7B-32 AUTOMATIC TRANSMISSION (4 A/T)
Figure for Step 1
Figure for Step 2, 3, 4
4 Turn ignition switch ON then measure voltage
between terminal “E13-10”, “E13-23” or “E13-
22” of the disconnected harness side TCM cou-
pler and body ground.
Is it about 0 V?
Poor connection at termi-
nal “E13-10”, “E13-23” or
“E13-22” of TCM.
If all the above are in good
condition, substitute a
known-good TCM and
recheck.
“B/R”, “B/O” or “Br” wire or
shift solenoid lead wire
shorted to power source
