System Description
The functions of the fuel and emission control systems are managed by the engine control module (ECM) on vehicles
with manual transmissions or the powertrain control module (PCM) on vehicles with automatic transmissions.
The ECM/PCM detects a failure of a signal from a sensor or another control unit and stores a Temporary DTC or a DTC.
Depending on the failure, a DTC is stored in either the first or the second drive cycle (K20Z3 engine: DTC P0457, turns
on the malfunction indicator lamp (MIL) during the third drive cycle). When a DTC is stored, the ECM/PCM turns on the
malfunction indicator lamp (MIL) by a signal sent to the gauge via F-CAN.  When an abnormality occurs in the signal from a sensor or from another control unit, the ECM/PCM stores a DTC
and turns on the MIL immediately.
 When an abnormality occurs in the signal from a sensor or from another control unit in the first drive cycle, the
ECM/PCM stores a Temporary DTC. If the failure continues in the second drive cycle, the ECM/PCM stores a DTC and
turns on the MIL.
When an abnormality occurs in the signal from a sensor or another control unit, the ECM/PCM ignores the signal and
substitutes a pre-programmed value that allows the engine to continue running. This causes a DTC to be stored and
the MIL to come on.
When the ignition switch is turned to ON (II), the ECM/PCM turns on the MIL via the F-CAN circuit for about 15 to
20 seconds to check the bulb condition. If any readiness codes are not set to complete, the MIL flashes five times. If all
readiness codes are set to complete, the MIL goes off.
After the ignition switch is turned to LOCK (0), the ECM/PCM stays on (about 30 minutes). If the ECM/PCM connector is
disconnected during this time, the ECM/PCM may be damaged. To cancel this mode, disconnect the negative cable
from the battery or jump the SCS line with the HDS after the ignition switch is turned to LOCK (0).

How to Check for DTCs with the SCS Mode
(retrieving the flash codes)

Example: DTC P0717 (15) Short blinks (five)
Example: DTC P0705 (5)

Long blink (one)
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.

Clear A/T DTCs Procedure

(required after any troubleshooting)
Failure Reproduction Technique
14-6Automatic Transmission
General Troubleshooting Information (cont’d)
A
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.
