NOTE:

The displays of CAN communication and P range switch display error detecting condition from memory
erase to the present on “TIME”.
–If error is detected in the past and present error is detected, “CRNT” is displayed.
–If error is detected in the past and present error is not detected, “PAST” is displayed.
–If error has never been detected, nothing is displayed on “TIME”.

Any items other than CAN communication and P range switch count error detection frequency occurred
after erase history to “1-127”.
–If error was detected in the past, error detection frequency from memory erase to the present is displayed
on “TIME”.
–If error has never been detected, nothing is displayed on “TIME”.
–Can clear the detected memory.
Normal: Clear memory in normal condition, history is erased and nothing is displayed on “TIME”.
Error: Clear memory in error condition, error is detected again and “1” is displayed on “TIME”.

1. CHECK FUNCTION
With CONSULT-II
Check operation with “SLIDE PUL SE” on the DATA MONITOR to make sure the pulse changes.
Without CONSULT-II
1. Turn ignition switch OFF.
2. Check signal between driver seat control unit connector and
ground, with oscilloscope.
OK or NG
OK >> Sliding sensor circuit is OK.
NG >> GO TO 2.
2. CHECK SLIDING SENSOR HARNESS CONTINUITY
1. Disconnect driver seat control unit connector and sliding motor connector.
2. Check continuity between driver seat control unit connector
B152 terminals 18 (G), 28C (B/W) and sliding motor B161 termi-
nals 18 (G), 28 (B/W).
3. Check continuity between driver seat control unit B152 terminals
18 (G), 28C (B/W) and ground.
OK or NG
OK >> Replace sliding motor.
