This question is mostly for other techs out there who are flat rate and have (or have had) access to at least two sources.
Our dealership used to go off of warranty time and mark c-pay work up a certain percentage...We also used to add .5 to 1.0 for diag if needed...Effective TODAY we have new policies.
After lenghty discussions (arguments) with our new owners and our service advisors it has been decided FOR us that we are no longer to use the warranty time + mark up...We can ONLY use the big companies...Chiltons, Motor, alldata, etc..........This is what independent shops use, so I guess it is fair.
IN ADDITION, and the BIG kicker is this....Unless it says to add for diag, we do not get paid for diag....They "assume" motor, chiltons, Mitchell and alldata R&R time has "diag" built in.....
We used to get overlapping time for diag and the repair, which has been taken away..I understand that...What gets me is their taking away our diag for items that are not overlapping...
Example is a ect sensor on a high idle/rich running engine...To diag a bad ect you put a thermometer in the coolant reservoir and compare the true temp readings to the readings on the scan tool..This step is obviously after checking fuel trims, fuel pressure, etc....This is diag that isn't included in the labor time and we should be paid for it..
We have access to alldata and that's it....I don't see any diag time in alldata, NONE. I also don't see any disclaimers saying that it is not built in.... If I look up ect replacement I get R&R time and that's it....no diag time..and the time says for "parts and labor" it doesn't say includes diag....They tell me that the big three say to add so many tenths for diag of a certain component, but I don't see it....I got on mitchells website and according to them they say that diag time is "not included" in their R&R time....see the link.

Do the book companies ... Chiltons, Motor, Mitchell...Have diag time in their book for all items...For example a thermostat or ect sensor?? What about diag time for a window regulator or pressure testing a cooling system?? What about diagnosing a check engine light for a evap code...Do they add diag time for test drives or pinpointing chassis noises?? What about confirming power to a inop blower motor??
So I ask the other techs out there.. How do you charge for diag?? Also which of these books have the most inflated labor times...Obviously I'm going to bid the job out with the book that charges the most time... SO which book inflates their times the most and which one (if any) has more add lines for diag??
