P058A01 Auxiliary Battery Monitor Module General Electric Failure

P058A01 Toyota 

The voltage, current, and temperature of the battery are all detected by the battery status sensor assembly. The voltage and current are used to compute the charging condition, which is then sent to the ECM. Based on that signal, the ECM sends an order to the generator assembly to create voltage. The battery temperature is also estimated and sent to the ECM from the change in the resistance value of the thermistor incorporated into the battery status sensor assembly. When the battery is heated, the ECM limits the charging current and safeguards the battery based on this signal.

P1251 Toyota Hilux Turbocharger Electric Stepper Motor Failure

DTC P1251 Stepper Motor Toyota Hilux Vigo

P1251 Toyota Hilux 

P1251 is the most prevalent code for Hilux stepper problems. The codes are only a warning that you may have a problem with the Hilux turbocharger electric motor. This code, in the lack of further evidence, implies that the stepper motor has been changed. It’s also unusual for both the turbo and stepper motors to fail at the same time. Low boost with no evident physical signs is most likely due to a stepper motor malfunction. Any trouble codes that the ECU may have thrown should be investigated.

P0AA6 - Hybrid/EV Battery Voltage System Isolation Lost

P0AA6 DTC 

A high voltage isolation metre is included in the car. The high voltage isolation circuit’s function is to measure the resistance between the high voltage positive and negative direct current (DC) bus and chassis ground. When the ignition switches from ON to OFF and the high voltage contactor relays open, the battery energy control module performs this test. An internal isolation sensor in the battery energy control module detects the resistance between the high voltage DC positive and negative bus and chassis ground. This sensor circuit is subjected to an internal self-check by the battery energy control module. A low amplitude or compressed return signal indicates a lack of chassis ground resistance, and the hybrid powertrain control module 2 will indicate a loss of isolation.

P1737 Shift Motor Short to Ground

p1737 shift motor short to ground

DTC P1737

Shift Motor Short To Ground is the generic description for the P1737 OBD2 code. TCCU sets DTC P1737 if TCCU detects Shift Motor control circuit is open or short to ground.

The TCCU receives feedback from the shift motor through the position encoder. Four encoder switch signals offer information on the rotational direction and position of the shift motor. The TCCU supplies 5 volts to the MPS (Motor Position Sensor). The shift motor functions when the mode switch is changed, and the MPS contact point generates an ON/OFF signal. The TCCU checks the operation of the shift motor when it receives 5 volts.

P0139 HO2S S2 Slow Response

P0139

DTC P0139

This is a common Onboard Diagnostic-II code P0139 that indicates a voltage drop below in the O2 Sensor 2 Bank 1 circuit. During the deceleration cutoff point, the voltage should be at least 02 volts for at least seven seconds.
Essentially, the ECM (Engine Control Module) in your car is determining that the sensor’s reaction is too sluggish. This will start to set off the fault code, and the dreaded “check engine” light will appear on your dashboard.

Normal causes for the P0139 Code:

1.It’s possible that your vehicle’s fuel injection system has a leak, resulting in additional fuel being left in the exhaust system.
2.Faulty rear O2 sensor wiring. The wiring could simply be loose or worn.
3.Bad catalytic converter.

DTC C2304 Detecting Condition

Trouble Area

When the ignition switch was turned ON, or when the ECM determines whether it is an error of RAM in ECM or not, the ECM conducts a single communication. If any one of the following status occurs in the communication, the ECM conducts one more communication. While the ECM is conducting the communication, if (a) is duplicated 20 times continuously, or if (b) is duplicated 20 times continuously, or if (c) is duplicated 2 times continuously, the ECM outputs the OBD2 code P1670.

1. There was a communication error when receiving data.
2. Data sent from the injection pump correction unit does not match to the data received from the ECM.
3. Data received from the pump ROM is not input in the period of 1024 msecond.

Although the determining process is completed without a problem, the ECM conducts the communication again if an undefined code is found while checking an identification code of the receiving data. If the undefined code was duplicated 20 times in a row, the ECM outputs the DTC.
