) | R - W-B | Power switch power supply | Power switch on (IG) | 11 to 14 V |
| T2-2 (E) - Body ground | W-B - Body ground | Ground | Always | Below 1 Ω |
If the result is not as specified, there may be a malfunction in the wire harness.
Reconnect the T2 ECU connector.
Measure the voltage according to the value(s) in the table below.
| Tester Connection | Wiring Color | Terminal Description | Condition | Specified Condition |
|---|---|---|---|---|
| T2-7 (OPN) - T2-2 (E) | GR - W-B | Sliding roof motor open | Power switch on (IG), SLIDE OPEN switch ON | Below 1 V |
| T2-7 (OPN) - T2-2 (E) | GR - W-B | Sliding roof motor open | Power switch on (IG), SLIDE OPEN switch OFF | 11 to 14 V |
| T2-9 (CLS) - T2-2 (E) | B - W-B | Sliding roof motor close | Power switch on (IG), SLIDE CLOSE switch ON | Below 1 V |
| T2-9 (CLS) - T2-2 (E) | B - W-B | Sliding roof motor close | Power switch on (IG), SLIDE CLOSE switch OFF | 11 to 14 V |
| T2-10 (UP) - T2-2 (E) | SB - W-B | Sliding roof motor up | Power switch on (IG), TILT UP switch ON | Below 1 V |
| T2-10 (UP) - T2-2 (E) | SB - W-B | Sliding roof motor up | Power switch on (IG), TILT UP switch OFF | 11 to 14 V |
| T2-8 (DWN) - T2-2 (E) | G - W-B | Sliding roof motor down | Power switch on (IG), TILT DOWN switch ON | Below 1 V |
| T2-8 (DWN) - T2-2 (E) | G - W-B | Sliding roof motor down | Power switch on (IG), TILT DOWN switch OFF | 11 to 14 V |
If the result is not as specified, the sliding roof ECU (sliding roof drive gear sub-assembly) may have a malfunction.
