Component Testing
Note: Depending on the application, the relay coil resistance will be within one of the following ranges.
1. Test for one of the following resistance specifications between terminals 85 and 86 of the KR75 powertrain relay:
* 70-110 ohm
* 200-250 ohm
瀚慖f not within the specified range, replace the KR75 powertrain relay.
2. Test for the infinite resistance between the following terminals of the KR75 powertrain relay:
* 30 and 86
* 30 and 87
* 30 and 85
* 85 and 87
瀚慖f not the specified value, replace the KR75 powertrain relay.
3. Install a 20 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground. Test for
less than 2 ohm between terminals 30 and 87.
瀚慖f greater than the specified range, replace the KR75 powertrain relay.
Repair Instructions

Diagnostic Instructions
* Perform the Diagnostic System Check - Vehicle (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System
Check - Vehicle) prior to using this diagnostic procedure.
* Review Strategy Based Diagnosis (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Strategy Based Diagnosis) for an
overview of the diagnostic approach.
* Diagnostic Procedure Instructions (See: Testing and Inspection/Initial Inspection and Diagnostic Overview/Diagnostic Procedure
Instructions) provides an overview of each of the diagnostic category.
DTC Descriptor
DTC P0700
- Transmission Control Module (TCM) Requested MIL Illumination
Circuit/System Description
The diagnostic trouble code (DTC) indicates that an emission related transmission DTC set in the transmission control module (TCM). The engine
control module (ECM) receives the TCM information over the serial data circuit. The ECM turns ON the malfunction indicator lamp (MIL) when
the TCM sends a message over the serial data circuit requesting MIL illumination. The DTC information for the ECM will only display DTC
P0700, but the Freeze Frame/Failure Records data will display the transmission DTC that set.
Conditions for Running the DTC
* The ignition is ON or the engine is operating.
* DTC P0700 runs continuously.
Conditions for Setting the DTC
The ECM receives a serial data message from the TCM requesting the ECM to turn ON the MIL lamp.
