Manual Shifting Test
HINT: With this test, it can be determined whether the trouble lies within the electrical circuit or is a mechanical problem in the transmission.
1. DISCONNECT ECT ECU CONNECTOR
(a) Remove the cowl side trim of passenger side.
(b) With the engine OFF, disconnect the ECT ECU connector.
2. INSPECT MANUAL DRIVING OPERATION
Check that the shift and gear positions correspond with the table below.
Shift position | D range | 2 range | L range | R range | P range
Gear position | O/D | 3rd | 1st | Reverse | Pawl Lock
HINT: If the L, 2 and D range gear positions are difficult to distinguish, perform the following road test.
• While driving, shift through the L, 2 and D ranges. Check that the gear change corresponds to the shift position.
If any abnormality is found in the above test, the problem lies in transmission itself.
3. CONNECT ECT ECU CONNECTOR
(a) Connect the ECT ECU connector.
(b) Install the cowl side trim of passenger side.
