NG --> See step 3 OK: Go to next step
2. PERFORM ACTIVE TEST USING TECHSTREAM (WASHER LEVEL WARNING LIGHT) Operate the Techstream according to the display and select Active Test. Refer to «DATA LIST / ACTIVE TEST [05/2013 - ]»(ref-615349-S00807021412014050900000) . COMBINATION METER Tester Display Test Part Control Range Diagnostic Note Indicat. Lamp Washer Washer level warning light ON/OFF - OK Washer level warning light condition can be switched by Active Test. NG --> See step 5 OK: Go to next step
3. INSPECT LEVEL WARNING SWITCH ASSEMBLY Remove the level warning switch. Refer to «REMOVAL [05/2013 - ]»(ref-615279-S41819563762014050900000) . Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition 1 (S) - 2 (E) Fluid volume is more than 900 cc (54.9 cu.in.) 10 kohms or higher 1 (S) - 2 (E) Fluid volume is less than 500 cc (30.5 cu.in.) Below 1 ohms HINT: When the fluid volume is between 500 and 900 cc (30.5 and 54.9 cu.in.), the level warning switch may be on or off. NG --> See step 6 OK: Go to next step
4. CHECK HARNESS AND CONNECTOR (LEVEL WARNING SWITCH ASSEMBLY - COMBINATION METER ASSEMBLY AND BODY GROUND) Disconnect the A17 level warning switch connector. Disconnect the C50 combination meter connector. Measure the resistance according to the value(s) in the table below. Standard Resistance Tester Connection Condition Specified Condition A17-1 (S) - C50-15 (WLVL) Always Below 1 ohms A17-2 (E) - Body ground Always Below 1 ohms A17-1 (S) - Body ground Always 10 kohms or higher NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK --> See step 5
5. PROCEED TO NEXT SUSPECTED AREA SHOWN IN PROBLEM SYMPTOMS TABLE. Refer to «PROBLEM SYMPTOMS TABLE [05/2013 - 01/2014]»(ref-615349-S36773076442014050900000)
