Then the ECM compares the actual gear with the shift schedule in the ECM memory to detect mechanical CODE DTC DETECTION CONDITION TROUBLE AREA P0761 S3 stuck ON malfunction*1: When the ECM directs the gearshift to switch to 5th or 6th gear, the engine overruns (clutch slips). The ECM determines there is a malfunction when either (a) When the ECM directs the transmission to switch to 4th gear, the actual gear is shifted to 3rd. (b) When the ECM directs the transmission to switch to 5th gear, the engine overruns (clutch slips). Shift solenoid valve S3 remains closed Shift solenoid valve SLT remains closed Valve body is blocked Automatic transmission (clutch, brake or gear, etc.) P0761 S3 stuck OFF malfunction*2: Shifting to 1st, 2nd, and 3rd gears is impossible. The ECM determines there is a malfunction when the following conditions are both met. (2-trip detection logic) (a) When the ECM directs the transmission to switch to 2nd gear, the actual gear is shifted to 4th. (b) When the ECM directs the transmission to switch to 6th gear, the actual gear is shifted to 6th. Shift solenoid valve S3 remains open Valve body is blocked Automatic transmission (clutch, brake or gear, etc.) HINT: 1st 2nd 3rd 4th 5th 6th *1: Actual gear position under S3 stuck ON malfunction 1st 2nd 3rd 3rd N* N* *2: Actual gear position under S3 stuck OFF malfunction 3rd 4th 4th 4th 5th 6th N*: Neutral Gear position during fail-safe operation: AB60E AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMIS... |
