TCM SELF-DIAGNOSTIC PROCEDURE
Description
If a malfunction occurs in electrical system, turning ignition switch ON will illuminate OD OFF indicator lamp for
2 seconds. To detect a malfunction, entering a self-diagnosis start signal retrieves information on malfunctions
from memory and indicates malfunction by blinking OD OFF indicator lamp.
Diagnostic Procedure
1. CHECK OD OFF INDICATOR LAMP
1. Park vehicle on flat surface.
2. Move selector lever to “P” position.
3. Turn ignition switch OFF. Wait at least 5 seconds.
4. Turn ignition switch ON. (Do not start engine.)
Does OD OFF indicator lamp come on about 2 seconds?
YES >> GO TO 2.
NO >> Stop procedure. Perform AT-198, "
OD OFF Indicator
Lamp Does Not Come On" before proceeding.
2. JUDGEMENT PROCEDURE STEP 1
1. Turn ignition switch OFF.
2. Keep pressing shift lock release button.
3. Move selector lever from “P” to “D” position.
4. Turn ignition switch ON. (Do not start engine.)
5. Keep pressing overdrive control switch while OD OFF indicator lamp is lighting up for 2 seconds. (OD
OFF indicator lamp is on.)
6. Keep pressing overdrive control switch and shift selector lever to the “2” position. (OD OFF indicator lamp
is on.)
7. Stop pressing overdrive control switch. (OD OFF indicator lamp is on.)
8. Shift selector lever to the “1” position. (OD OFF indicator lamp is on.)
9. Keep pressing overdrive control switch. (OD OFF indicator lamp is off.)
10. Depress accelerator pedal fully while pressing overdrive control switch.

SHIFT CONTROL SYSTEM
Revision: June 20062007 Versa
Checking of A/T PositionUCS005VL
1. Place selector lever in “P” position, and turn ignition switch ON (Do not start engine).
2. Make sure selector lever can be shifted to other than “P” position when brake pedal is depressed. Also
make sure selector lever can be shifted from “P” position only when brake pedal is depressed.
3. Move selector lever and check for excessive effort, sticking, noise or rattle.
4. Confirm selector lever stops at each position with the feel of engagement when it is moved through all the
positions. Check whether or not the actual position selector lever is in matches the position shown by the
shift position indicator and the transaxle.
5. The method of operating selector lever to individual positions
correctly should be as shown.
(A): Press selector button to operate selector lever, while
depressing the brake pedal.
(B): Press selector button to operate selector lever.
(C): Selector lever can be operated without pressing selector
button.
6. Confirm back-up lamps illuminate only when selector lever is
placed in “R” position. Confirm back-up lamps do not illuminate
when selector lever is in “P” or “N” position even if it is pushed
toward “R” position without pressing selector button.
7. Confirm engine can only be started with selector lever in “P” and “N” positions.
8. Make sure A/T is locked completely in “P” position.

BATTERY
Revision: June 20062007 Versa
CHARGING THE BATTERY
CAUTION:
Do not “quick charge” a fully discharged battery.
Keep the battery away from open flame while it is being charged.
When connecting the charger, connect the leads first, then turn on the charger. Do not turn on the
charger first, as this may cause a spark.
If battery electrolyte temperature rises above 55°C (131°F), stop charging. Always charge battery
at a temperature below 55°C (131°F).
Charging Rates
Do not charge at more than 50 ampere rate.
NOTE:
The ammeter reading on your battery charger will automatically decrease as the battery charges. This indi-
cates that the voltage of the battery is increasing normally as the state of charge improves. The charging amps
indicated above refer to initial charge rate.
If, after charging, the specific gravity of any two cells varies more than 0.050, the battery should be
replaced.
Trouble Diagnoses with Battery/Starting/Charging System TesterEKS00IAZ
CAUTION:
When working with batteries, always wear appropriate eye protection.
NOTE:
To ensure a complete and thorough diagnosis, the battery, starter and generator test segments must be
done as a set from start to finish.
If battery surface charge is detected while testing, the tester will prompt you to turn on the headlights to
remove the surface charge.
If necessary, the tester will prompt you to determine if the battery temperature is above or below 0°C
(32°F). Choose the appropriate selection by pressing the up or down arrow button, then press “ENTER” to
make the selection.
