Transmission Control Module (TCM)
TCM
| DTCs | P0604 - RAM fault present P0605 - ROM fault present P0607 - CPU reset fault P06B8 - NVRAM error |
| Monitor Execution | Once per driving cycle at start-up except reset monitoring which is continuous |
| Monitor Sequence | None |
ADLER (CHIP THAT CONTROLS THE TRANSMISSION SOLENOIDS)
| DTCs | P1636 - lost communication (over internal SPI network) with ADLER chip |
| Monitor Execution | Electrical - Continuous |
| Monitor Sequence | Transmission enters mechanical limp home (get P, R, N and 5M with open TCC and max line) if the main micro cannot communicate with the ADLER chip |
TRANSMISSION ID (TRID) BLOCK (CONTAINS SOLENOID CHARACTERIZATION DATA
| DTCs | P163E - Programming error (checksum fault) P163F - TRID data not programmed |
| Monitoring Execution | Start-up - TRID is a portion of flash memory, either it is present at start-up or not |
| Monitor Sequence | Transmission solenoid data missing, enters limited operating mode (P, R, N and 3rd gear with open TCC). |
