P1703Gearbox computer: engine data flagged as faulty

• Suzuki code · Transmission

How the car detects it

The gearbox computer receives engine data over the CAN network (throttle, coolant temperature, engine speed, torque). The engine computer has marked some of it as faulty, so the gearbox limits how it shifts. The cause is an engine fault: read the engine computer's codes first.

What you may notice

• No 4th gear or no torque-converter lock-up

Likely causes

• LikelyA fault stored in the engine computer
