which TCM require ECM to increase idle speed
OFF: Signal which TCM does not require ECM to
increase idle speed
A/C Switch (ON, OFF): ON: Signal which inform that
air conditioner compressor is turned ON.
OFF: Signal which inform that air conditioner
compressor is turned OFF.
Brake Switch (ON, OFF): Brake light switch position
detected by signal on CAN communication line fed

Road Test
S6JB0A5104012
This test is to check if upshift, downshift and lock-up take place at specified speeds while actually driving vehicle on a
level road.
WARNING
!
• Carry out test in very little traffic area to prevent an accident.
• Test requires 2 persons, a driver and a tester.
1) Warm up engine.
2) With engine running at idle, shift select “D”.
3) Accelerate vehicle speed by depressing accelerator pedal gradually.
4) While driving in “D” range, check if gear shift and lock-up occur properly as shown in “Automatic Gear Shift Table”.
