## Diagnostic Index

• Use the chart below to verify the symptoms of the trouble in order to diagnose the appropriate area.

No. | TROUBLESHOOTING ITEM | DESCRIPTION | PAGE
--- | --- | --- | ---
1 | • Vehicle does not move in D range, or in R position | • Vehicle does not move when accelerator pedal depressed. | (See NO.1 VEHICLE DOES NOT MOVE IN D RANGE, OR IN R POSITION [JA5AX-EL].)
2 | • Vehicle moves in N position | • Vehicle creeps in N position. • Vehicle creeps if brake pedal not depressed in N position. | (See NO.2 VEHICLE MOVES IN N POSITION [JA5AX-EL].)
3 | • Vehicle moves in P position, or parking gear does not disengage when P is disengaged | • Vehicle rolls when on a downward slope and tires do not lock in P position. • Tires locked when P disengaged, vehicle does not move in D range, and R position when accelerator pedal depressed, and engine remains in stall condition. | (See NO.3 VEHICLE MOVES IN P POSITION, OR PARKING GEAR DOES NOT DISENGAGE WHEN P IS DISENGAGED [JA5AX-EL].)
4 | • Excessive creep | • Vehicle accelerates in D range, and R position without depressing accelerator pedal. | (See NO.4 EXCESSIVE CREEP [JA5AX-EL].)
5 | • No creep at all | • Vehicle does not move in D range, or R position when idling on flat paved road. | (See NO.5 NO CREEP AT ALL [JA5AX-EL].)
6 | • Low maximum speed and poor acceleration | • Vehicle acceleration poor at start. • Delayed acceleration when accelerator pedal depressed while driving. | (See NO.6 LOW MAXIMUM SPEED AND POOR ACCELERATION [JA5AX-EL].)
7 | • No shifting | • Single shift range only. • Sometimes it shifts correctly. | (See NO.7 NO SHIFTING [JA5AX-EL].)
8 | • Does not shift to fifth gear (5GR) | • Vehicle does not upshift from 4GR to 5GR even though vehicle speed increased. • Vehicle does not shift to 5GR even though accelerator pedal released in D range at 60 km/h {37 mph}. | (See NO.8 DOES NOT SHIFT TO FIFTH GEAR (5GR) [JA5AX-EL].)
9 | • Abnormal shifting | • Shifts incorrectly (incorrect shift pattern). | (See NO.9 ABNORMAL SHIFTING [JA5AX-EL].)
10 | • Frequent shifting | • Downshifting occurs immediately even when accelerator pedal depressed slightly in D range. | (See NO.10 FREQUENT SHIFTING [JA5AX-EL].)
11 | • Shift point is high or low | • Shift point considerably different from automatic shift diagram. • Shift delays when accelerating. • Shift occurs quickly when accelerating and engine speed does not increase. | (See NO.11 SHIFT POINT IS HIGH OR LOW [JA5AX-EL].)
12 | • Torque converter clutch (TCC) non-operation | • TCC does not operate when vehicle reaches TCC operation range. | (See NO.12 TORQUE CONVERTER CLUTCH (TCC) NON-OPERATION [JA5AX-EL].)
13 | • No kickdown | • Does not downshift when accelerator pedal fully depressed within kickdown range. | (See NO.13 NO KICKDOWN [JA5AX-EL].)
14 | • Engine flares up or slips when upshifting or downshifting | • When accelerator pedal depressed for driveway, engine speed increases but vehicle speed increase slowly. • When accelerator pedal depressed while driving, engine speed increases but vehicle speed does not increase. | (See NO.14 ENGINE FLARES UP OR SLIPS WHEN UPSHIFTING OR DOWNSHIFTING [JA5AX-EL].)
15 | • Engine flares up or slips when accelerating vehicle | • Engine flares up when accelerator pedal depressed for upshifting. • Engine flares up suddenly when accelerator pedal depressed for downshifting. | (See NO.15 ENGINE FLARES UP OR SLIPS WHEN ACCELERATING VEHICLE [JA5AX-EL].)
16 | • Judder upon torque converter clutch (TCC) operation | • Vehicle jolts when TCC engaged. | (See NO.16 JUDDER UPON TORQUE CONVERTER CLUTCH (TCC) OPERATION [JA5AX-EL].)
17 | • Excessive shift shock from N to D or N to R position/range | • Strong shock felt when shifting from N to D or N to R position/range at idle. | (See NO.17 EXCESSIVE SHIFT SHOCK FROM N TO D OR N TO R POSITION/RANGE [JA5AX-EL].)
18 | • Excessive shift shock is given when upshifting and downshifting | • Excessive shift shock felt when depressing accelerator pedal to accelerate at upshifting. • During cruising, excessive shift shock felt when depressing accelerator pedal at downshifting. | (See NO.18 EXCESSIVE SHIFT SHOCK IS GIVEN WHEN UPSHIFTING AND DOWNSHIFTING [JA5AX-EL].)
19 | • Excessive shift shock on torque converter clutch (TCC) | • Strong shock felt when TCC engaged. | (See NO.19 EXCESSIVE SHIFT SHOCK ON TORQUE CONVERTER CLUTCH (TCC) [JA5AX-EL].)
20 | • Noise occurs at idle when vehicle is stopped in all positions/ranges | • Transaxle noisy in all positions and ranges when vehicle idling. | (See NO.20 NOISE OCCURS AT IDLE WHEN VEHICLE IS STOPPED IN ALL POSITIONS/RANGES [JA5AX-EL].)
21 | • Noise occurs at idle when vehicle is stopped in D range, or in R position | • Transaxle noisy in driving ranges when vehicle idling. | (See NO.21 NOISE OCCURS AT IDLE WHEN VEHICLE IS STOPPED IN D RANGE, OR IN R POSITION [JA5AX-EL].)
22 | • No engine braking in 1GR position of M range | • Engine speed drops to idle but vehicle coasts when accelerator pedal released during cruising at medium to high speeds. • Engine speed drops to idle but vehicle coasts when accelerator pedal released when in M range (1GR) at low vehicle speed. | (See NO.22 NO ENGINE BRAKING IN 1GR POSITION OF M RANGE [JA5AX-EL].)
23 | • Transaxle overheats | • Burnt smell emitted from transaxle. • Smoke emitted from transaxle. | (See NO.23 TRANSAXLE OVERHEATS [JA5AX-EL].)
24 | • Engine stalls when shifted to D range, or in R position | • Engine stalls when shifting from N or P position to D range or R position at idle. | (See NO.24 ENGINE STALLS WHEN SHIFTED TO D RANGE, OR IN R POSITION [JA5AX-EL].)
25 | • Engine stalls when driving at slow speeds or stopping | • Engine stalls when brake pedal depressed while driving at low speed or stopping. | (See NO.25 ENGINE STALLS WHEN DRIVING AT SLOW SPEED OR STOPPING [JA5AX-EL].)
26 | • Starter does not work | • Starter does not work even when P or N position selected. | (See NO.26 STARTER DOES NOT WORK [JA5AX-EL].)
27 | • Gear position indicator light does not illuminate in M range | • Gear position indicator light in instrument cluster does not illuminate in M range and ignition switch at on. | (See NO.27 GEAR POSITION INDICATOR LIGHT DOES NOT ILLUMINATE IN M RANGE [JA5AX-EL].)
28 | • Gear position indicator light illuminates in D range or P, N, R positions | • Gear position indicator light in instrument cluster illuminates in D range or P, N, R positions and ignition switch at on. | (See NO.28 GEAR POSITION INDICATOR LIGHT ILLUMINATES IN D RANGE OR IN P, N, R POSITIONS [JA5AX-EL].)
29 | • Does not shift up in M range | • Gear position indicator light in instrument cluster illuminates but vehicle does not upshift when selector lever is pushed to "+" side. | (See NO.29 DOES NOT SHIFT UP IN M RANGE [JA5AX-EL].)
30 | • Does not shift down in M range | • Gear position indicator light in instrument cluster illuminates but vehicle does not downshift when selector lever is pushed to "-" side. | (See NO.30 DOES NOT SHIFT DOWN IN M RANGE [JA5AX-EL].)
