Diagnostic trouble code (DTC) information

Condition

Fig 1: Identifying Control Module

Courtesy of VOLVO CARS OF NORTH AMERICA.

The solenoids are controlled by power stages in the transmission control module (TCM). The transmission control module (TCM) opens the power stages to activate the solenoids and sends a voltage through the circuit. Diagnostic trouble code (DTC) TCM-0060 is stored if the control module registers an internal fault in the power stage circuit for solenoids S1, S2, S3, S4 or S5.

Substitute Value

The transmission control module (TCM) Emergency mode III program has been initiated.

Possible Source

Internal fault in the control module.

Fault symptom[s]

Warning lamp for the automatic transmission flashes
Malfunction indicator lamp (MIL) lit
No lock-up function
Harsh gear shifting
No shifting.

HINT: Harsh gear shifting can be caused by:

no reduction of line pressure when shifting
no reduction of line pressure when moving the gear selector between positions P-R, N-R and N-D
no torque limiting request to the engine control module (ECM) when shifting.

HINT:

HINT: No shifting - because the transmission control module (TCM) prevents activation of the solenoids. This stops gear-shifting.
