R **ON A/C 001-049, 051-099, 101-105, 151-158, 201-209,
 A. If the test gives the maintenance message:
 - NO DMC 1 DATA, or

 - NO DMC 2 DATA

 (1) Do the operational test of the Electronic Instrument System (Ref. AMM TASK 31-60-00-710-001).

 (a) If the test gives a different maintenance message, you can find the related trouble shooting procedure in the applicable Page Block 101.

 (1) Do the operational test of the Electronic Instrument System (Ref. AMM TASK 31-60-00-710-001).

 (a) If the test gives a different maintenance message, you can find the related trouble shooting procedure in the applicable Page Block 101.

 (2) If the fault continues:

 - do a check and repair the wiring from the DMC-1 (1WT1) or DMC-2 (1WT2) to the DMU (1TV) (Ref. ASM 31-37/01):
