Timing Check

Print

  1. Before servicing the vehicle, refer to the Precautions section.
  2.  

Before attempting to adjust the ignition timing, be sure of the following:



The engine should be at normal operating temperature.
 
The lights and all accessories should be OFF.
 
The transmission should be inPN
 

  1. Connect scan tool MB991958 to the data link connector
  2.  
  3. Set up the timing light.
  4.  
  5. Start the engine and run at idle.
  6.  
  7. Verify that the idle speed is about 680 rpm.
  8.  
  9. Select scan tool MB991958 actuator test -item number 17-.
  10.  
  11. Check that basic timing is with in standard, it should be 2-8° BTDC.
  12.  
  13. If the base timing is out of specification:
    1. Check to see if the distributor is aligned properly
    2.  
    3. Check to see if the timing belt cover and Crankshaft Position (CKP) sensor installation is conditions.
    4.  
    5. Crankshaft sensing blade conditions.
    6.  

  14.  
  15. Press the clear key on the scan tool, select forced drive stop mode and cancel the actuator test.
  16.  


CAUTION
If the actuator test is not canceled, the forced drive will continue for 27 minutes. Driving in this state could lead to engine failure.

  1. Check that the actual ignition timing is approximately 10° BTDC.
  2.  


NOTE
Keep in mind that the ignition timing may fluctuate by as much as +/-7° BTDC even under normal operation conditions. It is also further advanced by 5-10° BTDC at higher altitudes.

  1. Before servicing the vehicle, refer to the Precautions Section.
  2.  

Before attempting to adjust the ignition timing, be sure of the following:



The engine should be at normal operating temperature.
 
The lights and all accessories should be OFF.
 
The transaxle should be in P or N .
 

  1. Connect scan tool MB991958 to the data link connector
