Diagnostic Trouble Code (DTC) Information ECM-P157282

Condition 

The control module is continuously supplied with information about the position and status of the brake pedal switch from the brake control module (BCM) via CAN communication.

The control module checks the communication with the Brake control module (BCM).

The diagnostic trouble code (DTC) is stored if the control module detects that:

• Information from Brake control module (BCM) is incorrect/unreasonable.

The control module's test for the diagnostic trouble code (DTC) starts in the event of:

• Ignition switch position II.

HINT: If Engine control module (ECM) has been recharged or if the battery voltage has been interrupted, the brake pedal must be pressed down twice for approx. two seconds to activate the cruise control function. 

Substitute Value 

• Cruise control is disengaged when the fault is active.

Possible Source 

• Open-circuit in the communication cable.
• Short-circuit to ground in the communication cable.
• Short-circuit to supply voltage in the communication cable.
• Contact resistance or oxidation in the terminals.
• Open-circuit in terminals.
• Short-circuit in connections.

Fault symptom[s] 

• Cruise control/Does not engage
