applied.
●Selector lever can be moved from “P” position with key in ON position and brake pedal released.
●Selector lever can be moved from “P” position when key is removed from key cylinder.
SYMPTOM 2:
●Ignition key cannot be removed when selector lever is set to “P” position.
●Ignition key can be removed when selector lever is set to any position except “P”.
1. CHECK KEY INTERLOCK CABLE
Check key interlock cable for damage.
OK or NG
OK >> GO TO 2.
NG >> Repair key interlock cable. Refer to AT- 4 1 2 , "
KEY INTERLOCK CABLE" .
2. CHECK SELECTOR LEVER POSITION
Check selector lever position for damage.
OK or NG
OK >> GO TO 3.
NG >> Check selector lever. Refer to AT- 4 1 6 , "
Park/Neutral Position (PNP) Switch Adjustment" .
3. CHECK POWER SOURCE
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Check voltage between A/T device harness connector M58 ter-
minal 5 (G) and ground.
OK or NG
OK >> GO TO 5.
NG >> GO TO 4.
4. DETECT MALFUNCTIONING ITEM
Check the following items:
1. Harness for short or open between ignition switch and A/T device harness terminal 5
2. Fuse
3. Ignition switch (Refer to PG-2, "
POWER SUPPLY ROUTING" .)
OK or NG
OK >> GO TO 5.
NG >> Repair or replace damaged parts.Voltage: Battery voltage

TROUBLE DIAGNOSIS
10. After repairing the malfunction, touch “SELF-DIAG [CURRENT]”
to check that “No DTC IS DETECTED” is displayed.
●After checking the display, touch “ERASE”.
●If any malfunction is displayed on “SELF-DIAG [CURRENT],
repair or replace the malfunctioning again.
11. Touch “BACK” key of CONSULT-II to “SELECT SYSTEM”
screen. Touch “SELF-DIAG [PAST].
12. Check that no malfunction is detected on “SELF-DIAG [PAST].
●If any malfunction is deployed, Touch “ERASE” in the “SELF-
DIAG [CURRENT]” screen, and check the display.
13. Turn ignition switch OFF, then turn off and disconnect CONSULT - I I .
14. Turn ignition switch ON, and check the system with the SRS air bag warning lamp (User mode).
15. Check that no malfunction is detected. Now the diagnosis is complete.
DIAGNOSTIC PROCEDURE 3
Inspecting SRS Malfunctioning Record
If any malfunction is detected in "SRS Operation Check", but no malfunction is detected in “SELF-DIAG [CUR-
RENT]” on CONSULT-II, carry out the following steps.
1. CHECK BATTERY VOLTAGE
Disconnect both battery cables and check that the battery voltage is 9 V or more.
OK or NG
OK >> GO TO 2.
NG >> Charge the battery.
2. CONSIDER POSSIBILITY OF NOT ERASING SELF-DIAGNOSTIC RESULT AFTER REPAIRING.
Is it the first time for maintenance of SRS?
YES or NO
YES >> GO TO 3.
NO >> Erase the self-diagnostic results, and Check the "SRS Operation Check". Refer to SRS-16, "
SRS
Operation Check"
3. CHECK "SELF-DIAG [PAST]" BY CONSULT-II
Store the memory in "SELF-DIAG [PAST]"
YES or NO
YES >> Repair the part of "SELF-DIAG[PAST]"
NO >> Check the "TROUBLE DIAG RECORD", and then repair it. Refer to SRS-21, "
DIAGNOSTIC
CODE CHART"
