Drive Mode Preparation
|
1
|
• Connect the M-MDS to the DLC‐2.
• Turn the ignition switch to the ON position (Engine off).
• Turn the ignition switch off then to the ON position (Engine off).
• Select the appropriate vehicle and engine qualifier.
• Clear the continuous DTCs and reset the emission monitors information in the PCM.
|
Bypasses the engine soak timer. Resets the OBD monitor status.
|
2
|
• Start the engine without turning the ignition switch off.
|
||
3
|
• Idle the engine for 15 s.
• Drive at 64 km/h {40 mph} until the ECT is 76.7 °C {170 °F} or more.

Prep for Monitor Entry
|
4
|
• Is the IAT within 4.4—37.8 °C {40—100 °F}?
|
Engine warm-up and provides IAT input to the PCM.
|
HO2S
|
5
|
• Cruise at 64 km/h {40 mph} for up to 5 min.
|
Executes the HO2S monitor.
|
EVAP
|
6
|
• Cruise at 64—89km/h {40—55 mpr} for 10 min.
|
Executes the EVAP emission monitor.
|
Catalyst
|
7
|
• Stop the vehicle and go to traffic conditions.
• Include five different constant cruise speeds, ranging from 32—89 km/h {20—55 mph} over a 10 min period.
|
Executes the catalyst efficiency monitor.
|
CCM (Engine)
|
8
|
• Stop the vehicle.
• Idle the engine for 2 min with the selector lever in the D range.
|
Executes the idle air control portion of the CCM.
|
CCM (Transaxle)
|
9
|
• Stop the vehicle.
• In overdrive, moderately accelerate to 81 km/h {50 mph} and cruise for 15 s or more.
• Stop the vehicle and repeat without overdrive to 64 km/h {40 mph} cruising for 30 s or more.
• While at 64 km/h {40 mph}, activate overdrive and accelerate to 81 km/h {50 mph} and cruise for 15 s or more.
• Stop the vehicle for 20 s or more.
• Repeat Step 9 five times.
|
Executes the transaxle portion of the CCM.
|
Misfire and Fuel
|
10
|
• Stop the vehicle.
• Accelerate to 97 km/h {60 mph}.
• Decelerate at closed throttle until reaching 64 km/h {40 mph}(no brakes).
• Repeat 3 times.
|
Allows learning for the misfire monitor.
|
Readiness Check
|
11
|
• Access the ON BOARD SYSTEM READINESS to verify the OBD monitoring status.
|
Determines if any monitor has not been completed.
|
Pending Code Check and EVAP Monitor Bypass Check
|
12
|
• Verify that no pending code has been stored. If any pending code has been stored, perform the appropriate DTC inspection.
(See DTC TABLE [MZI-3.7].)
• Otherwise, return any incomplete monitor.
• Perform the “EVAP Monitor Bypass“ procedure.
|
Determines if a pending code is preventing the clearing of the DTC P1000.
|
EVAP Monitor Bypass
|
13
|
• Leave the vehicle for 8 h.
• Go to Step 2 then perform from Step 2 to 11.
|
Allows the “bypass“ counter to increment to two.
