HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate. In
general, each customer feels differently about a problem. It is important to fully understand the symptoms or
conditions for a customer complaint.
Make good use of the two sheets provided, “INFORMATION FROM CUSTOMER” (AT- 2 8 0 , "
Information from
Customer") and “DIAGNOSTIC WORKSHEET” (AT-281, "Diagnostic Worksheet"), to perform the best trou-
bleshooting possible.
5.oFor self-diagnosis NG items, inspect each component. Repair or replace the damaged parts.AT-273,

6.oPerform all ROAD TEST and re-mark required procedures.AT-291,

7.oPerform the Diagnostic Procedures for all remaining items marked NG. Repair or replace the damaged parts.
Refer to the Symptom Chart when you perform the procedures. (The chart also shows some other possible
symptoms and the component inspection orders.)AT-308,

SELF-DIAGNOSIS CODE CONFIRMATION PROCEDURE
After the repair, perform the following procedure to confirm the malfunction is eliminated.
With CONSULT-II
1. Start engine.
2. Select “SELF-DIAG RESULTS” mode for A/T with CONSULT-II.
3. Drive vehicle under the following conditions:
Selector lever in “D” position, vehicle speed higher than 30 km/h
(19 MPH), throttle opening greater than 1/8 of the full throttle
position and driving for more than 5 seconds.
Without CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions:
Selector lever in “D” position, vehicle speed higher than 30 km/h
(19 MPH), throttle opening greater than 1/8 of the full throttle
position and driving for more than 5 seconds.
3. Perform self-diagnosis.

DescriptionECS004TM
The vehicle speed sensor·MTR is built into the speedometer assem-
bly. The sensor functions as an auxiliary device to the revolution sen-
sor when it is malfunctioning. The TCM will then use a signal sent
from the vehicle speed sensor·MTR.
