1. PERFORM MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring the stall speeds in the D position.
NOTICE:
|
(1) Chock the 4 wheels.
(2) Connect the intelligent tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot pressed firmly on the brake pedal.
(5) Start the engine.
(6) Shift into the D position. Press all the way down on the accelerator pedal with your right foot.
(7) Quickly read the stall speed at this time.
Stall speed: 2,300 +- 150 rpm
Evaluation:
Problem | Possible cause |
(a) Stall engine speed is low in D position |
HINT: If the value is less than the specified value by 600 rpm or more, the torque converter could be faulty. |
(b) Stall engine speed is high in D position |
|
(b) Measure the time lag.
(1) When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag before the shock can be felt. This is used for checking the condition of the clutch and brake.
NOTICE:
|
(2) Connect the intelligent tester together with the CAN VIM (controller area network vehicle interface module) to the DLC3.
(3) Fully apply the parking brake.
(4) Start and warm up the engine and check idle speed.
Idle speed: approx. 700 rpm (In N position and A/C OFF)
(5) Shift the lever from N to D position. Using a stop watch, measure the time from when the lever is shifted until the shock is felt.
Time lag: N → D less than 1.2 seconds
(6) In the same way, measure the time lag for N → R.
Time lag: N → R less than 1.5 seconds
Evaluation (If N → D or N → R time lag is longer than the specified):
Problem | Possible cause |
N → D time lag is longer |
|
N → R time lag is longer |

Internal Control Module Random Access Memory (RAM) Error
DESCRIPTION
The ECM continuously monitors its own internal memory status, internal
circuits, and output signals
transmitted to the throttle actuator. This self-check ensures that the ECM is
functioning properly. If any
malfunction is detected, the ECM sets the appropriate DTC and illumina ...
