B000A — Park Switch – Shift Lever Position Not Plausible

System: Body  |  Type: Generic (OBD-II Standard)  |  Make: Holden

About B000A

B000A is a generic (obd-ii standard) body diagnostic trouble code recorded for Holden vehicles. It belongs to the B-prefix family of codes, which covers body, interior, airbag, or comfort-electronics faults.

Scanning & clearing: Body (B) codes are often stored in the body control module, airbag module, or climate module. A basic OBD-II tool usually will not read body codes — an enhanced or OEM-level scan tool is typically required.

Because B000A is a generic OBD-II code, its base definition is shared across manufacturers. The specific diagnostic steps, reference values, and repair procedures can vary by vehicle, and the TaT Diagnostic Assistant includes verified procedures submitted by working technicians.

Code Information

The Body Control Module (BCM) and/or Transmission Control Module (TCM) continuously monitor the park switch and gear selector position inputs to confirm that the reported shift lever position is logical and consistent with vehicle operating conditions. DTC B000A is set when the control module detects an implausible or contradictory signal from the park switch, such as the switch indicating PARK while other inputs (gear position sensors, range data, or vehicle movement status) indicate a different state. This fault is typically logged when the signal falls outside calibrated plausibility limits...
