Check transmission wire.
PREPARATION:

Disconnect the transmission wire connector.

CHECK:

Measure resistance between S2 of transmission wire connector and body ground.

OK:
1. Resistance: 11 to 15 Ω at 20°C (68°F)
1. NG: Go to 3
2. OK: Go to next step
Measure resistance between terminal S2 of ECM connector and body ground.
PREPARATION:
