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 |

Diagnosis Circuit
DESCRIPTION
DTC output mode is set by connecting terminals TC and CG of the DLC3.
DTCs are displayed by blinking the SRS warning light.
HINT:
When each warning light stays blinking, a ground short in the
wiring of terminal TC of the DLC3 or an
internal ground short in each ECU is ...
Disassembly
1. Remove park/neutral position switch assembly
(A) remove the nut, washer and control shaft lever.
(B) using a screwdriver, unstake the nut stopper, and
remove the lock nut and nut stopper.
(c) Remove the 2 bolts and pull out the park/neutral
position switch.
2. REMOVE BREATHER PLUG H ...
Throttle / Pedal Position Sensor / Switch "A"
HINT:
These DTCs relate to the Throttle Position (TP) sensor.
DESCRIPTION
HINT:
This ETC (Electrical Throttle Control System) does not use a throttle cable.
The Throttle Position (TP) sensor is mounted on the throttle body, and detects
the opening angle of the
throttle valve. This sens ...
