2. Remove the TCM, and turn it over.
3. Inspect the circuit on the TCM according to the troubleshooting flowchan with the special tool and a digital multime-
ler as shown.
How to uss the Blckprobr Sat
Connect the backprobe adapters to the st8cking patch cords, and connect the cord to a multimeter. Using the wire
insulation as a guide for the contoured tip of the backprobe adapter, g€ntly slide the tip into the connector from the
wire until it comes in contact with the terminal end oJ the wire.

TCM Reset Procodure
1. Turn the ignition switch OFF.
2. Remove the No. 47 BACK UP fuse {7.8 A) from the under-hood fuse/relay box for lO seconds to reset the TCM.
NOTE:
. Disconnecting the No, 47 BACK UP fuse also cancels the radio anti-theft code, preset stations and clock setting, Get thecustomer's code number, and make note of the rsdio presets before removing the fuse so you can reset them.o The TCM memory cannot be cleared by using the OBD ll Scan Tool or Honda pGM Tester; be sure to remove the BACKUP fuse to reset the TCM.

Lock-up Control Solenoid Valve A/B Assembly
NOTE: Lock-up control solenoid valves A and B must be
removed/replaced as an assembly.
L Disconnect 2P connector from the lock-up control
solenoid valve Ay'B assembly.
2. Measure the resistance between the No. 2 terminal
{solenoid valve A) of the lock-up control solenoid
valve connector and body ground, and between the
No. 1 terminal {solenoid valve B) and body ground.
STANDARD: 12 - 25 O
LOCK.UP CONTROLSOLENOID VALVE A/BASSEMBLY
Replace the lock-uo control solenoid valve assem-
bly if the resistance is out of specification.
lf the resistance is within the standard, connect the
No. 1 terminal of the lock-uD control solenoid valve
connector to the battery positive terminal. A clicking
sound should be hea.d. Connect the No. 2 terminal to
the battery positive terminal. A clicking sound should
be heard. Replace the lock-up control solenoid valve
assembly if no clicking sound is heard.
1.Remove the mounting bolts and lock-up control
solenoid valve A/B assemblv.
Check the lock-up control solenoid valve fluid pas-
sages for dust or dirt. and replace as an assembly, if
necessary.

NOTE: Shift control solenoid valves A and B must be
removed/replaced as an assembly.
l. Disconnect 3P connector from the shift control
solenoid valve A,/B assembly.
2. Measure the resistance between the No. 1 terminal
(solenoid valve A) of the shift control solenoid valve
connector and body ground, and between the No. 3
terminal (solenoid valve B) and body ground.
STANDARD: 12 - 25 o
Replace the shift control solenoid valve assembly if
the resistance is out of sDecification.
lf the resistance is within the standard, connect the
No. 1 terminal of the shift control solenoid valve con-
nector to the battery positive terminal. A clicking
sound should be heard. Connect the No. 3 terminal to
the battery positive terminal. A clicking sound should
be heard. Replace the shift control solenoid valve
assembly if no clicking sound is heard.

Pressure Testing
a While testing, be careJulot the rotating front wheels.
a Make sule litts, iacks, and safety stands are placed
properly (see section 1).
CAUTION: Befoie testing, be sure the transmission fluid
is filled to the proper level.
'1. Raise the vehicle {see section 'll.
2. Warm up the engine (the radiator fan comes on),
then stop the engine and connect a tachometer.
3. Connect the special tool to each inspection hole(s).
TOROUE: 18 N.m l1-8 kgt.m, 13lbf.ftl
CAUTION: Connect the A/T pressure gauge secure-
ly, be sure not to allow dust and olher foreign pani-
cles to enter the inspection hole.
