BORFA C2100H

PCM P1571H

does anybody know what these codes are
thanks for any help!!!

BO-RFA C2100H Remote Function Actuation, Left Front Sensor Malfunction-TPM

10-PCM P1571H Powertrain Control Module, ASR Desired Torque-C

AO-LDCM B2264H Left Door Control Module, Vertical Position Sensor Fault DCM-L

 

Circuit Description
When the TPM sensors detect a vehicle speed of 16-24 km/h (10-15 mph), the TPM sensors will enter a powered up stage and begin to transmit a unique identification code and tire pressure information from 0-437 kPa (0-62 psi) to the receiver. The receiver waits for the first sensor to transmit information. When the first sensor transmits its information 15 times, the receiver checks whether all sensors have sent their information. If one or more sensors do not transmit information, the receiver will set the appropriate DTCs for the TPM sensor that did not transmit. When the vehicle has been stationary for more than 1 minute, the sensor will enter a power down or sleep mode and will stop transmitting tire pressure information.

Conditions for Setting the DTC
The vehicle completes a diagnostic cycle (driving for about 20 minutes at speeds over 24 km/h [15 mph]) and the left front TPM sensor has not transmitted tire pressure information.
The receiver has received at least one TPM sensor transmit tire pressure information 15 times and no tire pressure information was received from the left front TPM sensor.
Action Taken When the DTC Sets
Stores a DTC C2100 in the receiver memory
Sends a message to the IPC to display the SERVICE TIRE WARN SYS message
The IPC will default to display the left front tire pressure as XXX kPa (XX psi).
Conditions for Clearing the DTC
The left front TPM sensor transmits tire pressure information to the receiver before a diagnostic cycle is completed.
A history DTC will clear after 50 consecutive ignition cycles if the condition for the malfunction is no longer present.
Use the IPC clearing DTCs feature.
Use a scan tool.
Diagnostic Aids
The IPC will default to display the left front tire pressure as XXX kPa (XX psi) if the receiver is unable to receive or send tire pressure data.
If there is an open in the serial data line to the receiver, the IPC will display XXX kPa (XX psi) for all tire pressure values and the SERVICE TIRE WARN SYS message.
Clear the receiver diagnostic memory before road testing the vehicle whenever a TPM sensor is replaced in order to avoid reading the original DTC stored in the memory.
Take tire pressure measurements when the tires are cold in order to obtain the lowest readings.

Circuit Description
The PCM supplies 5.0 volts on the Desired Torque circuit to the Electronic Brake and Traction Control Module (EBTCM). The EBTCM toggles this 5.0 volt signal to a ground in order to produce a duty cycle signal. The signal is proportional to the amount of engine output torque reduction requested by the EBTCM. The EBTCM supplies this signal when it detects a wheel slip. In order to reduce engine output torque, the PCM reduces the amount of spark advance and in some cases the PCM disables a number of fuel injectors. This diagnostic test checks for a Desired Torque signal failure. If the PCM does not receive the Desired torque signal this DTC sets.

Conditions for Setting the DTC
The traction control has not failed.
The engine speed is greater than 500 RPM for 20 seconds.
The desired torque signal is not received by the PCM for 3 seconds.
Action Taken When the DTC Sets
The powertrain control module (PCM) stores the DTC information into memory when the diagnostic runs and fails.
The malfunction indicator lamp (MIL) will not illuminate.
The PCM records the operating conditions at the time the diagnostic fails. The PCM stores this information in the Failure Records.
Conditions for Clearing the MIL/DTC
A last test failed, or the current DTC, clears when the diagnostic runs and does not fail.
A history DTC clears after 40 consecutive warm-up cycles, if failures are not reported by this or any other emission related diagnostic.
Use a scan tool in order to clear the MIL/DTC.
Diagnostic Aids

Important
Do not perform this diagnostic procedure if the concern is not related to the ABS and/or the Traction Control system(s).


The following may cause an intermittent:

Mis-routed harness
Rubbed through wire insulation
Broken wire inside the insulation


The code indicates to disconnect power to left mirror connector C2. Measure the voltage between the left power mirror connector C2 terminal B and ground. (3.5-5.5V). If in range replace power mirror. If not, check for an open, a short to ground, or a short to battery in CKT 784.

If OK, replace the left Door Control Module (DCM).

don&kewlbrz i change the battery and the car is all wacked out today i check the codes again i must have 10 more i don't know whats going on.car was fine i changed the oil and put a new belt and a new agm gel battery. :banghead:
thanks for your help :confused: :confused:

ps i am trying to get the car into the dealer

before running to the dealer. disconnect your battery overnight and reconnect in the morning and check for codes. If you have a few codes, record them, delete them using the DIC, then drive around and see if they reoccur.

Thanks for the great information with explanation. I have the same condition with 2 other error codes, 28 TCS C1255 H and 28 TCS C1281 H, after installing a K&N Cold flow filter. It seems that I lost some performance. Thanks for the info

well took the car to the dealer it needs a wheel sensor.but they can'''t find any reason for the the long cranking.the tech told me to change the gas filter
because the car needs 55 psi of fuel pressure to start says he cleared all codes and drove it and no codes came back.i am still :confused: why i had all those codes and why the car is cranking so long.
