DIAGNOSTIC CODES Code No. | Light Pattern | Diagnosis System — | ∩∩∩∩∩∩∩∩∩∩∩∩∩_ | Normal 42 | ∩∩∩∩_∩∩_ | Defective No. 1 speed sensor (in combination meter) — severed wire harness or short circuit 61 | ∩∩∩∩∩∩∩_∩ | Defective No. 2 speed sensor (in ATM) — severed wire harness or short circuit 62 | ∩∩∩∩∩∩_∩∩_ | Severed No. 1 solenoid or short circuit — severed wire harness or short circuit 63 | ∩∩∩∩∩∩_∩∩∩_ | Severed No. 2 solenoid or short circuit — severed wire harness or short circuit 64 | ∩∩∩∩∩∩_∩∩∩∩_ | Severed lock-up solenoid or short circuit — severed wire harness or short circuit AT2000 HINT: If codes 62, 63 or 64 appear, there is an electrical malfunction in the solenoid. Causes due to mechanical failure, such as a stuck valve, 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 by removing the fuse DOME (20A) 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. HINT: • Cancellation can be also done by removing the battery negative (—) terminal, but in this case other memory systems (TCCS diagnosis memory, etc.) will be also canceled out. • The diagnostic code can be also 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 to confirm that a "normal code" is now read on the O/D OFF light. [THIS IS FIGURE: Diagram showing DOME fuse location in fuse box, labeled AT1883] Front
