As required 45-3 GENERAL SPECIAL TOOLS 45-4 GENERAL GENERAL 45-6 GENERAL TROUBLESHOOTING PROCEDURE GENERAL INFORMATION Functional troubles of the automatic transaxle are caused by the following Inadequate maintenance or adjustment Electronic control function failure Mechanical control function failure Hydraulic control function failure Engine performance failure For troubleshooting, you have to begin with hearing from the client the conditions leading to the trouble and the state of the trouble in as many details as possible and checking if such trouble is reproducible Then, conduct the tests following the inspection procedures shown to the left in order Locate trouble according to “CHART” As shown in the following, conduct basic inspection and make adjustment as necessary (1) Fluid level and condition (2) Manual control cable adjustment (3) Throttle control cable adjustment Perform road test If damper clutch system is found abnormal in road test, check all elements (sensor etc.) one by one and repair as necessary If trouble in hydraulic control system is suspected, make hydraulic pressure test and check If specified hydraulic pressure is not reached in hydraulic pressure test, check valve body and associated parts and hydraulic paths of each system for leaks In case of excessive stains of ATF, abnormal noise, oil leaks, clutch or brake slip or other troubles of transaxle itself, disassemble and check transaxle and repair as necessary 45-7 GENERAL Remarks: *KM171 only indicates items to be given high priority in inspection 45-8 GENERAL Remarks: *KM171 only indicates items to be given high priority in inspection 45-9 GENERAL SERVICE ADJUSTMENT PROCEDURES Diagnosis Automatic transmission malfunctions may be caused by four general conditions; poor engine performance, improper adjustments, hydraulic malfunctions, and mechanical malfunctions Diagnosis of these problems should always begin by checking easily accessible variables; fluid level and condition manual control cable adjustment, and throttle control cable adjustment Then perform road test to determine whether the problem has been corrected or more diagnosis is necessary If the problem still exists after preliminary tests and corrections are completed, hydraulic pressure tests should be performed Fluid Level and Condition Place vehicle on level floor Before removing dipstick, wipe all dirt from area around dipstick With selector lever in “P” Park and parking brakes applied, start engine Engine should be running at idle speed Fluid should be at normal operating temperature [50-80°C (120-180°F)] Move selector lever sequentially to every position to fill torque converter and hydraulic circuit with fluid, then place level in “N” Neutral position This operation is necessary to be sure that fluid level check is accurate Check to see if fluid level is in the “HOT” range on dipstick If fluid is low, add ATF until level reaches “HOT” range Low fluid level can cause a variety of conditions because it allows pump to take in air along with fluid Air trapped in hydraulic circuit forms bubbles which make fluid spongy Therefore, pressures will be erratic Improper filling can also raise fluid level too high When transmission has too much fluid, gears churn up foam and cause same conditions which occur with low fluid level, resulting in accelerated deterioration of ATF In either case, air bubbles can cause overheating, fluid oxidation, and varnishing, which can interfere with normal valve, clutch, and servo operation Foaming can also result in fluid escaping from vent where it may be mistaken for a leak Along with fluid level, it is important to check the condition of the fluid When fluid smells burned, and is contaminated with metal bushing or friction material particles, a complete transmission overhaul is needed Be sure to examine fluid on dipstick closely If there is any doubt about its condition, drain out sample for double check After fluid has been checked, seat dipstick fully to seal out water and dirt 45-10 ... 15 0-2 20 1 5-2 1 4-5 .5 4 0-6 0 8 0-1 00 8-9 .5 10 0-1 20 1 0-1 1 5-6 .5 5 0-7 0 3-4 .5 3 0-5 0 1.5 or more 3 1-4 0 1 6-2 3 1 1-1 6 7-9 2 5-3 0 3 4-3 8 3 2-3 9 2 2-2 5 2 2-2 5 6-7 1 1-1 5 1 1-1 5 1 4-1 6 7. 5-8 .5 1 1-1 5 1 5-1 9 1 5-1 9 9 4-1 01... 15 0-2 20 1 5-2 1 19 0-2 30 1 9-2 2 10 0-1 20 1 0-1 1 15 0-2 20 1 5-2 1 20 0-2 70 2 0-2 6 20 0-2 70 2 0-2 6 1,30 0-1 ,400 12 8-1 38 8 0-1 00 8-9 .5 4 0-6 0 4-5 .5 17 0-2 10 1 7-2 0 8 0-1 00 8-9 .5 10 0-1 20 1 0-1 1 20 0-2 70 2 0-2 6 10 0-1 20 1 0-1 1... 43 0-5 60 4 3-5 5 22 0-3 30 2 2-3 2 15 0-2 20 1 5-2 2 10 0-1 20 1 0-1 2 Refer to the table of components 36 0-4 30 3 5-4 2 46 0-5 30 4 6-5 1 43 0-5 50 4 3-5 3 30 0-3 50 3 0-3 4 30 0-3 50 3 0-3 4 8 0-1 00 8-9 .5 15 0-2 20 1 5-2 1 15 0-2 20
