Sliding Roof ECU Power Source Circuit

SLIDING ROOF: SLIDING ROOF SYSTEM: Sliding Roof ECU Power Source Circuit
- Sliding Roof ECU Power Source Circuit

DESCRIPTION

The sliding roof drive gear sub-assembly (sliding roof control ECU) receives signals from the sliding roof switch and activates the sliding roof. However, malfunctions in the fuse, wire harness or sliding roof drive gear sub-assembly (sliding roof control ECU) may cause the sliding roof system to stop operating.

INSPECTION PROCEDURE

PROCEDURE

1. PERFORM ACTIVE TEST USING TECHSTREAM (SLIDING ROOF OPERATION)

(a) Select the ACTIVE TEST, use Techstream to generate a control command, and then check that the sliding roof slides open/close and tilts up/down.

Sliding roof ECU:





OK
Sliding roof operates normally.

NG -- INSPECT FUSE (S/ROOF, ECU-IG NO. 1)

OK -- REPLACE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (SLIDING ROOF CONTROL ECU)

2. INSPECT FUSE (S/ROOF, ECU-IG NO. 1)

(a) Remove the S/ROOF and ECU-IG No. 1 fuses from the instrument panel J/B.

(b) Measure the resistance of the fuses.

Standard resistance:

Below 1 Ohms

NG -- REPLACE FUSE
OK -- Continue to next step.

3. CHECK WIRE HARNESS (SLIDING ROOF CONTROL ECU - BATTERY AND BODY GROUND)

(a) Disconnect the Q13 connector.





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

Standard voltage:





Standard resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR

OK -- REPLACE SLIDING ROOF DRIVE GEAR SUB-ASSEMBLY (SLIDING ROOF CONTROL ECU)
