| FITMENT | Fits applications that specify Mopar 05099007AA/5099007AA (replaced by 68002488AA) and cross-references to Mercedes A1705450305 used on R170 SLK and Chrysler Crossfire platforms; always match to the OE number and verify whether the vehicle uses a standalone cube relay or an integrated RCM/K40 relay module. Chrysler Crossfire (2004-2008): All Mercedes-Benz SLK-Class (R170) (1997-2004): All |
| SYMPTOMS | Common signs of a failing fuel pump/engine management relay include crank/no-start, intermittent stalling, no fuel pump prime at key‑on, and DTCs such as P0230 (Fuel Pump Primary Circuit) or P0627 (Fuel Pump “A” Control Circuit/Open). |
| TROUBLESHOOTING | Before replacement, swap with a like relay (if available) to A/B test; verify battery and ground integrity; check for 12V feed and relay control at the socket; inspect for corrosion/burnt pins. On Crossfire/SLK, also inspect the RCM/K40 module solder joints for cracks if issues persist. |
| INSTALLATION | Disconnect battery; remove the relay from the under‑hood fuse/relay panel or extract the RCM/K40 module if applicable; seat the new relay fully and confirm proper orientation per pin layout. Clear codes and confirm fuel pump prime and start. |
| MAINTENANCE | |
| GENERAL NOTES | Some models (e.g., Mercedes R170 SLK and Chrysler Crossfire) may use an integrated Relay Control Module (RCM/K40, A1705450305) rather than a standalone relay. In those cases, the entire module may be required instead of an individual cube relay; match by OE number prior to purchase. |
