Error Code P0826: What It Means & What To Do?

<<See All OBD Codes

The trouble code P0826 can be elucidated as Up and Down Switch Input Circuit. P0826 means there is some fault with a circuit for the up and down switch, which is generally because of a disabled manual shifter. This error code would indicate an issue in the electrical circuit of the upshift/downshift switch to the transmission range correlation circuit. The switch, wiring, connectors, and mode actuator are included in the circuit and it is used in automobiles which have manually shiftable automatic transmissions. The other related codes include P0827 and P0828.

Are you tensed because the P0826 fault code is flashing? We have got everything which you need and at equitable prices. You must visit us and we promise that you will never regret your decision. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model.

What causes this problem with the Up and Down Switch Input Circuit?

• The wiring and connectors might be shorted or disconnected
• Problem of liquids spilled on the upshift/downshift switch

Here are some steps which you should follow in order to diagnose this fault code:

• You should execute a visual inspection of all wiring, connectors, and constituents related with the upshift/downshift switch circuit.
• Now if everything turns out in good condition, then you should attach the scanner to the diagnostic connector and all freeze frame data and stored trouble codes should be downloaded as it would be very helpful further diagnosis.
• The next step is to clear the code and see if it returns upon testing the system.
• If the code returns check the reference voltage and ground signal of the upshift/downshift switch and actuator.
• If either is open, then all the related control modules should be disconnected before the continuity is being tested as well as resistance of all circuits. Disconnect the modules as it would be helpful in preventing the damage from a misplaced investigation when the circuits are being checked.
• The manufacturer's wiring diagram should also be used by a mechanic to test all related circuits using the volt/ohmmeter and then compare their findings to the manufacturer's specifications.
• After that the code should be cleared up and the entire system should be tested once again, by utilizing a scanner to manually activate the upshift switch.
• Now if the code is returning once again, then you should disconnect and test the powertrain control module for the default.
• The mechanic can also inspect the normal/performance switch if the transmission mode selector fails to operate manually.
• Then you should clear the code once more and test the system to see if the trouble code is returning back again or not.

Common Mistakes When Diagnosing The P0826 Code

• A lot of people make a big mistake of attempting to diagnose transmission wiring. Save yourself a big headache and make sure that you are addressing the spilled liquid on the upshift/downshift switch before beginning your diagnosis.
