Circuit Description

The powertrain interface module (PIM) is configured for either a manual or automatic transmission vehicle. If the PIM is configured for manual transmission and it receives any messages on the GM LAN which originate from the transmission control module (TCM), DTC B1019 sets.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC B1019 ROM Configuration Mismatch

Conditions for Running the DTC

Conditions for running the DTC are:

    • The ignition is switched ON.
    • The ignition voltage is 10-16 V.
    • The vehicle is fitted with an automatic transmission.

Conditions for Setting the DTC

The PIM is configured for manual transmission and receives a message from the TCM via the GM LAN bus.

Action Taken When the DTC Sets

A check powertrain message is displayed on the instrument cluster multi-function display.

Conditions for Clearing the DTC

Refer to Diagnostic General Descriptions for information on the conditions for clearing DTCs.

Diagnostic Aids

Refer to Cruise Control Description and Operation for cruise control switch description, operation and inspection procedures. Refer to Cruise Control Schematics , Cruise Control Component Views , and Cruise Control Connector End Views . Refer to Testing for Intermittent Conditions and Poor Connections for intermittent fault conditions

Test Description
