ENGINE BRAKE TEST
1) While driving vehicle in 3rd gear of “D” range, shift select lever down to “2” range and check if engine brake
operates.
2) In the same way as in Step 1), check engine brake for operation when select lever is shifted down to “L”
range.
3) Engine brake should operate in above test.
“P” RANGE TEST
1) Stop vehicle on a slope, shift select lever to “P” range and at the same time apply parking brake.
2) After stopping engine, depress brake pedal and release parking brake.
3) Then, release brake pedal gradually and check that vehicle remains stationary.
4) Depress brake pedal and shift select lever to “N” range.
5) Then, release brake pedal gradually and check that vehicle moves.WARNING:
Before test, make sure that there is no vehicle behind so as to pre-
vent rear-end collision.
Test result Possible cause
Fails to operate when shifted down to “2”
rangeDefective shift switch
1st & 2nd brake defective
Direct clutch defective
Fails to operate when shifted down to “L”
range
WARNING:
Before test, check to make sure no one is around vehicle or
down on a slope and keep watchful for safety during test.
Test result Possible cause
Vehicle moves at “P” range or
remains stationary at “N” rangeDefective parking lock pawl or
spring

2. Main fuse 5. Ground
3. Ignition switch 6. A/T relay
DTC DETECTING CONDITION
Automatic transmission doesn’t shift to 1st gear at vehicle start in “D” range.
Step Action Yes No
1 Check voltage between terminal “C44-2” of
TCM coupler and body ground with ignition
switch ON.
Is it 10 – 14 V?Go to Step 2. YEL/BLK wire open or
faulty
A/T relay.
2 Check voltage between terminal “C44-15” of
TCM coupler and body ground with ignition
switch ON.
Is it about 0 V?Poor “C44-2” or “C44-15”
connection.
If all above are OK,
replace known-good TCM
and recheck.“BLK” wire open.
