- System
- ECT A245E/A246E
- Dashboard light
- Malfunction indicator lamp (Check Engine)
- Check-engine blink code
- 63
- Applies to
- 4-speed A/T A245E/A246E (RM821E ECT section covers both). PK: ZZE121R-GEPNKP 1.6 auto = A246E 30500-1A761 (PartSouq EPC fig 3501). PK 1.3 NZE120 has no auto.
- Description
- S2 SOLENOID VALVE ELECTRICAL MALFUNCTION
- Detection / symptoms
- Detection: (a) Solenoid resistance is 8 W or less (short circuit) when the solenoid is energized. (b) Solenoid resistance is 100 kW or more (open circuit) when the solenoid is not energized. (b) Fail safe function: If either of the solenoid valve circuits develops an open or short, the En noid valve ON and OFF to shift to the gear positions shown in the table ab turns the ST solenoid valve OFF at the same time. If both solenoids malfun not be performed electronically and must be done manually. Manual shifting as shown in the above table must be done (In the case of a ECU stops sending current to the short circuited solenoid).
- Possible causes
- Transmission wire; Wire harness; S1/S2 solenoid valve; Engine ECU gine ECU turns the other sole- ove. The Engine ECU also ction, hydraulic control can- short circuit, the Engine
- What to check
- Workshop check order (RM821E): CHECK TRANSMISSION WIRE(ECU − Body ground) -> CHECK WIRE HARNESS AND CONNECTOR(Transmission wire − ECU) -> INSPECT TRANSMISSION 2WAY NO.1 SOLENOID ASSY(S1) -> INSPECT TRANSMISSION 2WAY NO.2 SOLENOID ASSY(S2)
