The instrument panel module (IPM) is the power mode master and the remote control door lock receiver (RCDLR) is the backup power mode master. Both modules receive information regarding ignition mode switch position from the ignition mode switch. IPM receives ignition mode switch position data through the IPM ignition mode data signal circuit.
This diagnostic procedure supports the following DTC:
DTC B1380 Device Ignition ACCESSORY Circuit
This vehicle has DTCs which include DTC Symptoms. For more information on DTC Symptoms, refer to DTC Symptom Description .
DTC Symptom | DTC Symptom Descriptor |

59 | Component Protection Time-Out |
Voltage supplied to the module is in the normal operating voltage range of 9-16 volts.
The IPM sets the code if it detects that the OFF/ACC contact of the ignition mode switch is closed for more than 30 seconds.
The IPM does not react to switch inputs of equal or lower priority until condition is cleared.
• | A current DTC clears when the malfunction is no longer present. |
• | A history DTC clears when the module ignition cycle counter reaches the reset threshold, without a repeat of the malfunction. |
The following can cause the code to set as history:
• | An intermittent problem of the ignition mode switch |
• | The ACC/OFF button of the ignition mode switch was pressed for more than 30 seconds. |
