K_LAM_DIAG_REG_T | | Terminal condition: Engine running | | Voltage condition: none | Condition for fault memory entry | Controller limit for K_LAM_DIAG_REG_T (60s) | Action in service | 1. Check fuel system for leaks, initiate test routine as indicated | | 2. Check exhaust system for leaks | | 3. Check HFM for leaks and correct operation | | 4. Read out oxygen sensor diagnostic data, perform both oxygen sensor test routines as indicated | Fault effect and breakdown warning | Engine runs erratically | | Potential collateral error: Miss errors and lamda error MIL after engine runs 2x | Driver information | Warning light: MIL | Service instruction | None |
