Start relay is installed in FAM. TCM output 12V signal only "P, N" range, this signal grounded to FAM internal circuit through coil of start relay2. start signal of ignition s/w inputted, internal s/w closed that of starter relay 2 and that signal grounded to vehicle body through coil of starter relay1 that is located in Engine room junction box. Then KEY SW2 signal supplied to start motor through starter relay1 s/w and drives start motor.
TCM set this code If impossible starting in "P,N" range condition orimpossible starting in "P,N" range condition.(MIL OFF)
Item | Detecting Condition | Possible Cause |
DTC Strategy |
•
Check the P/N range signal. |
•
Faulty in starter relay2(inside FAM)
•
Mechatronics (Valve-body + TCM) |
Enable Conditions |
•
"IG KEY" ON
•
Power supply to sensor is normal
•
No error in inhibitor s/w | |
Threshold Value |
•
Impossible starting in "P,N" range condition > 800mS (Faulty in starter relay)
•
Impossible starting in "P,N" range condition > 800mS (Faulty in P/N s/w) | |
Diagnostic Time |
•
0.45second | |
Fail Safe |

- (priority : 1) |
The function with the higher priority will aiways take precedence. However, a low-priority is not overruled by a higher priority function.
Functions from different priority categories can also run in parallel. It is important to note which function will take precedence in this case.
In such an event it is possible for a substitute function with low priority not be carried out if a second, higher-priority function is present. This has been taken into account when compiling the priority list and is international.
The mechanical emergency run function must always have the highest priority, since from the electrical standpoint it is the only safe condition.
