RA8 — diagnostic time claimed on top of an assembly repair
Quick answer: RA8 is the GCS message code for a standalone 85-41 diagnostic operation claimed on top of a powertrain assembly repair whose flat time already includes access and diagnosis. It is the diagnostic-specific version of an overlap rejection. Drop the separate diagnostic line when the assembly flat already covers that work.
RA8 at a glance
Diagnostic time claimed on top of an assembly repair — Chrysler GCS message code.
| Why it fires | A standalone 85-41 diagnostic line sits beside a powertrain assembly repair whose published flat time already includes access and diagnosis. |
|---|---|
| What it costs | A round trip, and a diagnostic line that was never claimable in that shape to begin with. |
| How it clears | Remove the standalone diagnostic line. Where diagnostic time genuinely exceeds what the flat covers, claim it as actual time against technician punches instead. |
| Where it overlaps LG4 | Same principle, narrower target. LG4 is any two operations sharing access; RA8 is diagnostic time specifically. |
What causes RA8, and what actually clears it
Why the diagnostic line is already paid
A powertrain assembly operation's flat time is built to include getting to the component and establishing what is wrong with it. Adding an 85-41 line next to it asks Chrysler to pay for diagnosis twice. Base-level Chrysler dealers can only claim diagnostic time as total actual time minus the flat-rate repair time, which is the same rule stated arithmetically: overlapping diagnostic time is subtracted, not stacked.
The actual-time math that keeps it clean
Claimable actual-time hours are total punched hours minus any hours already paid flat on the same job. On one repair order, 6.70 punched hours against 0.4 paid flat left 6.3 hours supportable, more than the store had claimed. On another, a technician had billed 2.5 hours of diagnosis, but 6.38 punched hours against 4.5 already claimed flat capped the defensible number at 1.8. On a third, 5.69 punched against 7.2 already flat left nothing at all, and the line correctly came off. Claiming actual time above what the punches support is exactly what an auditor adjusts down later.
The wiring-repair convention
When a technician repairs wiring itself — cut, solder, re-pin — Chrysler's manual puts all the labor for that repair on one wiring operation, claimed as actual time and backed by punches. Diagnosis, the repair, and reassembly all belong on that single line. Scattering the work across separate component operations plus a separate diagnostic line is both wrong against the manual and direct RA8 and LG4 exposure.
An actual-time code needs punches behind it
An operation shaped as an actual-time code is only valid with backing time-punch data. Submitting one with the hours unfilled is a common miss, and it survives manual review easily: the code itself is present and correct, so a reviewer scanning for missing codes sees nothing wrong while the hours quietly read as unsupported.
How to stop RA8 recurring
The checks that keep it off the next claim.
- 01
Before adding an 85-41 line, check whether the repair's flat time already includes diagnosis. On powertrain assembly work it usually does.
- 02
Claim diagnostic time as actual time only when punched hours exceed hours already paid flat on the same job, and only up to that difference.
- 03
Put every hour of a wiring repair on one wiring operation as actual time, backed by punches.
- 04
Confirm any actual-time coded line has its punch-derived hours filled in, not just the code present.
- 05
Never claim a standalone 85-41 alongside an RSU or service bulletin repair.
Frequently Asked Questions
- What does GCS code RA8 mean?
- RA8 is the GCS message code for a standalone 85-41 diagnostic operation claimed on top of a powertrain assembly repair whose flat time already includes access and diagnosis. It is the diagnostic-specific version of an overlap rejection. Drop the separate diagnostic line when the assembly flat already covers that work.
- What is the difference between RA8 and LG4?
- They fail for the same reason at different scopes. LG4 is any two labor operations billing the same access or removal time. RA8 is aimed specifically at diagnostic time claimed on top of an assembly repair that already includes it.
- How much diagnostic time can we actually claim?
- Total punched hours minus any hours already paid flat on the same job. If a technician punched 6.38 hours and 4.5 hours were already claimed flat, the defensible actual-time number is 1.8, regardless of what was originally billed. If the flat time already exceeds the punches, there is nothing left to claim.
- Does Forge check diagnostic lines before submission?
- Yes. Forge reads per-line clocked hours off CDJR repair orders, so a draft that stacks a diagnostic operation on an assembly repair is flagged with RA8 and LG4 named, and an actual-time line missing its punch-derived hours is flagged too. Your administrator sees the reason and decides.

Portals change, and a rule’s behavior can change with them. Treat this as a practitioner’s note, check it against your own claims, and follow your dealer agreement and your manufacturer’s published policy where the two differ.
