SOURCE: Toyota harrier 98 model (OD off )check light

There should be a small pushbutton switch on your shifter, either on the center of the knob if it has the shifter on the steering wheel or if its on the center console, it should be to the side of the release button that you press when switching from park to drive. It means Over Drive is off and that will not allow to engage the last gear when driving. This is useful when hauling a heavy trailer but not good when driving normally cause it may cost you more fuel economy

Backup Lamps
The R-BEC 1 fuse in the underhood fuse block supplies battery positive voltage to the BACKUP LAMP relay through the BACKUP LAMP fuse. When the gear selector is placed in reverse, the body control module (BCM) supplies ground to the BACKUP LAMP relay. This energizes the BACKUP LAMP relay and current flows from the BACKUP LAMP relay to the backup lamps and then to ground. The backup lamps are grounded at G401 and G403.

The transmission range (TR) switch is part of the park/neutral position (PNP) and back-up lamp switch assembly (1), which is externally mounted on the transmission manual shaft. The TR switch contains four internal switches that indicate the transmission gear range selector lever position. The PCM supplies ignition voltage to each switch circuit. By grounding one or more of the switch circuits, the PCM detects the selected gear range by the state change of the switch input. Refer to Transmission Range Switch Logic . Switch input to the PCM is represented on the scan tool as HI and LOW. HI indicates an ignition voltage signal. LOW indicates a zero voltage signal. The four parameters represent transmission range switch signal A,B,C and Parity.

When the transmission is placed into reverse a input to the engine computer is received . The PCM - engine computer sends a massage on the C.A.N serial data network to the BCM - body control module . Which then energizes the back up lamps relay .

Same with the Door locks , controlled by the BCM .

Door Lock System Components
The Power Door Lock System consists of the following components:
• Body control module (BCM)
• Driver door lock switch
• Front passenger door lock switch
• Door lock actuators in each of the doors
• IBCM (PWR) 15-amp fuse
Door Lock System Controls
The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:
• A door lock switch Lock or Unlock actuation
• A keyless entry transmitter actuation
• An automatic door lock actuation
• An automatic door unlock actuation
• A last door closed locking (LDCL) actuation

A/C only works on 3,4 . we assume you mean the blower motor only works on med speed an high speed . This would be for the heat as well . Manual or automatic cilmate control ? The blower motor control module is probably at fault !

What do I replace if my Auto door locks won't work


First off testing would need to be done to determen what the cause is . The door locks on your vehicle are controlled by a computer ,BCM - body control module . The first test would be to check for DTC'S diagnostic trouble codes in the BCM . An to do this you would need a factory scan tool , not a OBD2 code reader . Door Lock System Components
The Power Door Lock System consists of the following components:
• Body control module (BCM)
• Driver door lock switch
• Front passenger door lock switch
• Reversible door lock actuator in each of the doors
• IBCM (PWR) 15-amp fuse
• Driver door cylinder switch, if equipped
Door Lock System Controls
The Power Door Lock System is controlled by the body control module (BCM) and can be activated by any one of the following:
• A door lock switch lock or unlock actuation
• A keyless entry transmitter actuation
• An automatic door lock or unlock actuation
• A last door closed locking (LDCL) actuation
If the driver door cylinder switch feature of the vehicle is functional, the locks may also be operated by a driver door cylinder switch lock or unlock activation.
Your best bet would be to take to a ASE certified repair shop or the dealer.Because if the BCM were the problem an had to be replaced , it would need programming .
Each door lock switch is wired to the body control module (BCM) through a separate door lock/unlock signal circuit. While these circuits are separated between the BCM and respective door lock switch, they are connected into a single circuit within the BCM. The BCM supplies voltage through the door lock/unlock signal circuits to each door lock switch. When either door lock switch is operated, this supply voltage is pulled to ground, providing the BCM with the required lock or unlock signal. In order for the BCM to distinguish between a lock and unlock signal, the lock switch contains two separate paths for this voltage to flow to the same body ground. When the switch is operated to the unlock position, the supply voltage flows to ground through a 1.5K ohm resistor. When the switch is operated to the lock position, the supply voltage flows to ground through a different part of the switch circuit, which has no resistor. The BCM then interprets the flow of voltage as a lock or unlock request and powers the door lock actuators to the appropriate lock or unlock position.

Does anyone know how to rewire a 98 Toyota Avalon cause no one wants to help me bypass the security and I been without a vehicle going on a month


Probably because no one thinks it can be done. I don't think it can be done. You have to convince the engine computer it is getting the right signal from the anti-theft module before it will allow the car to start. The GM system runs off resistor chips in the key. You can "trick" the system to recognize any key if you wire in a "resistor pack" with the correct sized resistance matching the old correct key's resistance reading. See, you just wire in between the key lock cylinder, will be a wire going to the anti theft module (which then signals the computer all is okay to start the engine) -on a GM vehicle you wire in a resistor pack in the wire to the antitheft module. There are approximately 15-20 different resistance readings in those key chips. Maybe Toyota uses a similar- google it!

What causes a malfunction in power locks?


The power door locks are controlled by the BCM -body control module ! The door lock switch is an input to the BCM .
The BCM, upon receipt of a door lock switch lock or unlock signal, will switch the appropriate door lock actuator control circuits to battery positive voltage. The opposing side of the door lock actuators are connected to ground internally within the BCM through the other door lock actuator control circuit and the doors will lock or unlock appropriately.
First thing to do would be check power an ground circuits at the BCM ! Do you have any other systems not working -power windows etc...
The DR/LCK fuse supplies battery positive voltage to the I/P fuse block for the door lock system. The body control module (BCM) supplies and monitors a reference voltage to the door lock switch through the door lock switch lock/unlock signal circuit. The door lock switch also receives a constant ground source. If a door lock switch is placed in the lock position or unlock position, the reference voltage is taken directly to ground and the BCM detects the voltage drop on the signal circuit.
Should have BCM checked for stored DTC'S - diagnostic trouble codes !
Ignition ON, observe the scan tool Driver Door Lock Sw, Psgr Door Lock Sw, Driver Door Unlock Sw and Psgr Door Unlock Sw parameters while using the driver and passenger door lock switches. The parameters should change between Active and Inactive.
?‡'
If the values does not change between the commanded states, refer to Door Lock Switch Malfunction.

Command the driver door and passenger door lock actuators to LOCK and UNLOCK with the scan tool, the doors should LOCK and UNLOCK when changing between commanded states.
?‡'
If a door lock actuator does not perform the LOCK and UNLOCK functions, refer to Door Lock Malfunction

No electric power to left door Fuse and relay are good


Check the wire lume that runs from the body to the door inside a rubber bellow. the wires can break from constant moving and I'm not sure what vehicle you have, but this is a defect for a few vehicles out there the wire can be to short in some cases from cost saving manufacturing. It may be necessary to remove the door panel and remove the harness through the wire opening to be able to move the boot far enough to access the broken wire or even just to check it in some cases.
How I like to repair it, is to put a new wire through the entire pivot point and join it inside the door and body where the wire does not move constantly.

Hope this helps

What can cause doors lock to unlock and then lock again while driving


The indicator for park/neutral is changing on the dash without you moving the shifter?
If so...the park/neutral switch on the transmission...(or could be on shifter housing) is informing the lock control module/body module... that the vehicle has been put in park...thus the door unlock actuation...then..apparently the switch is erroneously informing the lock module that it is in neutral...drive...thus locking the doors....could also be a fault in the general body module...which ..most likely...controls most of the body systems via CAN BUS....Controller Area Network system....
Odd that no codes are in the body/lock module....make sure your scan tool is indeed able to access the body control systems...if not...you need to find a location that will provide that service.

1997 plymouth voyageur locks lock and unlock and interior lights flicker on and off while driving


The "BCM" module on your van has become unreliable.
The BCM is the "Body Control Module" that all these systems go through. The issue is that these are cold soldered and after a time the solder joints break on the computer connection. It is located behind the fusebox underneath the steering wheel.
If you know someone who can solder. You can use an 8mm and a 10mm socket to remove the BCM. Open it up and resolder the joints with a soldering iron. After that everything should be fine.
It is easier than it sounds.

BODY CONTROL MODULE
REMOVAL
Disconnect battery negative cable.
Remove lower steering column cover and knee blocker reinforcement.
Disconnect two wire connectors from bottom of Body Control Module (BCM) Body Control Module .
Remove bolts holding junction block (fuse Panel) to dash panel mounting bracket.
Remove junction block from mounting bracket.
Remove screws holding BCM to junction block.
Slide BCM downward to disengage guide studs on junction block from channels on BCM mounting bracket.
Remove BCM from junction block.
Re-solder Main connection points
INSTALLATION
Reverse the preceding operation.

it is 2004 but use the wiring diagrams to test the wires
(most likely to fail where they flex)
because it is using logic gates disconnect the plug at each end of the wire you are testing or the damn thing will find a few diffrent ways to trick you.
