20 Most Recent 1992 Oldsmobile Toronado Questions & Answers

I would check the headlamp door open and close relays first. One or both of them may be bad. It might be a bad headlamp door motor assembly as well. Is there anything blocking the doors from closing all the way? Have you tried closing and opening them manually? You can remove the rubber boot from the door motor knob and turn it by hand.

A 1992 model should be OBDI so - code 17 is a problem with spark control which involves the ignition module, and code 47 is not listed for that model. Code 47 is generally used when there is a problem between the engine computer and the body computer, but a 92 model would not have a body computer.

You don't. You take it to a reputable service garage that does front-end alignments and pay them to do it. There is no way to do it by hand.

I'm not 100% positive about a 1992 Toronado, but on my 1986 Toronado the BCM is behind and to the upper left of the glove box, and the ECM is behind the right side kick panel in front of the door. GM had a habit of moving them around from year to year.

The speedometer is electronic. There is no speedo cable. It could either be the speedometer sensor located in the transmission, or the instrument cluster. Is your speedometer a gauge, or an LED display? The gauge can be replaced, but the entire dash cluster will have to be checked if it is an LED display.

ECM should be behind the passenger's side kick panel, under and to the right of the glovebox. The BCM is behind the glovebox, toward the top and to the left.

car stalls while driving or starts sometimes itr turns over but wont always start

Hi Sammy, it's been awhile since i worked on one of these with a VIC...wished i can remember how to scroll through the prompts. However i did a find a shop manual for your Toronado that you might be interested in...these are getting rare also. I'm sure the info you need will be in it. Here is the link if you care to check it out...I hope this helps.

If both have failed at the same time, it can only be a fuse or failed relay. The motors are probably fused separately from the headlights themselves.

Behind dash near floor on passenger side. Unless you have a very strange vehicle cuz I havent seen them anywhere else.

IP cluster fuse. or relay.

To the left of the panel there is a little button that will move vertically. push that all the way up, just before it clicks (the click will turn all interior lights on). If that doesn't work there is a fuse in the glove compartment. i don't have my manual on me but there is a cluster that has instrument panel lighting on it. it usually says IP cluster or something. or have a mechanic go into service mode. I could tell you how to do that but it's kind of confusing without showing you

Reading & Clearing Codes READING CODES (EXCEPT CADILLAC) Fig. 4: Example of a code 12 displayed on the check engine lamp
Since the inception of electronic engine management systems on General Motors vehicles, there has been a variety of connectors provided to the technician for retrieving Diagnostic Trouble Codes (DTC)s. Additionally, there have been a number of different names given to these connectors over the years; Assembly Line Communication Link (ALCL), Assembly Line Diagnostic Link (ALDL), Data Link Connector (DLC). Actually when the system was initially introduced to the 49 states in 1979, early 1980, there was no connector used at all. On these early vehicles there was a green spade terminal taped to the ECM harness and connected to the diagnostic enable line at the computer. When this terminal was grounded with the key ON, the system would flash any stored diagnostic trouble codes. The introduction of the ALOL was found to be a much more convenient way of retrieving fault codes. This connector was located underneath the instrument panel on most GM vehicles, however on some models it will not be found there. On early Corvettes the ALOL is located underneath the ashtray, it can be found in the glove compartment of some early FWD Oldsmobiles, and between the seats in the Pontiac Fiero. The connector was first introduced as a square connector with four terminals, then progressed to a flat five terminal connector, and finally to what is still used in 1993, a 12 terminal double row connector. To access stored Diagnostic Trouble Codes (DTC) from the square connector, turn the ignition ON and identify the diagnostic enable terminal (usually a white wire with a black tracer) and ground it. The flat five terminal connector is identified from left to right as A, B, C, D, and E. There is a space between terminal D and E which permits a spade to be inserted for the purposes of diagnostics when the ignition key is ON. On this connector terminal D is the diagnostic enable line, and E is a ground. The 12 terminal double row connector has been continually expanded through the years as vehicles acquired more on-board electronic systems such as Anti-lock Brakes. Despite this the terminals used for engine code retrieval have remained the same. The 12 terminal connector is identified from right-to-left on the top row A-F, and on the bottom row from left-to-right, G-L. To access engine codes turn the ignition ON and insert a jumper between terminals A and B. Terminal A is a ground, and terminal B is the diagnostic request line. Stored trouble codes can be read through the flashing of the Check Engine Light or on later vehicles the Service Engine Soon lamp. Trouble codes are identified by the timed flash of the indicator light. When diagnostics are first entered the light will flash once, pause; then two quick flashes. This reads as DTC 12 which indicates that the diagnostic system is working. This code will flash indefinitely if there are no stored trouble codes. If codes are stored in memory, Code 12 will flash three times before the next code appears. Codes are displayed in the next highest numerical sequence. For example, Code 13 would be displayed next if it was stored in memory and would read as follow: flash, pause, flash, flash, flash, long pause, repeat twice. This sequence will continue until all codes have been displayed, and then start all over again with Code 12. CLEARING CODES (EXCEPT CADILLAC) Except Riviera, Toronado and Trofeo: To clear any Diagnostic Trouble Codes (DTC's) from the PCM memory, either to determine if the malfunction will occur again or because repair has been completed, power feed must be disconnected for at least 30 seconds. Depending on how the vehicle is equipped, the system power feed can be disconnected at the positive battery terminal pigtail, the inline fuse holder that originates at the positive connection at the battery, or the ECM/PCM fuse in the fuse block. The negative battery terminal may be disconnected but other on-board memory data such as preset radio tuning will also be lost. To prevent system damage, the ignition switch must be in the OFF position when disconnecting or reconnecting power. When using a Diagnostic Computer such as Tech 1, or equivalent scan tool to read the diagnostic trouble codes, clearing the codes is done in the same manner. On some systems, OTC's may be cleared through the Tech 1, or equivalent scan tool. On Riviera, Toronado and Trofeo, clearing codes is part of the dashboard display menu or diagnostic routine. Because of the amount of electronic equipment on these vehicles, clearing codes by disconnecting the battery is not recommended. Riviera, Toronado and Trofeo (Non-CRT/DID Vehicles) — Using The On-Board Diagnostic Display System: First turn the ignition to theON position. On Riviera depress the OFF and TEMP buttons on the ECCP at the same time and hold until all display segments light. This is known as the Segment Check. On Toronado and Trofeo follow the same procedure, however, depress the OFF and WARMER buttons on the ECOP instead. After diagnostics is entered, any OTC's stored in computer memory will be displayed. Codes may be stored for the PCM, BCM, PC or SIR systems. Following the display of OTC's, the first available system for testing will be displayed. For example, 'EC?' would be displayed on Riviera for EOM testing, while on Toronado and Trofeo the message 'ECM?' will appear. The message is more clear on these vehicles due to increased character space in the IPO display area.

1. Depress the 'FAN UP' button on the ECCP until the message 'DATA EC?' appears on the display for Riviera, or 'ECM DATA?' is displayed on Toronado and Trofeo.
2. Depress the 'FAN DOWN' button on the ECCP until the message 'CLR E CODE' appears on the display for Riviera, or 'ECM CLEAR CODES?' is displayed on Toronado and Trofeo.
3. Depressing the 'FAN UP' button on the ECCP will result in the message 'E CODE CLR' or 'E NOT CLR' on Riviera, 'EOM CODES CLEAR' or 'ECM CODES NOT CLEAR' on Toronado and Trofeo. This message will appear for 3 seconds. After 3 seconds the display will automatically return to the next available test type for the selected system. It is a good idea to either cycle the ignition once or test drive the vehicle to ensure the code(s) do not reset. Toronado and Trofeo (CRT/DID Equipped) — Using The On-Board Diagnostic Display System: First turn the ignition switch to theON position. Depress the 'OFF' hard key and 'WARM' soft key on the CRT/DID at the same time and hold until all display segments light. This is the 'Segment Check.' During diagnostic operation, all information will be displayed on the Driver Information Center (DIC) located in the Instrument Panel Cluster (IPC). Because of the limited space available single letter identifiers are often used for each of the major computer systems. These are: E for ECM, B for 6CM, I for IPC and R for SIR. After diagnostics is entered, any OTC's stored in computer memory will be displayed. Codes may be stored for the PCM, BCM, PC or SIR systems. Following the display of OTC's, the first available system for testing will be displayed. This will be displayed as 'ECM?'.
   
4. Depress the 'YES' soft key until the display reads 'ECM DATA?'.
5. Depress the 'NO' soft key until the display reads 'ECM CLEAR CODES?'.
6. Depressing the 'YES' soft key will result in either the message 'ECM CODES CLEAR' or 'ECM CODES NOT CLEAR' being displayed, indicating whether or not the codes were successfully cleared. This message will appear for 3 seconds. After 3 seconds the display will automatically return to the next available test type for the selected system. It is a good idea to either cycle the ignition once or test drive the vehicle to ensure the code(s) do not reset.

This is a common problem and to correct this problem will require the replacement of the fuel sending unit. The fuel sending unit is inside the fuel tank and has the fuel pump mounted in it. This requires the removal of the gas tank and then the fuel sending unit can be removed from the tank.

REMOVAL AND INSTALLATION Fig. 1: Fuel pump unit

1. Disconnect the negative battery cable.
2. Relieve fuel system pressure.
3. Remove fuel filler cap to release fuel tank vapors. Leave cap off until repairs are completed. Gasoline fuel vapors are extremely flammable. Ensure that fuel is stored in a container that can be properly sealed. Never store fuel in an open container. Store container in a safe place away from heat.
4. Remove fuel tank by performing the following:
   1. Step 1: Drain fuel from the tank into an approved container for storage.
   2. Step 2: Raise and safely support the vehicle.

14. Connect rear stabilizer bar to links. Tighten bolts to 42 ft. lbs. (58 Nm).
15. Lower vehicle.
16. Refill tank and install filler cap.
17. Connect negative battery cable.
18. Start engine and check for leaks.

this is most likely a loss of spark to the plugs, to confirm this u will need to check the system for fault codes stored in the cars engine control module/computer. go to the link for full instructions on doing this test, the fault codes and there descriptions are there as well, the test connector in under the dash in front of the steering wheel

Check from the fuse on the blower unit in the fuse box. If the fan unit is worrking and the ac switch is coming on with display , then it is possible that the solenoid is not triggering from the relay which is in th engine room relay box.
Check this fuse,relay or the AC solenoid.

the thermostat may be stuck open, not allowing the the water in the radiator to warm up, or you may have a bad exchange on the dash that won't allow you to turn it from cold to hot.the resevoir is called an overflow resevoir.when the coolant heats up it expands and flows into there, when it cools back down it uses the coolant from the resevoir.
