Analysis of China GM p 1689 Automobile Fault Code

1, the fault code applies to models: GM, Buick, Chevrolet, Cadillac, Hummer and Jinbei.

Fault code: P 1689

English meaning: Driving anti-skid traction control (TCS) system, transmitting torque signal-failure English meaning: Traction control system (TCS), transmitting torque signal-failure category: power system (manufacturer's own meaning) Detailed meaning: The function of driving anti-skid traction control (TCS) system is to control torque output by delaying ignition time, shift up in advance, start in the second gear, prevent the torque converter from locking, and brake to prevent slipping. The fault causes include output torque circuit fault, electronic brake traction control module (EBTCM) fault and electronic control module (PCM or ECM) fault.

2. Fault code applicable model: mini

Fault code: P 1689

Electronic throttle system, monitoring level 2/3- incorrect engine torque

English meaning: Electronic throttle system, monitor level 2/3-incorrect engine torque Category: Power system (manufacturer's own meaning) Detailed meaning: In the electronic throttle (ETC) system, the electronic control module (ECU) instructs the throttle position motor to optimize the throttle opening according to the signal of the accelerator pedal position (APP) sensor, engine speed, vehicle speed and air conditioning energy consumption.

3. Fault code applicable model: BMW

Fault code: P 1689 English meaning: engine control module (ECM) self-test-unbelievable torque request.

English meaning: ECM self-test-simple torque request category: powertrain system (manufacturer's own meaning) Detailed meaning: engine control module, also called engine control unit (in some cars, engine control module and transmission control module are integrated to form powertrain control module), which controls the operation of the whole engine. Its main function is to control the optimal fuel injection quantity and ignition timing of the engine. Another important role is the component responsible for monitoring exhaust emission control. 4.
