DESCRIPTION The power
steering ECU (rack and pinion power steering gear assembly) determines
whether an incompatible hybrid vehicle control ECU, main body ECU
(multiplex network body ECU) or skid control ECU (brake booster with
master cylinder assembly) is installed based on the identification
information. |
DTC No. | Detection Item |
DTC Detection Condition | Trouble Area |
Warning Indicate | Return-to-normal Condition |
Note | | C1567 |
Error in Matching of ECUs |
- An incompatible hybrid vehicle control ECU is detected
- An incompatible main body ECU (multiplex network body ECU) is detected
- An incompatible skid control ECU (brake booster with master cylinder assembly) is detected
|
- Incorrect hybrid vehicle control ECU
- Incorrect main body ECU (multiplex network body ECU)
- Incorrect skid control ECU (brake booster with master cylinder assembly)
- Rack and pinion power steering gear assembly
| EPS warning light: Comes on |
