Other Monitor
NOTE:
The Other Monitor passively monitors for opens, shorts, grounds and out of range sensor parameters. It runs continuously.
This monitor applies to DTCs not covered by the rest of the monitors. Following conditions must be met during the test:
- Engine coolant temperature must be 176°F (80°C) or more.
- Atmospheric temperature is 41°F (5°C) or more.
- Selector lever is in "D" range.
Monitor takes about 10 minutes to complete. To run monitor, use illustration. See Fig 1. Perform steps as follows:
- Remove all test equipment from vehicle and install all components and connectors that were removed or disconnected during testing.
- After engine is completely warmed up, turn ignition off.
- Start engine and quickly accelerate to 35-40 MPH.
- Drive for 5 minutes or more at 35-40 MPH.
- Return vehicle to shop and let idle. While engine is idling, A/C switch must be in OFF position, lights and accessories must be off, steering wheel must be straight ahead, and automatic transmission must be in "P" range. After idling for 5 minutes, turn ignition off. Confirm that DTCs are not set. If DTCs are set, refer to specific DTC and troubleshoot problem in DIAGNOSTIC TESTS. See DIAGNOSTIC TROUBLE CODE DEFINITIONS for directions.
