How to Perform Self-Diagnosis

CONSULT INSPECTION PROCEDURE

1. Turn ignition switch "OFF".
2. Connect "CONSULT" to the data link connector.

3. Turn ignition switch "ON".
4. Touch "START".

5. Touch "IVMS".

6. Touch "AUTO DRIVE POSITIONER".

- DATA MONITOR, ACTIVE TEST and SELF-DIAGNOSIS are available for the automatic drive positioner.

HOW TO PERFORM SELF-DIAGNOSIS

1. Choose "AUTO DRIVE POSITIONER" in SELECT TEST ITEM.
2. Touch "SELF-DIAG RESULTS" of SELECT DIAG mode.
3. Touch "START".

4. Seats and steering automatically move, and self-diagnosis will start.
5. Within 15 seconds after seat and steering come to a stop, drive the vehicle at speeds greater than 7 km/h (4 mph) to diagnose the vehicle speed sensor.
6. After completing self-diagnosis, diagnostic results appear on the display.

- When no malfunction is detected.

- When malfunction is detected
A summary of diagnostic results is given in the following chart.

7. Erase the diagnostic results memory.
a. Turn ignition switch "ON".
b. Touch "IVMS".
c. Touch "AUTO DRIVE POSITIONER".
d. Touch "SELF-DIAG RESULTS".
e. Touch "START".
f. Touch "ERASE".

On-board Diagnosis - Mode V (Automatic drive positioner operation)

HOW TO PERFORM V

MALFUNCTION CODE TABLE
In this mode, a malfunction code is indicated by the number of flashes from the automatic drive positioner indicator lamps (indicator lamp 1 - indicator lamp 2) as shown above.

WORK FLOW

NOTE:
- When LCU connectors are disconnected for more than 1 minute such as during trouble diagnoses the "disconnected" data will be memorized by the BCM Body Control Module. (While BCM memorizes the "disconnected" data, IVMS communication diagnosis of CONSULT will display "PAST NO RESPONSE".) Therefore, after reconnecting the LCU connectors, erase the memory
- To erase the memory perform the procedure below.
Erase the memory with CONSULT or turn the Ignition switch to "OFF" position and remove 7.5 A fuse [No. [14], located in the fuse block (J/B)].

Preliminary Check
After performing preliminary check, go to symptom chart.

Symptom Chart
Symptom numbers in the symptom chart correspond with those of preliminary check.

DIAGNOSTIC PROCEDURE 1 (Power supply and ground circuit for LCU05)

Power supply circuit check
Check voltage between LCU05 terminal (16) and ground.
If NG, check the following.
- Circuit breaker-2
- Harness for open or short between circuit breaker-2 and LCU05.

Ground circuit check
Check continuity between LCU05 terminal (14) and ground.

DIAGNOSTIC PROCEDURE 2 (Power supply and ground circuit for tilt/telescopic motor)

Power supply circuit check
Check voltage between BCM terminal (104) and ground.
If NG, check the following.
- Circuit breaker-2
- Harness for open or short between circuit breaker-2 and BCM
