When Monitored and Set Condition
When Monitored: Engine speed greater than 450 rpm, no engine speed DTCs, no TCM under-voltage system operation, no output speed sensor DTCs (signal from the ABS system), all wheel speeds above 250 rpm (signal from the ABS system), no rear wheel speed DTCs (signal from the ABS system), and no wheel slip detected (signal from the ABS system), no shifting operation, N3 input speed sensor greater than 800 rpm and N2 input speed sensor greater than 0 rpm and the TCM not in reset.
Set Condition: If the speed difference between the N2 and N3 input speed sensors is greater than 150 rpm.
POSSIBLE CAUSES
- SPEED SENSOR DTCS PRESENT
- INTERMITTENT WIRING AND CONNECTORS
- INTERNAL TRANSMISSION
- TCM - INPUT SPEED SENSOR MISMATCH
