Diagnostic Trouble Code (DTC) Information

NOTE: HHT malfunction memory readout may display numbers higher then shown in the following chart:

1. DTC's between 2 and 65 = actual error at time of readout
2. DTC's higher then 96 = that previously occurs, ie: DTC code + 96
Example: DTC 18 that occurred previously would become 18 + 96 and be display as DTC 114

Limp Home Mode (X) = Transmission dose not shift, transmission remain in same gear error occurred. After moving shift selector lever to park, cycle ignition key Off, wait 10 seconds, restart engine, engaged gear can be 2nd gear or Reverse only To restore transmission function (if error is nonexistent): clear malfunction memory , cycle ignition key Off, restart engine.

Auto Reset (X) - Error reaction eliminated after error condition ends
Key Reset (X) - E7iqcbon eliminated by cycling ignition key Off/On

A - Limp Home Mode only when malfunctions 22 and 23 occur simultaneously. With implausible signal input, control module defaults to preprogrammed fixed substitution value (L/RR, R/RR = 2500 rpm).
B - With implausible signal input, control module defaults to preprogrammed fixed substitution value
C - With implausible signal input, control module defaults to variable substitution value (with loss of one rear speed sensor input)
D - With implausible signal input, control module defaults to variable substitution value from other half of original of engine control (M120 only)
F - Error induces control module to reinitialize from beginning (reset)
