2005 cts won't sift out of park, press the brake pedal and start the car, just won't shift out of park


You probably have a problem with

Automatic Transmission Shift Lock Control System
The automatic transmission shift lock control system is a safety device that prevents an inadvertent shift out of PARK when the engine is running. The driver must press the brake pedal before moving the shift lever out of the PARK position. The system consists of the following components.
• The automatic transmission shift lock control solenoid
• The brake switch
• The rear integration module (RIM)
• The transmission control module (TCM) or powertrain control module (PCM)
With the ignition ON, battery positive voltage is supplied to the automatic transmission shift lock control solenoid from the ignition 3 relay. The automatic transmission shift lock control solenoid is controlled by the rear integration module. When the rear integration module (RIM) receives a class 2 serial data message from the transmission control module (TCM) or powertrain control module (PCM) indicating that the shift lever is in the PARK position the rear integration module (RIM) grounds the automatic transmission shift lock control solenoid control circuit. This causes the solenoid to energize mechanically locking the shift lever in the PARK position. When the driver presses the brake pedal the rear integration module receives the brake applied signal and turns off the ground to the automatic transmission shift lock control solenoid control circuit. This allows the shift lever to be moved out of the PARK position.

2004 Deville: I am getting code B 1390 - Device Voltage Reference Input Circuit Malfunction - what do I do?


DTC B1390 -The DIM has an internal battery voltage sensor and a reference voltage. The DIM compares these two voltages via the two battery positive voltage circuits every 300 milliseconds. Do you know what the DIM is ?

Conditions for Setting the DTC
This code shall be set after 10 consecutive readings that the two battery positive voltages differ by 1 volt or greater.


Turn OFF the ignition.
Disconnect the dash integration module (DIM).
Turn ON the ignition, with the engine OFF.
Measure and record the voltage from both battery positive voltage circuits of the DIM to both ground circuits of the DIM.
Compare the two recorded DIM battery positive voltage circuit voltages.
Is the voltage difference less than the specified value?
1 V
YES - Go to Step 5
NO - Go to Step 3

Test both DIM battery positive voltage circuits for a high resistance or an open. Refer to Circuit Testing and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?

Dash Integration Module (DIM)
The various DIM input and output circuits are described in the corresponding functional areas as indicated on the DIM electrical schematics.
The DIM functions include the following:
• Class 2 communication requiring DIM interaction.
• Control of exterior lamps.
• Control of front fog lights.
• Control of the headlights.
• Headlamps on with wiper input.
• Hood ajar switch input w/export.
• Horn relay control.

How do I repair the four wheel drive on a 1999 Ford Ranger XLT?


It depends on what is wrong , is the 4x4 light flashing ? Are you aware of the complexity of the 4x4 system ? Has a electronic control module , has the ability to set an store DTC'S - diagnostic trouble codes !
Transfer Case The four wheel drive system is an electronic shift 4X4 system that allows the operator to choose between three different modes. The operator can switch 4X4 HIGH modes at any speed. To engage or disengage 4X4 LOW the vehicle speed must be less than 5 kph (3 mph), the brake depressed, and the transmission must be in NEUTRAL.
The shift motor sense plate, an integral part of the electronic shift motor, informs the generic electronic module (GEM) of the transfer case shift motor and contact plates A, B, C and D position.
The digital transmission range (TR) sensor is located on the LH side of the transmission, and informs the GEM when the transmission is in the NEUTRAL position.
The electronic shift motor is mounted externally at the rear of the transfer case. It drives a rotary cam which moves the mode fork and range fork within the transfer case between the 4X4 HIGH, 4X4 LOW and 2WD range positions.
When the GEM verifies the completion of the transfer case shift from 2WD to 4X4 HIGH (reading the contact plate positions), the GEM will then energize both pulse vacuum hublock (PVH) solenoids (supplying ground for 45 seconds). The PVH solenoid will allow a HIGH flow of intake manifold vacuum to the "wheel end hublocks", engaging the wheel end hubs to the front differential and transfer case to achieve four wheel drive.
Here are just a few DTC'S the system can set an store in the module !
P1804 4WD High Indicator Circuit Failure GEM GO to Pinpoint Test C . P1806 4WD High Indicator Short to Battery GEM GO to Pinpoint Test C . P1808 4WD Low Indicator Circuit Failure GEM GO to Pinpoint Test C . P1810 4WD Low Indicator Short to Power GEM GO to Pinpoint Test C . P1812 4WD Mode Select Switch Circuit Failure GEM GO to Pinpoint Test A . P1815 4WD Mode Select Switch Circuit Short to Ground GEM GO to Pinpoint Test A . P1820 Transfer Case CW Shift Relay Circuit - Failure GEM GO to Pinpoint Test A . P1822 Transfer Case CW Shift Relay Coil Short to Power GEM GO to Pinpoint Test A . P1824 4WD Electric Clutch Relay Circuit Failure GEM GO to Pinpoint Test A . P1826 4WD Low Clutch Relay Short to Power GEM GO to Pinpoint Test A . P1828 Transfer Case CCW Shift Relay Coil Circuit Failure GEM GO to Pinpoint Test A . P1830 Transfer Case CCW Shift Relay Coil Short to Battery GEM GO to Pinpoint Test A . P1838 Transfer Case Shift Motor Circuit Failure GEM GO to Pinpoint Test A . P1846 Transfer Case CONTACT PLATE "A" Circuit Failure GEM GO to Pinpoint Test A . Now are you sure you really want to mess with this ? You would need a factory diagnostic scan tool to check this out before you start replacing parts !

Without a Sams Photofact or a service manual I would go directly to the Power IC which is the largest Integrated Circuit mounted to a large heat sink. If you see any fuses they are probably for the power supply since any fused circuit on the speaker output would be ineffective because the IC would be damaged before the fuse would blow, but you need to check them anyway. Since the short was at the speaker output your problem should be at the final stage of amplification, which is the Power Amp IC. Prior to the early 70's you would have transistors mounted to a heat sink which could be individually checked and replaced. Then manufactures started to use the Power Amp IC which are more costly but eliminate having to find matched pair transistors. All you can check on the Power Amp IC is if you have an input using an oscilloscope or signal tracer and the power to the IC. If you have an input signal and power to the device with no output, I would replace the IC. Unless you have a test circuit for the IC you cannot test it completely unless you have a device like a Huntron Tracker or build a test circuit using a signal generator and a power supply to measure the gain of the IC with an oscilloscope. Short of ordering a service manual this is a good place to start.

hi,
If possible check the crossover circuit board. There will be two or more ICs ( integrated circuits). fast of all just replace all the ics in that board. That ics will be very cheep in price. after replacing those ics make a test. if then also the cracking sound hears then you have to check the components amplifier board.
