Condition




Lock-up solenoid SL controls the transmission lock-up function. Solenoid SL operates when it receives battery voltage from the transmission control module (TCM) and is activated under different driving conditions depending on road speed, throttle position and the driving mode selected. Diagnostic trouble code (DTC) AT-332 is stored if the transmission control module (TCM) registers an open-circuit in the solenoid SL circuit when the solenoid should not be activated. Solenoid SL cannot then be activated.
Diagnostic trouble code (DTC) AT-332 is also stored if the transmission control module (TCM) registers a short-circuit in the solenoid SL amplifier when this should not be activated. Solenoid SL cannot then be activated.

Substitute value
The transmission control module (TCM) "Emergency mode I" program has been initiated.

Possible source
- Open-circuit in signal cable
- Defective solenoid.
- Open-circuit in power ground.
- Contact resistance in terminals
- Defective control module.

Fault symptom[s]
- The combined instrument panel warning lamp flashes. *)

Note! The Motronic 4.4 engine control module (ECM) stores a diagnostic trouble code (DTC) when the transmission sends a malfunction indicator lamp (MIL) request. Erase this diagnostic trouble code (DTC) in the Motronic engine control module (ECM) when the transmission fault has been repaired.

*) Applies only to USA/CDN 1997 model year-
- No lock-up function.
- No adaptation of the gear slippage times at high altitude (High Altitude Compensation).
