Pinpoint Routine 

  

NOTE:  If the pinpoint routine requires to connect VMM or DMM, abort the procedure 

(VMM/DMM is not applicable for Mazda dealers).  

• 

This menu offers various tests to isolate the root cause of a fault. A pinpoint routine is 
usually suggested when a functional test in a diagnostic routine failed. In addition most 
DTCs retrieved during Self Test have pinpoint routines associated. 

NOTE:  If a fault was initially detected in a functional test and a pinpoint routine has been 

carried out, this functional test must be repeated to ensure the fault is fixed. If a fault 
was first detected in Self Test and a pinpoint routine has been carried out, then Self 
Test should be carried out once more to ensure the fault is no longer present. 

• 

A pinpoint routine usually consists of the following items:  

– 

Data link monitor  

– 

Digital multimeter  

– 

Pinpoint test

Data Link Monitor 

  

• 

The DLM (Data Link Monitor) is very similar to the Datalogger, i.e. it allows the user to 
monitor the PIDs of a certain system. The main difference is that all the signals are pre-
selected and automatically configured. As a result it is possible to monitor all the 
necessary signals associated with the component or subsystem without making any 
settings. Additional guidance may be available in the form of an information screen that 
is displayed before the DLM starts. 

NOTE:  The DLM is a non-intrusive tool, i.e. the system or component can be monitored 

without disconnecting components or modules. Therefore the DLM is the preferred 
tool for trying to find the root cause of an intermittent fault.
