Diagnostic Trouble Code (DTC) Information

Shift solenoids S1, S2, S3, S4 and S5 operate together to control gear-shifting. The solenoids are controlled by power stages in the transmission control module (TCM). The control module activates the power stages to activate the solenoids and sends voltage through the circuit. The control module checks the function of the circuit by sending out a control current when the solenoid is not activated.

Diagnostic trouble code (DTC) TCM-0002, TCM-0008, TCM-0102, TCM-0108 or TCM-010B is stored if the transmission control module (TCM) registers that the signal in the circuit for solenoid S1, S2, S3, S4 or S5 is missing when the solenoid is not activated. Which diagnostic trouble code (DTC) is stored depends on which circuit is faulty.

The diagnostic trouble code (DTC) can be diagnosed when the ignition is switched on.

Substitute Value

For diagnostic trouble codes (DTCs) TCM-0002, TCM-0008, TCM-0108 and TCM-010B

Emergency program Emergency mode 1 in the transmission control module (TCM) has been initiated.

For diagnostic trouble code (DTC) TCM-0102

Emergency program Emergency mode 2 in the transmission control module (TCM) has been initiated.

HINT: EMERGENCY MODE IN THE EVENT OF A FAULT

Possible Source

Short-circuit to supply voltage in the signal cable
Internal fault in the transmission control module (TCM).

Fault symptom[s]
