Conditions for Clearing the MIL/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 control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.
Clear the MIL and the DTC with a scan tool.

DTC P1362

Step	Action	Values	Yes	No
Schematic Reference: Engine Controls Schematics Connector End View Reference: Engine Controls Connector End Views or Powertrain Control Module (PCM) Connector End Views
1	Did you perform the Diagnostic System Check-Engine Controls?	-	Go to Step 2	Go to Diagnostic System Check - Engine Controls
2	Observe the Freeze Frame/Failure Records for this DTC. Turn OFF the ignition for 30 seconds. Start the engine. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure records. Did the DTC fail this ignition?	-	Go to Step 3	Go to Intermittent Conditions
3	Is P1361 also set?	-	Go to Step 6	Go to Step 4
4	Turn OFF the ignition. Disconnect the powertrain control module (PCM). Turn ON the ignition, with the engine OFF. Probe the ignition control (IC) timing signal circuit of the ignition control module (ICM) with a test lamp connected to a good ground. Does the test lamp illuminate?	-	Go to Step 5	Go to Step 11
5	Turn OFF the ignition. Leave the PCM disconnected. Disconnect the ICM connector. Turn ON the ignition, with the engine OFF. Probe the IC timing signal circuit of the ICM with a test lamp connected to a good ground. Does the test lamp illuminate?	-	Go to Step 12	Go to Step 10
6	Turn OFF the ignition. Disconnect the PCM. Disconnect the ICM. Probe the IC timing control circuit of the ICM with a test lamp connected to battery voltage. Does the test lamp illuminate?	-	Go to Step 13	Go to Step 7
7	Leave the ignition OFF. Leave the PCM disconnected. Leave the ICM disconnected. Probe the IC timing signal circuit of the ICM with a test lamp connected to a good ground. Does the test lamp illuminate?	-	Go to Step 14	Go to Step 8
8	Leave the ignition OFF. Leave the PCM disconnected. Leave the ICM disconnected. Test for a short between the IC timing control and IC timing signal circuits. Refer to Wiring Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 17	Go to Step 9
9	Leave the ignition OFF. Reconnect the ICM. Leave the PCM disconnected. Turn ON the ignition, with the engine OFF. Measure the resistance between the IC timing control circuit of the ICM and a good ground. Observe the DMM while probing the IC timing signal circuit of the ICM with a test lamp connected to battery positive voltage. Does the resistance switch between the two indicated ranges?	100-600 ohm to 6,000-10,000 ohm	Go to Step 11	Go to Step 10
10	Test for shorted terminals or for a poor connection at the ICM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the conditions?	-	Go to Step 17	Go to Step 15
11	Test for shorted terminals or for a poor connection at the PCM. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems. Did you find and correct the condition?	-	Go to Step 17	Go to Step 16
12	Repair the short to voltage in the IC timing signal circuit of the ICM. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair?	-	Go to Step 17	-
13	Repair the short to ground in the IC timing control circuit of the ICM. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair?	-	Go to Step 17	-
14	Repair the short to ground in the IC timing signal circuit of the ICM. Refer to Wiring Repairs in Wiring Systems. Did you complete the repair?	-	Go to Step 17	-
15	Replace the ICM. Refer to Ignition Control Module Replacement . Did you complete the replacement?	-	Go to Step 17	-
16	Replace the PCM. Refer to Powertrain Control Module (PCM) Replacement . Did you complete the replacement?	-	Go to Step 17	-
17	Clear the DTCs with a scan tool. Turn OFF the ignition for 30 seconds. Start the engine. Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records. Did the DTC fail this ignition?	-	Go to Step 2	Go to Step 18
18	Observe the Capture Info with a scan tool. Are there any DTCs that have not been diagnosed?	-	Go to Diagnostic Trouble Code (DTC) List	System OK
