Preliminary Information
PIT5771A Wobble Vibration On Hard Acceleration
Models
| Brand: | Model: | Model Years: | VIN: | Engine: | Transmissions: | |
| from | to | |||||
| Chevrolet | Equinox | 2020 | All | All | LYX | All |
| GMC | Terrain | 2020 | All | All | LYX | All |
| Involved Region or Country: | North America |
| Additional RPO/s: | LYX, SAL or SPM |
| Condition: | Wobble / Vibration the customer will typically state this occurs on hard acceleration, 30 to 70 MPH. (WOT) |
| Cause: | Possible drive line vibration, information needed. |
IMPORTANT: This PI is to address the above scenario ONLY.
If able to duplicate the concern, record the event using the Pico Scope with the CH-51450TA246 Triple Axis Sensor. If the Pico reading at the above mentioned speeds is T1 lateral above 40 mg or above 30 mg with 10 mg of T3 lateral, return the vehicle to the customer advising them there will be a bulletin released and a field fix for this concern early in the first quarter of 2021. If this is NOT the disturbance noted in the file review perform normal NVH diagnostics.

KAWISH OBD2 Breakout Box Auto OBDII Protocol Detector 16-Pin CAN Bus Test Breakout Box with LCD Display for OBDII Protocol Communication Detection/ECU Tool
- 【Auto OBD2 Breakout Box】 This is an Breakout Box OBDII Protocol Detector for the car OBDII diagnostic link connector, which provides easy access to the OBDII connector so that after connecting the automotive OBDII system, the different color LEDs on the OBD2 junction box can monitor the protocol, power and ground signals conveniently and safely, good helps detect if the problem is with the vehicle's ECU or decoder.
- 【LED flashing of OBDII Breakout Box】 LEDs provide a quick indication of OBDII Protocol Detect power or ground issues. When the code reader is communicating with the vehicle, the yellow LED (pin 2/6/7/10/14/15) lights up with a signal waveform. If a normal car ground is detected, the green LED (pin 4/5) will be on solid. If it is detected that the car power supply is normal, the red LED (Pin16) will be always on.
- 【Digital display and 16-pin interface design】 Auto 16 pin dlc breakout box an LED display design is added to first eliminate the voltage problem of the OBD port and easily determine whether the cable and the car OBD port are connected correctly. The port is designed with a 16-pin interface, when the OBD2 scanner communicates with the vehicle, it can easily connect all 16 pins of the OBDII junction box for more tests quickly and intuitively.
- 【4mm banana plug & 128cm extension cord】 The OTC Can test box has a safety banana socket that accepts all types of 4mm banana plugs. You can connect a multimeter or oscilloscope to the banana socket to detect the detailed signal information of the corresponding lit port. The cable length of the obd ii breakout testing box is 128cm, which makes device connection more convenient and you don't have to operate in a narrow space in the car.
