AUTOMATIC TRANSMISSION (AW30-40LE) 7A–45 • Changes solenoid output pattern as following figure At failure decision Executes following items in addition to above control •Turns Solenoid power supply OFF •Blinks "CHECK TRANS" lamp •Stores the failure information in failure-memory *Prohibits failure detection of S1, S2, SL, STH, Selector position switch, and Oil temp. sensor. Conditions of turning "CHECK TRANS" off: → OFF → ON. Reversion conditions from fail-safe: When a normal judgment is obtained by rechecking At failure decision Recovers at the same time as the conditions of Test description: The following numbers correspond to circled numbers on (1) With the key "ON", the voltage between the TCM terminals (C78-4) and (C78-15 or 19) is 8 to 16V. (2) When the driving wheels revolve with the 3rd speed gear, the voltage is 1 V or less. (3) The solenoid resistance is within the range of 11 to 15 Ω . Diagnostic aids: Shift lever Position Normal S1 failure S2 filure S1 and S2 failure Gear S1 S2 Gear S1 S2 Gear S1 S2 Gear S1 S2 D 1 ❍ × 3 ×→ ❍ 1 ❍ O/D 2 ❍ ❍ ❍ O/D ❍ →× 3 × ❍ ❍ × O/D × × O/D × × 2 1 ❍ × 3 ×→ ❍ 1 ❍ 3 2 ❍ ❍ ❍ O/D ❍ →× 3 × ❍ ❍ × L 1 ❍ × 3 ×→ ❍ 1 ❍ 3 2 ❍ ❍ ❍ O/D ❍ →× |
