7A2-44 DIAGNOSIS

Terminal Assembly

Inhibitor Switch

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.

ECM

C56 (ECM-A)

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 A26 (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 A26 (C56) to TCM terminal A16 (C94).

•

At throttle position 100% (WOT), OFF duty signal 90% is sent from ECM terminal A26 (C56) to TCM terminal

A16 (C94).
