Electronic Control System Troubleshooting

TROUBLESHOOTING OF ELECTRONIC CONTROL SYSTEM

NOTE:
- If diagnostic code Nos. 42, 61, 62 or 63 occur, the overdrive indicator light will begin to blink Immediately to warn the driver. However, an impact or shock may cause the blinking to stop; but, the code will still be retained in the Electronic Controlled Transaxle (ECT) computer memory until canceled out.
- There is no warning for diagnostic code No. 64.
- In the event of a simultaneous malfunction of both No. 1 and No. 2 speed sensors, no diagnostic code will appear and the fail-safe system will not function. However, when driving in the D range, the transmission will not up-shift from first gear, regardless of the vehicle speed.
