(b) In event of a malfunction, the light will blink once every 0.5 seconds. 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 diagnostic code. If there are two or more codes, there will be a 2.5 seconds pause between each.

NOTE: In event of a number of trouble codes, indication will begin from the smaller value and continue in order to the larger.

NOTE: If codes 62, 63 or 64 appear, there is an electrical malfunction with the solenoid. Causes due to mechanical failure such as a stuck switch will not appear.

CANCEL OUT DIAGNOSTIC CODE

1. After repair of the trouble area, the diagnostic code retained in memory by the ECT ECU must be canceled out by removing the fuse ECU +B (15A) for 10 seconds or more depending on ambient temperature {the lower the temperature, the longer the fuse must be left out) with the ignition switch off.

NOTE:

• Cancellation can also be done by removing the battery negative ( —) terminal, but in this case other memory systems (clock, radio ETR, etc.) will also be canceled out.

• The diagnostic code can also be canceled out by disconnecting the ECT ECU connector.

• If the diagnostic code is not canceled out, it will be retained by the ECT ECU and appear along with a new code in event of future trouble.

2. After cancellation, perform a road test, if necessary, to confirm that a "normal code" is now read on the OD OFF light.
