help fix code p1605
Where to start i hope its only the bad battery. |
Which is it...P1606 or P1605?
|
It must be P1605 - there is no P1606.
P1605 is "Signal from TCM (Transmission Control Module) is not received by ECM". Possible causes are: * Harness or connectors (The communication line circuit between ECM and TCM is open or shorted.) * TCM (Transmission Control Module) * Dead (Weak) battery Check the wire continuity between TCM pin 45 and ECU pin 6. This is a red wire. |

I have already put it another TCM (re-conditioned part) but the check engine light still appears. Does anyone know what I can do or did you solve your own problem. could someone reply. thx. |
