Conditions for Clearing the DTC

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

The DTC will be current for as long as the fault is present.
When the fault is no longer present the DTC will be a history status code.
The history DTC will be cleared after 100 error free ignition cycles, or by using the scan tool clearing DTCs feature.

DTC B1825, B1850, B2355, B2365, or B2375

1	Did you perform the Power Seat Systems Diagnostic System Check?	-	Go to Step 2	Go to Diagnostic System Check - Power Seat Systems
2	Install a scan tool. With the scan tool, observe the Position Sensor parameter in the memory seat module data list. Does the scan tool indicate that the Position Sensor parameter is within the specified range?	0.2-4.7 V	Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems	Go to Step 3
3	Disconnect the position sensor connector. Measure the voltage between the 5-volt reference circuit of the position sensor and a good ground. Does the voltage measure within the specified range?	4.7-5 V	Go to Step 5	Go to Step 4
4	Test the 5-volt reference circuit of the position sensor for the following conditions: Open or high resistance Short to ground Short to voltage Refer to Circuit Testing and to Wiring Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 12	Go to Step 9
5	Connect a 3-amp fused jumper wire between the 5-volt reference circuit of the position sensor and the signal circuit of the position sensor. With a scan tool, observe the Position Sensor parameter. Does the scan tool indicate that the Position Sensor parameter is within the specified range?	4.7-5 V	Go to Step 7	Go to Step 6
6	Test the signal circuit of the position sensor for the following conditions: Open or high resistance Short to ground Short to voltage Refer to Circuit Testing and to Wiring Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 12	Go to Step 9
7	Test the low reference circuit of the position sensor for an open or high resistance. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 12	Go to Step 8
8	Inspect for poor connections at the harness connector of the position sensor. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 12	Go to Step 10
9	Inspect for poor connections at the harness connector of the memory seat module. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 12	Go to Step 11
10	Replace the seat position sensor. Refer to Seat Adjuster Replacement - Front . Did you complete the replacement?	-	Go to Step 12	-
11	Replace the memory seat module. Refer to Memory Seat Control Module Replacement . Did you complete the replacement?	-	Go to Step 12	-
12	Use the scan tool in order to clear the DTCs. Operate the system within the Conditions for Running the DTC as specified in the supporting text. Does the DTC reset?	-	Go to Step 2	System OK
