Without Scan Tool

If a malfunction occurs, diagnosis system will identify the problem and ECU stores the codes for the trouble items.





At the same time, the system informs the driver of a malfunction via the "REAR ANTI-LOCK" warning light in the combination meter.





By turning on the ignition switch, the trouble can be identified by the number of blinks (diagnosis code) of the warning light.
In event of two codes, that having the smallest number (code) will be identified first.

HINT: The warning light does not show the diagnostic codes while the vehicle is running.

1. INSPECT BATTERY VOLTAGE
Inspect that the battery voltage is about 12 V.





2. CHECK THAT WARNING LIGHT TURNS ON
(a) Turn the ignition switch to ON.
(b) Check that the "REAR ANTI LOCK" warning light turns on for about 3 seconds.
If not, inspect and repair or replace the fuse, bulb and wire harness.

3. READ DIAGNOSTIC CODE
(a) Turn the ignition switch to ON.





(b) Using SST, connect the terminal Tc to E1 of the data link connector 1 (DLC1).
(c) Pull out the short pin from terminals WA and WB of the DLC1.
(d) In the event of a malfunction. 4 seconds later the warning light will begin to blink. Read the number of blinks.
(See: DIAGNOSTIC TROUBLE CODE DESCRIPTIONS)





HINT: The first number of blinks will equal the first digit of a two digit diagnostic code. After a 1.5 seconds pause, the 2nd number of blinks will equal the 2nd number of a two digit code. If there are two or more codes, there will be a 2.5 seconds pause between each, and indication will begin after 4.0 seconds pause from the smaller value and continue in order up to the the larger value.





(e) If the system is operating normally (no malfunction). the warning light will blink 2 times per second.
(f) Repair the malfunctioning parts.
(g) After the malfunctioning parts have been repaired clear the diagnostic codes stored in the ECU.
(See: HOW TO CLEAR DIAGNOSTIC TROUBLE CODES)

HINT: If you disconnect the battery cable while repairing, all diagnostic codes in the ECU will erased.

(h) Disconnect the terminal Tc from E1 of the DLC1.
(i) Install the short pin to terminals WA and WB of the DLC1.
(j) Turn the ignition switch to ON, and check that the REAR ANTILOCK' warning light goes off after the warning light goes on for about 3 seconds.
