16. Install the parts in the reverse order of removal.
17. Do the battery installation procedure (see page
22-69).
18. Turn the ignition switch to ON (II).
19. Manually input the VIN to the ECM/PCM with the HDS.
NOTE: DTC P0630 VIN Not Programmed or
Mismatch may be stored because the VIN has not
been programmed into the ECM/PCM; ignore it,
and continue this procedure.
20. If the READ DATA (engine oil life) failed in step 7, go to step 23 (A/T) or step 26 (M/T). Otherwise, go
to step 21.
21. Select the PGM-FI system with the HDS.
22. Select the REPLACE ECM/PCM MENU, then select WRITE DATA, and follow the screen prompts.
NOTE: If the WRITE DATA indicates FAILED,
continue with this procedure.
23. A/T model: If the READ DATA (ATF life) failed in step 9, go to step 26. Otherwise go to step 24.
24. A/T model: Select the A/T SYSTEM with the HDS.
25. A/T model: Select the REPLACE TCM/PCM MENU, then select WRITE DATA, and follow the screen
prompts.
NOTE: If the WRITE DATA indicates FAILED,
continue with this procedure.
26. Select IMMOBI system with the HDS.
27. Enter the immobilizer code that you got from the iN or use the ECM/PCM replacement procedure in the
HDS; it allows you to start the engine.
28. If the TP POSITION CHECK failed in step 7, clean the throttle body (see page 11- 344), then go to step
29. 29. IftheREADDATAfailedinstep8ortheWRITE
DATA failed in step 22, replace the engine oil
(see page 8-10) and engine oil filter (see page 8-11),
then go to step 30 (A/T) or step 31 (M/T).
30. If the READ DATA failed in step 10 or the WRITE DATA failed in step 27, replace the ATF (see page
14-232), then go to step 31.
31. Select PGM-FI system, and reset the ECM/PCM with the HDS.
32. Update the ECM/PCM if it does not have the latest software (see page 11-227).
33. Do the ECM/PCM idle learn procedure (see page 11-310).

ABS Components
General Troubleshooting Information (cont’d)
 The memory holds all DTCs. However, when the
same DTC is detected more than once, the more
recent DTC is written over the earlier one. Therefore,
when the same problem is detected repeatedly, it is
memorized as a single DTC.
 The DTCs are indicated in the order they occur.
 The DTCs are memorized in the EEPROM. Therefore, the memorized DTCs cannot be erased by
disconnecting the battery. Do the specified
procedures to clear the DTCs.
 Self-diagnosis can be classified into two categories: – Initial diagnosis: Done right after the ignition switch is turned to ON (II) and until the ABS indicator goes
off.
– Regular diagnosis: Done right after the initial diagnosis until the ignition switch is turned to
LOCK (0).
 When the system detects a problem, the ABS modulator-control unit shifts to fail-safe mode.
The pump motor operates when the ABS modulator-
control unit is functioning, and the fluid in the reservoir
is forced out to the master cylinder, causing kickback at
the brake pedal.  The pump motor operates when the ABS modulator- control unit is functioning.
 The ABS modulator-control unit checks the pump motor operation one time after completing initial
diagnosis during regular diagnosis when the vehicle
is driven over 15 km/h (10 mph).
Brake fluid replacement and air bleeding procedures
are identical to the procedures used on vehicles without
ABS (see page 19-9). The troubleshooting procedures assume that the cause
of the problem is still present, and the ABS indicator is
still on. Following a troubleshooting procedure for a
code that has been cleared but does not reset can result
in incorrect diagnosis.
1. Question the client about the conditions when the problem occurred, and try to reproduce the same
conditions for troubleshooting. Find out when the
ABS indicator came on, such as during activation,
after activation, when the vehicle was traveling at a
certainspeed,etc.Ifnecessary,havetheclient
demonstrate the concern.
2. When the ABS indicator does not come on during the test-drive, check for loose connectors, poor
contact of the terminals, etc. in the circuit indicated
by the DTC before you start troubleshooting.
3. After troubleshooting, or the repairs are done, clear the DTCs, and test-drive the vehicle under the same
conditions that originally set the DTCs. Make sure
the ABS indicator does not come on.
4. Check for DTCs from other systems which are connected via F-CAN. If there are DTCs that are
related to F-CAN, one possible cause was that the
ignition switch was turned to ON (II) with the ABS
modulator-control unit connector disconnected.
Clear the DTCs. Check for fuel and emissions DTC’s
first.
NOTE: Always troubleshoot fuel and emissions
DTC’s first.
The term ‘‘intermittent failure’’ means a system may
have had a failure, but it checks OK now. If you cannot
reproduce the condition, check for loose connectors or
terminal pins related to the circuit that you are
troubleshooting.
