Step 5.6: Test the TEC-2401 and associated wiring.
1. Connect the main wire harness P01 connector to the TEC-2401
2. Use a multimeter to measure the resistance between the main wire harness P37 connector, pins A and B
58). The reading should be 148 k to 181 k ohms (148,000 to 181,000).
Pass The resistance reading was good. Go to Step 5.7.
Fail If the resistance reading was not good, go to Step 5.6.1.
Step 5.6.1: Test the TEC-2401 wiring.
1. Disconnect the main wire harness P01 connector from the TEC-2401
2. Check for continuity between the following pairs of locations:
