DTC 81 Right Front Solenoid Circuit Shorted To Battery:

Circuit Description:
This DTC identifies a solenoid that cannot be energized due to an short to voltage in its driver circuitry. These malfunctions can affect ABS operation since the flow of brake fluid to the wheel cylinder cannot be stopped, making ABS operation for that channel impossible.

DTC Will Set When:
DTC 81 can be set only when the solenoid is commanded "ON." If the EBCM detects the right front solenoid control circuit voltage is out of specification, a malfunction exists.

Action Taken:
A malfunction DTC is stored, ABS is disabled. The amber ABS warning lamp is turned "ON."

DTC Chart Test Description:
Number(s) below refer to circled number(s) on the diagnostic chart.
1. Checks for a solenoid that is internally shorted to voltage.
2. Checks for a solenoid that is not within proper resistance values.
3. Indicates if a short to voltage exists in the solenoid control circuitry.
4. Checks for a possible intermittent malfunction in the solenoid circuitry due to poor terminal contact.

Diagnostic Aids:
An intermittent malfunction may be caused by a poor connection, rubbed through wire insulation, or a wire that is broken inside the insulation.

The frequency of the malfunction can be checked by using the enhanced diagnostic function of the Tech 1.

Any circuitry that is suspected of causing the intermittent complaint should be thoroughly checked for backed out terminals, improper mating, broken locks, improperly formed or damaged terminals, poor terminal to wiring connections or physical damage to the wiring harness.
