P161009 | Control Module Processor (Brake Override System Input Signal) Component Failure |
Any of the following conditions are met (1 trip detection logic).
| ECM |
Does not come on |

MONITOR DESCRIPTION
The ECM compares input signal information for brake override system control calculations for control and monitoring. If the ECM determines a malfunction mode in which brake override system operation conditions are not met, a DTC is stored to indicate the brake override system malfunction.

HINT:
Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
PROCEDURE
1. |
CLEAR DTC |
(a) Clear the DTCs.
Powertrain > Engine > Clear DTCs(b) Turn the ignition switch off and wait for at least 30 seconds.
|
2. |
READ OUTPUT DTC (DTC P161009) |
(a) Drive the vehicle in accordance with the driving pattern described in Confirmation Driving Pattern.
(b) Read the DTCs.
Powertrain > Engine > Trouble Codes
