DIAGNOSIS (JR405E) 7A2-45
Setting Condition:
No range signal is entered from the inhibitor switch with the engine speed over 500 rpm for 2 seconds.
Or
Multiple signals are entered from the inhibitor switch for 1 second.
Fail Safe:
When the vehicle is running, the gear position selected at the trouble detection is held and the lock-up is
inhibited.
After the vehicle stopped, all solenoid operations stop (OFF) and the gear is fixed to the 3rd.
Possible Cause:
Inhibitor switch incorrect adjustment.
Inhibitor switch malfunction.
Open circuit or short circuit to battery between inhibitor switch terminal 2 and TCM terminal A2 (C94), terminal 4
and TCM terminal B19 (C95), terminal 8 and TCM terminal B10 (C95), terminal 5 and TCM terminal B11 (C95),
terminal 1 and TCM terminal A17 (C94), terminal 9 and TCM terminal B2 (B95), or terminal 6 and TCM terminal
B21 (C95), or short between respective harness.
Power supply wire open circuit or short circuit to ground between inhibitor switch terminal 3 and power supply
circuit.
Poor connection of each connector.
Reference:
Following continuity can be measured by circuit tester.

Setting Condition:
No throttle signal is sent from the ECM for 0.4 seconds.
Fail Safe:
When the vehicle is running, the gear position selected at the trouble detection is held and the lock-up is
inhibited.
After the vehicle stopped, all solenoid operations stop (OFF) and the gear is fixed to the 3rd.
Possible Cause:
Throttle position sensor malfunction.
Signal wire open circuit or short circuit to battery of the harness between ECM 29 (C56) and TCM terminal A16
(C94).
Poor connection of each connector.
Reference:
At throttle position 0%, OFF duty signal 10% is sent from ECM terminal 29 (C56) to TCM terminal A16 (C94).
At throttle position 100% (WOT), OFF duty signal 90% is sent from ECM terminal 29 (C56) to TCM terminal A16
(C94).

Setting Condition:
Ground return circuit is failed 7 times continuously after the low & reverse brake duty solenoid output signal turn
on.
Fail Safe:
All solenoid operations are stopped (OFF), the gear is fixed to the 3rd, and the lock-up is inhibited. (In case of
fail-safe valve failure, gear shift to 4th (over-drive) and lock-up are inhibited.)
Possible Cause:
Ground return wire open circuit between terminal assembly terminal 11 and TCM terminal B22 (C95).
Poor connection of each connector.
