NOTE: When checking if the transmission will shift to reverse while the wheels are being driven forward,
raise the vehicle on a lift, make sure it is securely
supported, and allow the front wheels to rotate freely.
 Do not release the clutch pedal if you can select reverse gear while the wheels are driven forward.
 When the vehicle is on a lift, and you make the wheels rotate, turn off the VSA system by the VSA
OFF switch.
1. Turn the ignition switch to LOCK (0).
2. Try to shift the transmission into reverse.
Go to step 4.
Go to step 3.
3. Do the reverse lockout solenoid test (see page 13-77).
Check the change lever assembly (see page
13-105), if necessary inspect the internal
transmission.
Repair or replace the reverse lockout solenoid
(see page 13-77).
4. Start the engine, and try to shift the transmission into reverse.
Intermittent failure, the system is OK at this
time.
Go to step 5. 5. Turn the ignition switch to LOCK (0).
6. Jump the SCS line with the HDS.
7. Disconnect ECM connector A (44P).
8. Disconnect the r

How to Check for DTCs with the Honda
Diagnostic System (HDS)Symptom Troubleshooting Versus DTC
Troubleshooting
14-3
General Troubleshooting Information
A
B
A
When the powertrain control module (PCM) senses an
abnormality in the input or output system, the D
indicator (A) in the gauge control module (tach) (B) will
usually blink.
When the Honda diagnostic system (HDS) is connected
to the data link connector (DLC) (A) located under the
driver’s side of the dashboard and the SCS mode is
selected, it will indicate the diagnostic trouble code
(DTC) when the ignition switch is turned to ON (II) and
the appropriate menu is selected. If the D indicator or the malfunction indicator lamp
(MIL) has been reported on, or if a driveability problem
is suspected, follow this procedure:
1. Connect the HDS to the DLC. (See the HDS user’s manual for specific instructions.)
2. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go
to the DLC circuit troubleshooting (see page
11-204).
3. Select A/T system, and observe the DTC in the DTCs MENU on the HDS screen.
4. Record the freeze data and the on-board snapshots for all fuel and emissions DTCs and A/T DTCs.
5. If there is a fuel and emissions DTC, first check the fuel and emissions system as indicated by the DTC.
6. Clear the DTC and data.
7. Drive the vehicle for several minutes under the
same conditions as those indicated by the freeze
data, and then recheck for a DTC. If the A/T DTC
returns, go to the indicated DTC’s troubleshooting.
If the DTC does not return, there was an
intermittent problem within the circuit. Make sure
all pins and terminals in the circuit are tight.
Some symptoms will not trigger DTCs or cause the D
indicator to blink. If the MIL was reported ON or the D
indicator has been blinking, check for DTCs. If the
vehicle has an abnormal symptom, and there are no
DTCs stored, do the symptom troubleshooting. Check
the list of probable cause(s) for the symptom, in the
sequence listed, until you find the problem.

NOTE: The preferred method is to use the HDS to
retrieve the DTCs.
When the PCM senses an abnormality in the input or
output system, the D indicator (A) in the gauge control
module (tach) (B) will usually blink.
When the D indicator has been reported on, connect the
HDS to the DLC (A) located under the driver’s side of the
dashboard. Turn the ignition switch to ON (II), select
SCS mode, then the D indicator will indicate (flash) the
DTC. If the D indicator and the MIL come on at the same time,
or if a driveability problem is suspected, follow this
procedure:
1. Connect the HDS to the DLC. (See the HDS user’s manual for specific instructions.)
2. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go
to the DLC circuit troubleshooting (see page
11-204).
3. Select SCS mode, then observe the D indicator in the gauge control module (tach). Codes 1 through 9
are indicated by individual short blinks. Codes 10
and above are indicated by a series of long and
short blinks. One long blink equals 10 short blinks.
Add the long and short blinks together to determine
the code.
4. Record all fuel and emissions DTCs and A/T DTCs.
5. If there is a fuel and emissions DTC, first check the fuel and emissions system as indicated by the DTC.
6. Clear the DTC and the data.
7. Drive the vehicle for several minutes under the
same conditions as those indicated by the freeze
data, and then recheck for DTCs. If the A/T DTC
returns, go to the indicated DTC’s troubleshooting.
If the DTC does not return, there was an
intermittent problem within the circuit. Make sure
all pins and terminals in the circuit are tight.

NOTE: The PCM overwrites data and monitors the EVAP
system for about 30 minutes after the ignition switch is
turned to LOCK (0) or ACC (I). Jumping the SCS line
after turning the ignition switch to LOCK (0) or ACC (I)
cancels this function. Disconnecting the PCM during
this function, without jumping the SCS line first, can
damage the PCM.
1. Make sure the ignition switch is turned to LOCK (0), then jump the SCS line with the HDS.
2. Remove the cover (A).
3. Lift up the under-hood fuse/relay box (D).
4. Remove the coolant reservoir (E). Disconnect PCM connectors A, B, and C, and probe the terminals
from the terminal side of the connectors.
NOTE: PCM connectors A, B, and C have symbols
(A= , B= , C= ) embossed on them for
identification. 5. When diagnosis/troubleshooting is done at the
PCM connector, use the terminal test port (A) above
the terminal you need to check.
6. Connect one side of the patch cord’s terminals (A) to a commercially available digital multimeter (B),
and connect the other side cord’s terminals (C) to a
commercially available banana jack (Pomona
Electronics Tool No. 3563 or equivalent) (D).
7. Gently contact the pin probe (male) at the terminal test port from the terminal side. Do not force the
tips into the terminals.
 For accurate results, always use the pin probe (male).
 To prevent damage to the connector terminals, do not insert test equipment
probes, paper clips, or other substitutes as
they can damage the terminals. Damaged
terminals cause a poor connection and an
incorrect measurement.
 Do not puncture the insulation on a wire. Punctures can cause poor or intermittent
electrical connections.

1. Connect the HDS to the DLC (A) located under the
driver’s side of the dashboard.
2. Turn the ignition switch to ON (II).
3. Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting
(see page 11-204).
4. Clear the DTC(s) on the HDS screen.
The OBD status shows the current system status of
each DTC and all of the parameters. This function is
used to see if the technician’s repair was successfully
completed. The results of diagnostic tests for the DTC
are displayed as:  PASSED: The on-board diagnosis is successfully completed.
 FAILED: The on-board diagnosis has finished but failed.
 NOT COMPLETED: The on-board diagnosis was running but is out of the enable conditions of the DTC. NOTE: Reset the PCM with the HDS while the engine is
stopped.
1. Turn the ignition switch to LOCK (0).
2. Turn the ignition switch to ON (II), and wait for 30 seconds.
3. Turn the ignition switch to LOCK (0), and disconnect the HDS from the DLC.
4. Do the PCM idle learn procedure (see page 11-310).
5. Start the engine with the shift lever in P or N, and warm it up to normal operating temperature (the
radiator fan comes on).
6. To verify that the problem is repaired, test-drive the vehicle for several minutes at speeds over 50 km/h
(31 mph) or under the same conditions as those
indicated by the freeze data.
Make sure to follow these points while the vehicle is
raised on a lift for the test-drive.  Disable the VSA by pressing the VSA OFF switch.
 VSA DTC’s may come on when test-driving on a lift. If the VSA DTC(s) come on, clear the DTC(s) with the
HDS.

The PCM actuates A/T clutch pressure control solenoid valves A, B, and C to control the clutch pressure. When shifting
between lower and higher gears, the clutch pressure regulated by A/T clutch pressure control solenoid valves A, B,
and C engages and disengages the clutch smoothly.
The PCM receives input signals from the various sensors and the switches, processes data, and outputs current to A/T
clutch pressure control solenoid valves A, B, and C.
