NG --> See step 2 OK --> END
2. REPLACE INTEGRATION CONTROL AND PANEL ASSEMBLY. Refer to «REMOVAL - Step 10»(ref-382835-S32109658782011012800000)

1. CHECK OUTER MIRROR CONTROL SWITCH FUNCTION (POWER MIRROR CONTROL FUNCTION) Check that the mirror surface positions of the outer rear view mirror LH and RH can be moved using the mirror control switch of the integration control and panel assembly. OK Mirror surface positions of the outer rear view mirror LH and RH can be moved using the mirror control switch of the integration control and panel assembly. NG --> GO TO PROBLEM SYMPTOMS TABLE OK: Go to next step
2. CHECK SEAT MEMORY SWITCH FUNCTION (MIRROR MEMORY FUNCTION) Check that the outer rear view mirror LH and RH positions can be memorized using the seat memory switch. OK Outer rear view mirror LH and RH positions can be memorized using seat memory switch. NG --> GO TO FLOWCHART OK: Go to next step
3. CHECK SEAT MEMORY SWITCH FUNCTION (DRIVER SEAT) (SEAT MEMORY FUNCTION) Check that the driver side seat can be moved using the seat memory switch. OK Driver side seat can be moved using seat memory switch. NG --> GO TO FRONT POWER SEAT CONTROL SYSTEM OK: Go to next step
4. READ VALUE USING TECHSTREAM (MIRROR POSITION SENSOR) Check the DATA LIST for proper functioning of the mirror position sensor. Front multiplex network door ECU LH, RH Tester Display Measurement Item/Display Normal Condition Diagnostic Note Mirror Position Sensor (V) Vertical mirror position / Min.: 0, Max.: 5 V Within 0 to 5 V - Mirror Position Sensor (H) Horizontal mirror position / Min.: 0, Max.: 5 V Within 0 to 5 V - OK Output voltage is as shown in table above. OK --> REPLACE POSITION CONTROL ECU AND SWITCH ASSEMBLY LH NG: Go to next step
5. INSPECT OUTER MIRROR ACTUATOR ASSEMBLY (MIRROR POSITION SENSOR) Disconnect the z5 or z6 mirror connector. Apply battery and dry cell battery voltage to the terminals as shown in the table below. Measure the voltage while the mirror moves between the fully downward and fully upward positions. Standard voltage Outer rear view mirror assembly LH (driver side) Outer rear view mirror assembly RH (passenger side) Measurement Connection (Battery) Measurement Connection (Dry Cell Battery) Voltmeter Condition Mirror Condition Specified Condition Battery positive (+) --> Terminal 10 (M+) Battery negative (-) --> Terminal 1 (MV) Battery positive (+) --> Terminal 5 (VC) Battery negative (-) --> Terminal 14 (E1) Positive (+) lead --> Terminal 6 (VSSL) Negative (-) lead --> Terminal 14 (E1) Turns fully downward 0 to 1.0 V Battery positive (+) --> Terminal 1 (MV) Battery negative (-) --> Terminal 10 (M+) Battery positive (+) --> Terminal 5 (VC) Battery negative (-) --> Terminal 14 (E1) Positive (+) lead --> Terminal 6 (VSSL) Negative (-) lead --> Terminal 14 (E1) Turns fully upward 2.8 to 5.0 V Measurement Connection (Battery) Measurement Connection (Dry Cell Battery) Voltmeter Condition Mirror Condition Specified Condition Battery positive (+) --> Terminal 10 (M+) Battery negative (-) --> Terminal 1 (MV) Battery positive (+) --> Terminal 5 (VC) Battery negative (-) --> Terminal 14 (E1) Positive (+) lead --> Terminal 6 (VSSR) Negative (-) lead --> Terminal 14 (E1) Turns fully downward 0 to 1.0 V Battery positive (+) --> Terminal 1 (MV) Battery negative (-) --> Terminal 10 (M+) Battery positive (+) --> Terminal 5 (VC) Battery negative (-) --> Terminal 14 (E1) Positive (+) lead --> Terminal 6 (VSSR) Negative (-) lead --> Terminal 14 (E1) Turns fully upward 2.8 to 5.0 V Measure the voltage while the mirror moves between the fully left and fully right positions. Standard voltage Outer rear view mirror assembly LH (driver side) Outer rear view mirror assembly RH (passenger side) Measurement Connection (Battery) Measurement Connection (Dry Cell Battery) Voltmeter Condition Mirror Condition Specified Condition Battery positive (+) --> Terminal 9 (MH) Battery negative (-) --> Terminal 10 (+M) Battery positive (+) --> Terminal 5 (VC) Battery negative (-) --> Terminal 14 (E1) Positive (+) lead --> Terminal 13 (HSSL) Negative (-) lead --> Terminal 14 (E1) Turns to left fully 2.8 to 5.0 V Battery positive (+) --> Terminal 10 (M+) Battery negative (-) --> Terminal 9 (MH) Battery positive (+) --> Terminal 5 (VC) Battery negative (-) --> Terminal 14 (E1) Positive (+) lead --> Terminal 13 (HSSL) Negative (-) lead --> Terminal 14 (E1) Turns to right fully 0 to 1.0 V Measurement Connection (Battery) Measurement Connection (Dry Cell Battery) Voltmeter Condition Mirror Condition Specified Condition Battery positive (+) --> Terminal 9 (MH) Battery negative (-) --> Terminal 10 (M+) Battery positive (+) --> Terminal 5 (VC) Battery negative (-) --> Terminal 14 (E1) Positive (+) lead --> Terminal 13 (HSSR) Negative (-) lead --> Terminal 14 (E1) Turns to left fully 0 to 1.0 V Battery positive (+) --> Terminal 10 (M+) Battery negative (-) --> Terminal 9 (MH) Battery positive (+) --> Terminal 5 (VC) Battery negative (-) --> Terminal 14 (E1) Positive (+) lead --> Terminal 13 (HSSR) Negative (-) lead --> Terminal 14 (E1) Turns to right fully 2.8 to 5.0 V Result Result Proceed to Outer rear view mirror LH operates normally A Outer rear view mirror RH operates normally B Outer rear view mirror LH does not operate normally C Outer rear view mirror RH does not operate normally D D --> REPLACE OUTER MIRROR ACTUATOR ASSEMBLY RH C --> REPLACE OUTER MIRROR ACTUATOR ASSEMBLY LH B --> REPLACE FRONT MULTIPLEX NETWORK DOOR ECU RH A --> REPLACE FRONT MULTIPLEX NETWORK DOOR ECU LH

1. CHECK INTEGRATION CONTROL AND PANEL ASSEMBLY FUNCTION (MIRROR MASTER SWITCH FUNCTION) Check that the outer rear view mirror assembly LH and RH can be moved using the mirror master switch of the integration control and panel assembly. OK Outer rear view mirror assembly LH and RH can be moved using mirror master switch of integration control and panel assembly. NG --> GO TO PROBLEM SYMPTOMS TABLE OK: Go to next step
2. CHECK OPERATION OF SHIFT INDICATOR Check that the shift indicator of the combination meter operates normally. OK Shift indicator of combination meter operates normally. NG --> GO TO COMBINATION METER OK: Go to next step
