DTC 82

DTC 82

1-2 SHIFT SOLENOID CIRCUIT FAULT

Circuit Description:

Ignition voltage is supplied directly to the 1-2 shift solenoid. The Powertrain Control Module (PCM) controls the solenoid by providing the ground path through CKT 1222.

DTC 82 Will Set When:

The PCM commands the solenoid "ON" and voltage remains high for 2 seconds. The PCM commands the solenoid "OFF" and voltage remains low for 2 seconds.

Action Taken (PCM will default to):

The transmission will only allow second and third gear, or first and fourth gear. DTC 82 will be stored in the PCM memory but will not turn "ON" the MIL (Malfunction Indicator Lamp).

DTC 82 Will Clear When:

The fault condition(s) no longer exist, and the ignition switch is cycled "OFF" then "ON."

DTC Chart Test Description:

Number(s) below refer circled number(s) on the diagnostic chart.

If the voltage remains high for at least 2 seconds, DTC 82 will set. If the voltage drops for more than 2 seconds, DTC 82 will set.

1. This test checks the function of the 1-2 shift solenoid and the internal transmission wiring harness.
2. This test checks for power to 1-2 shift solenoid from the ignition through the fuse.

Diagnostic Aids:

Check all connections for the transmission.

Refer to "PCM Intermittent Diagnostic Trouble Codes or Performance."

An open in the ignition feed circuit can cause multiple DTC(s) to set.
