Troubleshooting Flowcharts

Flowchart No. 1 Symptom Sliding sunroof does not move

Possible cause
^ Burnt SUNROOF 15A fuse
^ Damaged sunroof switch
^ Damaged sunroof relay No.1
^ Damaged sunroof relay No.2
^ Damaged sunroof motor assembly
^ Open or short circuit in wiring harness
^ Poor connection of connector

Step 1

Fuse Inspection:

Action Chart:

Check the SUNROOF 15A fuse in the fuse block

Step 2
1. Remove the overhead console.
2. Turn the ignition switch to ON.

Voltmeter Connection:

Action Chart:

3. Measure the voltage at the (G/O) terminal wire of the sliding sunroof connector.

Step 3
1. Turn the ignition switch to OFF.

Ohmmeter Connection:

Action Chart:

2. Disconnect the sunroof switch connector and check for continuity between the (B) terminal wire of the connector and ground.

Step 4
1. Turn the ignition switch to ON.

Voltmeter Connection:

Action Chart:

2. Measure the voltage at the (G/O) terminal wires of the sunroof relay No.1 and No.2 connectors.

Step 5
1. Turn the ignition switch to OFF.

Ohmmeter Connection:

Action Chart:

2. Disconnect the sunroof relay No.1 and No.2 connectors and check for continuity between the (B) terminal wire of the connectors and ground.

Step 6
1. Turn the ignition switch to ON.

Voltmeter Connection:

Action Chart:

2. Measure the voltage at the (Y/R) and (Y/G) terminal wires of the sunroof relay No.1 and No.2 connectors.

Step 7

Voltmeter Connection:

Reference:

1. Measure the voltage at the terminal wires of the sunroof relay No.1 and No.2 connectors with the following terminal wires grounded.
2. If correct, go to Step 8.
3. If not as specified, check sunroof relays No.1 and No.2.

Voltmeter Connection:

Action Chart:

Step 8
Measure the voltage at the (Y/R) and (Y/G) terminal wires of the sunroof motor assembly connector.

Step 9

Voltmeter Connection:

Reference:

1. Measure the voltage at the terminal wires of the sunroof motor assembly connector with the following terminal wires wounded.
2. If correct, go to Step 10.
3. If not as specified, repair the wiring harness (sunroof relay No.1 and No.2-sunroof motor assembly).

Step 10

Voltmeter Connection:

Reference:

1. Move the slide panel to the following positions by using a screwdriver and measure the voltage at the terminal wires of the sunroof motor assembly connector.
2. If correct, go to Step 11.
3. If not as specified, check the sunroof motor assembly.

Step 11

Voltmeter Connection:

Reference:

1. Move the slide panel to the following positions by using a screwdriver and measure the voltage at the terminal wires of the sunroof switch connector.
2. If correct, check the sunroof switch.
3. If not as specified, repair the wiring harness (sunroof motor assembly-sunroof switch).
