代码，是P0710和P1637。车店说有一个负责换档信号的部件（ESM，electric shift
module，又叫做Shifter bezel）坏了，需要更换。部件本身800元，工钱200元。
对这个部件俺是一窍不通，在网上搜索了一下，看到的都列在下面了。
俺想请教的是，换这个东西工钱200元是不是太贵？部件价格俺还没有查到，实在是太
笨了。
大切诺基是2005年的（二手），里程54k。网上老美说ESM这个情况很多，有人说非换不
可也有人说reset一下就能好，莫衷一是。
多谢！
P0710-TRANSMISSION TEMPERATURE SENSOR CIRCUIT
Theory of Operation
The Electrohydraulic Control Unit Assembly of the NAG1 transmission contains
a temperature sensor to monitor the transmission oil temperature. This
sensor is wired in series with the transmission Park/Neutral switch. The
Transmission Control Module (TCM) expects to see a valid voltage level from
the sensor when the shifter is in Reverse or any forward Drive position. The
TCM also expects to see an open circuit condition when the shifter is in
the Park or Neutral position. When the controller detects an open circuit
when in Reverse or any forward drive position the DTC will set. Note: Due to
a open circuit condition in Park or Neutral, the TCM substitutes the
Transmission Temperature reading with Engine Temperature when in Park or
Neutral
When Monitored:
Continuously with the ignition on.
Set Condition:
When the TCM detects an open circuit when in Reverse or any forward drive
position the DTC will set.
Possible Causes
P1637 TCM INTERNAL-EEPROM PERFORMANCE
Theory of Operation
The Transmission Control Module (TCM) performs various internal tests to
verify proper controller operation. This DTC indicates that there is an
internal error with the controllers Random Access Memory. If detected, the
controller will enter Limp-in mode and illuminate the MIL.
When Monitored:
Continuously with the ignition on.
Set Condition:
If the TCM indicates that there is an internal error with the controllers
Random Access Memory.
Possible Causes
TRANSMISSION CONTROL MODULE
Repair
Using the schematics as a guide, check the Transmission Control Module (TCM)
terminals for corrosion, damage, or terminal push out. Pay particular
attention to all power and ground circuits. If no problems are found,
replace the TCM per the Service Information. |

很有可能还没过保
“You gotta bring it into the dealership so the ESM can get reflashed. As
long as the check engine light is on and the car isnt working right. The
dealership has the only tool to fix it or replace it, You should be covered
under the powertrain warranty since your under 70k miles.

读CODE说要换ESM
直接去店里换了新电池 15分钟
灯灭 后来再没亮 |
