Monitor Description |
Description of what the ECM monitors and how it detects malfunctions (monitoring purpose and details). |
Related DTCs |
A group of diagnostic trouble codes that are output by the ECM based on the same malfunction detection logic. |
Typical Enabling Conditions |
Preconditions that allow the ECM to detect malfunctions. With all preconditions satisfied, the ECM stores a DTC when the monitored value(s) exceeds the malfunction threshold(s). |
Sequence of Operation |
Order of monitor priority, applied if multiple sensors and components are involved in a single malfunction detection process. Each sensor and component is monitored in turn and subsequent items are not monitored until the previous detection operation completes. |
Required Sensors/Components |
Sensors and components used by the ECM to detect each malfunction. |
Frequency of Operation |
Number of times the ECM checks for each malfunction during each driving cycle. "Once per driving cycle" means that the ECM only checks for malfunctions once during a single driving cycle. "Continuous" means that the ECM checks for malfunctions whenever enabling conditions are met. |
Duration |
Minimum time for which the ECM must detect continuous deviation in monitored value(s) in order to store a DTC. Timing begins when typical enabling conditions are met. |
Typical Malfunction Thresholds |
Value beyond which the ECM will determine that there is a malfunction and stores a DTC. |
MIL Operation |
Timing of MIL illumination after a malfunction is detected. "Immediate" means that the ECM illuminates the MIL as soon as a malfunction is detected. "2 driving cycles" means that the ECM illuminates the MIL if the same malfunction is detected again during the next driving cycle. |

ON-VEHICLE INSPECTION
PROCEDURE
1. INSPECT ENGINE OIL LEVEL
(a) Warm up the engine, and then stop the engine and wait for 5 minutes.
(b) Check that the engine oil level is between the low level and full level marks
on the dipstick.
If low, check for leakage and add en ...
Pressure Control Solenoid "C" Performance (Shift Solenoid Valve SL3) (P0796)
SYSTEM DESCRIPTION
The ECM uses the vehicle speed signal and signals from the transmission revolution
sensors (NT, SP2) to detect the actual gear (1st, 2nd, 3rd, 4th, 5th or 6th gear).
The ECM compares the actual gear with the shift schedule in the ECM memory to
detect mechanical problems of t ...
Dtc Check / Clear
DTC CHECK / CLEAR
1. DTC CHECK
HINT:
When DTC B1650/23 is detected as a result of troubleshooting for the
airbag system, troubleshoot the occupant classification system.
Use the Techstream to read and clear DTCs, otherwise the DTCs cannot
be read and cleared.
(a) Check ...
