Definition:
Power Supply (B+) Terminal 15 Low Voltage
Description:
Ignition on, the ECM detected a low voltage condition on the power supply terminal (15). To achieve optimal anti-theft protection for the vehicle, an anti-theft immobilizer is installed. The anti-theft immobilizer is a system for enabling and locking the Engine Control Module (ECM). So that this system cannot be circumvented, it is necessary to perform adaptation of the anti-theft immobilizer using the Vehicle Diagnostic and Information System VAS 5052 in the On Board Diagnostic (OBD) function. The great availability of equipment options makes it necessary to adapt the Engine Control Module (ECM) to the vehicle (e. g. throttle valve control module or cruise control system). This “writing” function is not possible with the generic scan tool.
Cause:
(If ECM was replaced) ECM ID not the same as the replaced unit
ECM has failed
Voltage supply for Engine Control Module (ECM) has shorted - ยานยนต์และพาหนะ
